7 Best Contact Lenses in Singapore

It’s hard to appreciate the beauty of the world and enjoy life if everything is blurry. Although you can use eyeglasses to see things clearly, spectacles can only give you a limited clear view as it does not cover your peripherals and blocks your vision when it fogs. While contact lenses can give you a wider clear view, it is also difficult to find one that would fit your sight needs and gives you comfort while wearing as well. With an extensive variety of contact lenses in the market, which then is the best contact lens in Singapore? In our Best of Home series, we introduce the 7 Best Contact Lens in Singapore, providing quality recommendations based on your lifestyle and budget needs.


Bausch & Lomb Soflens® 38Image Source: Bausch & Lomb SG
Ideal for beginners

Soflens® 38 is a soft contact lens. It is made from a hydrogel called Polymacon A that has 38.6% of water content on it. It keeps the lenses hydrated for comfortable daily usage. What we love about this lens is that it is not only soft but also thin and lightweight which makes it easier to insert into your eyes. Furthermore, the thinness helps the oxygen flow towards the lens to avoid dryness and discomfort on your eyes. For the first-timers, it is best to try a contact lens that is soft and comfortable to wear yet cheaper than other similar brands.

Easy insertion and removal

One thing that other contact lenses do not have is the visible tint and inversion indicator. The light blue visible tint helps you to effortlessly find the contact lens in the solution. While the inversion indicator tells you if the lens is inverted and not yet ready for insertion. Likewise, the thinness of the lens also helps in the easy insertion. On the other hand, the mid-peripheral area of the lens is a bit thicker than the central area to keep the lens from moving out of its place while applying or removing it.

Comfortable to wear

The hydrogel material on the Soflens® 38 helps repel the debris on the lens for more comfort and lesser rubbing of the eyes. It is so thin in the centre to allow more oxygen to flow to avoid dryness and redness of the eyes. You can also wear them for extended days of up to 7 days, depending on your optician’s advice.


Acuvue® Oasys for Astigmatism with HydraClear® PlusImage Source: Acuvue SG
Ideal for people with astigmatism

Most people with astigmatism wear glasses because the irregular curve of their eyes makes it difficult to find contact lenses for them. But the BLINK STABILIZED® technology on the Acuvue® Oasys for Astigmatism helps to adapt to the curvature of your eyes with every blink preventing the lens from losing its place. If astigmatism comes along with near-sightedness or far-sightedness, you can custom the lens to fit your vision needs. It can be worn for up to two weeks. But if you are planning to wear this for a day, Acuvue® 1-Day Oasys with HydraLuxe™ is an alternative.

Maximum eye protection

This contact lens blocks UV and blue rays which makes it perfect for people with astigmatism who love the outdoors or are heavy gadget-users as well. Backed up with the HYDRACLEAR® PLUS technology that has tear-like properties, your lens can retain its moisture to avoid dryness of the eye.

Money-back guarantee

Still not satisfied with your Acuvue® Oasys? They offer a 90-day money-back guarantee. This assures you that you’ll definitely not regret buying it because it meets your expectations and vision needs.


Alcon® Air Optix Night & Day® AquaImage Source: Air Optix SG
Ideal for extended wear

If you are forgetful or have a busy schedule, this contact lens is for you because you won’t need to remove it before sleeping. The material is so breathable that it allows you to wear it all day and night. And of course, we love the idea that you can sleep on it without worrying that your eyes would be damaged. We still need that clear vision whenever we wake up in the middle of the night, right? In addition, you can wear it for up to 30 days without removal. But it is still best to discuss this with your optician. Alcon® Air Optix Aqua is a cheaper option but lasts up to 6 days and nights of extended use only.

Breathable and irritation-free

Air Optix Night & Day® Aqua’s Superior Surface Technology helps to keep the irritants like debris and lipids at bay. It also allows more oxygen flow than ordinary contact lenses, so your eyes would not dry up and irritate. In fact, it is 6x more breathable than the regular soft lenses in the market.


CooperVision® Biofinity®Image Source: CooperVision SG

We absolutely love the comfort it brings to the eyes because of its Aquaform® Technology. It retains water and allows continuous oxygen flow to avoid dryness of the eyes. Even in an airconditioned room, it will not dry up your eyes, maintaining its healthy and white colour. Moreover, the lens is soft and has round edges, so you will not feel the friction once you blink or move your eyeballs. It also has an Aberration Neutralizing System™ that facilitates the improvement of vision by lessening the optical imperfection. And similar to Alcon® Air Optix Aqua, it can be worn for up to 6 days and nights in a row.


Bausch & Lomb ULTRA® with MoistureSeal® TechnologyImage Source: Bausch & Lomb SG

If your eyes are so sensitive, you will definitely love this. B & L ULTRA® has MoistureSeal® Technology that preserves up to 95% of lens moisture for up to 16 hours of wearing it. It has a water-loving molecule to keep your eyes always hydrated and avoid tiredness even after looking at electronic gadgets and screens for hours and not blinking frequently. It has an exclusive solution that is low in preservatives to still keep your eyes healthy. Another feature that we love is the visible tint that can help you find your lens when it is submerged to its very own contact lens solution.


CooperVision® Biomedics® 1 Day ExtraImage Source: CooperVision SG

If you hate having a cleaning solution with you, then Biomedics might be the answer for you! Created for daily disposal, after wearing it the whole day, you won’t need to soak it on any lens solution. You won’t be wearing it the next day, anyway. Travelling via plane? This is a convenient option for people who need to travel via aeroplane, as it is lightweight and they do not have to bring a contact lens case and solution. Moreover, its slim and lightweight design makes the wearers feel as if they are not wearing any contact lens at all. It has UV protection and can retain 55% of water content, making it ideal for outdoors too.


Acuvue® 1-Day Define®Image Source: Acuvue SG

Do you want “eye-catching” eyes while having a clear vision? This multi-purpose contact lens keeps your eyes good-looking and gives you clear eyesight. However, this is not exactly a coloured contact lens that you might be looking for. It rather accentuates or blends with your natural eye colour to highlight its beauty. Acuvue® 1-Day Define® has 7 designs to choose from to match your natural “eye-look” that you are aiming for. Visit their site so you can better see which better fits your Asian eye. And while it serves an aesthetic purpose, it still gives protection and comfort to your eyes. It has high UV protection that blocks most of the UV sun rays. And with the Lacreon® Technology, dryness and discomfort of the eyes can be avoided as it acts as a natural tear to keep the lens moist. 


We hope that our guide on the 7 Best Contact Lenses in Singapore has helped you to buy the best Contact Lens in Singapore for your clear vision and comfort in your eyes. Please share this with your family and friends if you have found it useful.


Think twice about buying contact lenses online

Contact lens manufacturers must comply with strict processes and conditions to ensure the safety and quality of their products. This is necessary as contact lenses are placed directly onto the surface of the eye, an exposed and fragile part of our bodies.

In Singapore, the Optometrists and Opticians Board (OOB) under the Ministry of Health requires all contact lenses (powered or non-powered) to be prescribed and dispensed by registered optometrists or contact lens practitioners. In addition, contact lenses with refractive power, which are classified as medical devices, must be registered with HSA.

Contact lenses bought online

While it is easy to buy attractive and cheap contact lenses online and have them delivered directly to you, non-authorised sellers cannot fully guarantee the safety and quality of their products. You may end up with way more than you bargained for.

The risks are high when buying online contact lenses from dubious or unknown sources without consulting optometrists or contact lens practitioners. Buying and using these unreliable items can lead to eye infections, corneal ulcers, or even blindness.

Any amount of money saved is not worth the irreversible harm to your vision. Avoid dubious or unknown sources and always buy your contact lenses from licensed vendors.

Consider this

Hoping to save money without considering the dangers of unreliable contact lens sources, a 17-year-old teenager bought a pair of coloured contact lenses online in 2011. The teenager soon developed an infection in one of her eyes.

The teenager experienced pain and redness that was serious enough that she needed to be admitted to hospital. She was fortunate to have recovered after treatment with antibiotics and corticosteroids, as the infection she suffered could have led to blindness if not treated in time.

Play it safe

Online sources may be cheaper or carry a wider range of contact lenses than brick-and-mortar stores, but they lack the assurance of safety and quality. In addition, eye checks are necessary for proper fitting of contact lenses. See a qualified optometrist or contact lens practice optician when you intend to use a new line of contact lenses.

Consult a healthcare professional promptly if you suffer from the following upon using contact lenses (even if you have followed good contact lens hygiene):

  • Severe eye irritation
  • Redness
  • Blurred vision
  • Pain
  • Light sensitivity
  • Unusual discomfort

Types Of Contact Lens And How They Work

Contact lens offer a good alternative to spectacles for its convenience but not many know how they work. Learn the facts from the Singapore National Eye Centre.

What are contact lenses and how do they work?

Contact lenses are thin, curved plastic discs designed to cover the cornea of the eye. They correct the way light enters the eye by improving the way it focuses on the retina. Surface tension allows contact lenses to cling onto the thin film of tears on the cornea.

Apart from vision correction, specially tinted contacts can be used to change the colour of the eyes for aesthetic purposes.

An advantage of contact lenses is that it provides for maximum peripheral vision, which is especially useful in sports and games. Contact lenses are also useful in correcting vision when the power of each eye diff ers greatly.

Most people who require vision correction can wear contact lenses. However, a small proportion with dry eyes, frequent eye infections or severe allergies may not be suitable for contact lenses.

Types of contact lenses

PMMA lenses

PMMA lenses are rigid contacts that are made of PMMA plastic. The lenses do not allow oxygen to directly reach the cornea but as the lens moves when the eye blinks, tears bring dissolved oxygen to the cornea. They are very durable and long-lasting. They are no longer sold in the market.

Rigid gas permeable lenses (semi-hard contact lenses)

Rigid gas permeable lenses are newer types of rigid plastic lenses that allow oxygen to pass directly through the lens into the eye. These lenses though less durable than PMMA lenses are more comfortable. Some gas permeable lenses can be worn for an extended period of time.

Compared with soft lenses, semi-hard contact lenses take some getting used to but are, however, less prone to deposit build-up. They offer good visual quality with lower risk of contact lens-related complications such as eye infections.

Soft contact lenses

The materials in soft contact lens incorporate water which makes them soft and flexible, and allows oxygen to reach the cornea in varying amounts.

There are currently 2 types of soft lens materials: hydrogel and silicone hydrogel. Hydrogel lenses in general have lower oxygen permeability than rigid gas permeable lenses. Silicone hydrogel lenses have higher oxygen permeability than hydrogel lenses and some are comparable to rigid gas permeable lenses in terms of oxygen permeability. In general, if you are wearing contact lenses for long hours, use silicone hydrogel lenses as these lenses are less likely to induce problems in the cornea due to hypoxia (lack of oxygen).

Soft contact lenses are among the most popular lenses in Singapore as they are very convenient, comfortable and offer a high level of convenience. Some types of soft contact lenses may be worn for longer periods of time compared to hard lenses but it is not advisable to wear these lenses overnight as the risk of developing infections of the cornea increase.

Disposable soft contact lenses

Disposable soft lenses that can be discarded and replaced daily, weekly or fortnightly are gaining in popularity because of added convenience and safety. By changing the lenses frequently, the likelihood of allergic reactions and deposit formation is reduced.

Toric contact lenses

Toric lenses correct astigmatism. They are available in both rigid and soft materials.

Blogshops in trouble after contact lenses seized, Health News

SINGAPORE – If you are thinking of buying contact lenses from blogshops or making a quick buck selling them online, think again.

You may end up losing your money, as it is illegal to import contact lenses without a license and such lenses will be confiscated by the authorities if discovered.

The Straits Times (ST) reported that at least three teenage blogshop owners have had their contact lenses seized by Custom officers and are now facing irate customers demanding their money back.

According to the ST report, at least 20 suppliers were affected after investigations were carried out by the Health Sciences Authority (HSA) and the Ministry of Health (MOH).

Since August last year, more than 1,600 pairs of contact lenses have been seized from four unlicensed importers.

One of the distributors, 17-year-old Jenny, told ST that she set up an online shop selling iris-enlarging contact lenses from South Korea and participated in a mass order with 10 other blogshops in August.

Each ordered around 50 pairs of lenses. All the lenses were confiscated by the authorities and now Jenny is unable to get back her money back to refund her customers, who paid her in advance.

They are now threatening to make a police report against her.

She admitted that she knew what she was doing was illegal, but went ahead because of the draw of making easy money.

Previously, she had placed three similar orders successfully, earning about $300 each time. She bought the lenses for $5 per pair, and sold them for $15.

Although those involved have yet to be prosecuted, blogshop owners found guilty of illegally importing contact lenses can be fined up to $50,000 and jailed for two years.

For the buyers of such lenses, Ms Irish Ng, who runs online scam alert site, told ST that as buying lenses online is illegal in the first place, it is hard for customers to get their money back if they do not get what they paid for.

In Singapore, an eye examination by a registered optometrist or optician is required before a user can be fitted with contact lenses. There have been documented cases of the usage of illegally obtained contact lenses leading to eye complications and even blindness.

HSA said that it has been stepping up its checks following a recent spate of cases involving counterfeit contact lenses.

Contact Lenses Delivered To Your Doorstep For Only S$35/Mth In Singapore

Having been an avid user of contact lenses for the past 10 years, the high costs have burnt a hole in my pocket. I grew up wearing monthly lenses but following a previous eye injury, I had to change to wearing dailies.

Averaging at S$117 for a month’s supply, news of a far cheaper alternative caught my attention. I figured I’d have to see it to believe it.

The Only Contact Lenses Subscription Service In Singapore

Located on the 3rd floor of an unassuming building along North Canal Road lies the optical studio named Two Of A Kind.

It is currently the newest (and only) subscription service on the market for contact lenses in Singapore. While different from other subscription services, it proves to be a game-changer as contact lenses have grown into a necessity for many people. 

Stepping into the studio, the minimalistic design of the interior caught my heart. The ambience exuded a certain warmness which was a stark contrast to the prim-and-proper optometric clinic I’d been expecting. 

While I loved the overall vibe of the studio, it was nothing compared to the warm welcome that founders Darryn and Javad extended to me.

From White-Collar Workers To Entrepreneurs

As the optometrist took care of the administrative proceedings that came before the mandatory eye check, they shared their journey of how they went from white-collar workers to entrepreneurs.

With their eyesight imperfections, they’ve experienced the pain of contact lens consumers first-hand. The high costs and discomfort inspired them to produce a cheaper alternative without compromising on quality.

In 2016, they ventured into research and development of possible alternatives. After two years, they successfully produced a line of contact lenses that have passed the strict scrutiny of the Health Sciences Authority (HSA) board.

Casey, the eye consultant, assisted me with the eye check. From ascertaining that their lens’ curvature would fit my eyes, to troubleshooting the problems I had with my current set of lenses, he covered them all.

He was meticulous throughout the process, even pointing out problems like the residual effect of my previous eye injury. 

It took a longer period of time to test for my degree than usual, but he explained that it was due to my astigmatism and he was trying to mimic my degree as best as he could. 

I was given a pair to try on the spot, to ensure the fit and degree was to my comfort; they felt more comfortable than the lenses I had on before.

Following which, he continued to run a few more tests to confirm the compatibility of my eyes with these lenses. Their insistence on ensuring that the lenses I went home with was as close to perfection astounded me. 

I Wore These Lenses For The Next Five Days

Despite not making a commitment to make a subsequent purchase, I left the studio that day with five pairs of trial lenses completely free-of-charge. With year-long subscriptions starting at a mere S$35/month, it was hard to stop myself from immediately signing up, but I needed to see if they would work for me first.

I wore these lenses for the next five days to judge how they would fair, given my extended usage of nearly 14 hours every day. To my surprise, they stood up to the test.

My eyes usually tear up at the eighth or ninth hour of wear, as an instinctive reaction to curb the dryness but these lenses stayed comfortable and moist, and gave me clear vision throughout the day.

At the moment, they only offer clear, daily contact lenses that do not cater to those with astigmatism like myself. Instead, they’ll help you bump up the degree to get as close to clear vision as you can.

However, do note that these do not measure up to the lenses that are made-to-order for those with astigmatism. But fret not– Two Of A Kind is looking into producing lens suited for astigmatism in 2019. Hurrah! 

Oh, and be sure to make a prior appointment to reduce your waiting time. So long, overpriced contacts!

The main differences between daily, biweekly and monthly lenses are the amount of care you need to give the lenses and their prices. Daily ones don’t need cleaning as you throw them away at the end of the day. Do you prefer a pair for occasional wear? Or do you suffer from any allergies? If so, a pair of daily lenses would be most suitable for you. Biweekly and monthly ones are more suited for those who prefer to wear contact lenses frequently and who may be more price sensitive.

Toric lenses are suited for those with astigmatism. People with astigmatism require a special design to correct refractive errors due to their irregularly shaped corneas. Toric lenses are available with most leading brands such as Acuvue, with the options of daily, biweekly and monthly. Those unsure of whether they have astigmatism can take our contact lens exam in Singapore.

Coloured contact lenses help to enhance your look. They can complement the natural colour of your eyes or add a bold touch to your outfit with a totally different hue.

90,000 Success of CooperVision® MiSight® Daily Contact Lenses for Controlling Childhood Myopia Coming in 2020 in the United States.

FDA approval opens up new perspectives for parents, children and healthcare professionals.
This contact lens will be the first and only product of its kind available in the United States.

SAN-RAMON, California. November 18, 2019 CooperVision ® announced that it has received FDA approval for its innovative MiSight ® 1 day 1 contact lens.MiSight ® 1 day is a daily contact lens that is the first and only FDA approved product 1 to slow the progression of myopia (nearsightedness) for primary use in children ages 8 to 12 * .

“We cannot overemphasize the importance and future impact of this landmark decision on children’s vision, especially given the rise in myopia in the United States and around the world. Ophthalmologists who use this successful method will improve the quality of life and eye health for many children, ”says Daniel J. Daniel G. McBride, President, CooperVision ® .

In myopia, light rays are focused at a point in front of the retina, and not on its surface due to the increased length of the eye. The progression of myopia is associated with future vision-threatening conditions such as cataracts, retinal detachment, glaucoma 2 and myopic maculopathy 3 . Even children with mild myopia have a higher risk of developing glaucoma and retinal detachment in the future 4 compared to their nonmyopic peers, and the risk increases as myopia progresses 5 .This is confirmed in a 2015 report by the World Health Organization (WHO), which stated that “myopia and high myopia are on the rise worldwide at alarming proportions, with a significant increase in the risk of visual impairment due to pathological conditions associated with high myopia “ 6 .

Until now, traditional glasses and contact lenses available in the United States have only been developed to correct blurry vision, which is a symptom of myopia, but have not been approved to slow its progression.

CooperVision ® conducted an in-depth, comprehensive study on the effectiveness of MiSight ® 1 day. It includes a prospective, multicenter, double-blind, randomized, multi-year study of 144 myopic children aged 8–12 years from Singapore, Canada, the United Kingdom and Portugal who were in the FDA approved age range for initial contact lens fitting 1 . Three-year research results published in Optometry and Vision Science in August 2019.showed that the use of MiSight ® 1 day slows down the progression of myopia: by 59% when measured by the mean spherical equivalent (SE) with cycloplegia and by 52% when measured by the mean increase in the axial length of the eye * .

The study showed encouraging results over four and five years when MiSight ® 1 day 7 lenses were fitted to the original control group. Some of the children continue to wear these contact lenses into their older teens.

“CooperVision ® is more committed to innovation in ophthalmology than ever before. The time and effort we put into getting FDA approval was well spent. We are innovating the treatment of myopia for ophthalmologists in the US that will benefit countless children across the country, ”said Jerry Warner, Executive Vice President, Americas and Global Commercial Operations, CooperVision ® .

MiSight ® 1 day lenses will be launched in the United States as part of the CooperVision ® Myopia Control Initiative starting in March 2020.The lenses are already successfully worn by thousands of children with myopia worldwide, including Canada, the United Kingdom, Spain and Australia. where age ranges for starting lens use may differ 7 . They have been recognized as one of the most innovative developments in ophthalmology by the British Contact Lens Association and the international media industry.

“Over the past few years, childhood myopia has increased in prevalence and severity 8 , and in my practice I am always looking for new solutions, tools and ways to educate my patients and their parents on how to best deal with myopia,” says Katherine Schütz (Katherine Schuetz), Doctor of Optometry [OD] at Little Eyes Pediatric Hospital and Revolution EYES. “With the FDA approval for MiSight ® 1 day contact lenses, originally intended for children 8–12 years old 1 , ophthalmologists have finally developed a way to show that myopia is slowing down in these children.I am even more confident in this, as the effectiveness of these lenses has been proven by many years of clinical data and international experience in the market. ”

Usually myopia occurs in school-aged children and progresses to 20 years old 2 . According to a study published in the journal Clinical Ophthalmology in August 2018, 41.9% of children in the United States develop myopia between the ages of 5 and 19 9 . This is partly due to a lifestyle change for children, in which they rest less time and spend more time looking at nearby objects, such as digital screens.

“While there is a growing awareness and interest in stopping the progression of myopia, it is imperative to act urgently and as early as possible. We believe the MiSight ® 1 day lenses will help ophthalmologists move forward faster and will also contribute to a deeper parental awareness of the issue of childhood myopia. It is a privilege to be at the forefront of myopia control. By working with many ophthalmologists and passionate parents, we have already made a significant contribution to the fight against myopia and can now expand our efforts in the United States, ”says Michele Andrews, MD, Optometry Senior Director, Professional and Academic CooperVision ® North American inquiries.

90,000 Contact Lenses and Year 2006

Based on the data of the research agency Eurolens Research for 2005, it can be assumed that the structure of the contact lens market at the beginning of 2006 did not have time to undergo any significant changes.

World trends

Based on the data of the Eurolens Research agency research for 2005, it can be assumed that the structure of the contact lens market at the beginning of 2006 did not have time to undergo any special changes, since this market is rather inert. It should also be noted here that any averaging is, of course, approximate, since the indicators between different countries sometimes differ by an order of magnitude, depending on the state of their economy, national characteristics, traditions existing among contactologists.

By the beginning of 2006, a gradual decline in fittings of rigid lenses continued for both primary patients and returnees. If at the beginning of 2005 the proportion of fittings of such lenses to primary patients was 11% of all fittings for “beginners” and 15% of the number of repeated fittings, then at the beginning of 2006 these indicators decreased to 10 and 11%, respectively. At the same time, naturally, in a number of countries, in particular in Russia, Sweden, Norway, this indicator is significantly lower than the average, while, for example, in Germany and Japan it is much higher. Thus, at the beginning of 2006, the tendency towards a decrease in the proportion of rigid contact lenses in the total sales volume continued. Here, however, it should be noted that it was the share, and not the absolute indicators of sales that decreased, since the market itself in terms of sales increases from year to year, and an interview with representatives of leading manufacturers of rigid lenses, conducted by us at the end of 2006, shows that these companies are quite optimistic.

One-month scheduled replacement lenses continue to dominate sales volumes, with the exception of the US, Japan and Singapore markets, where soft lenses are more popular with one- and two-week wear periods.The share of traditional lenses continues to decline. In ten countries surveyed by Eurolens Research, the share of lenses sold less than once a month averaged 2% of total sales. One-day soft contact lenses are in good demand – on average, they are selected by doctors in 15% of patients. There is also a significant difference between countries: if in the UK, Singapore and Norway more than 30% of all patients are prescribed daily lenses, then in the USA this figure is only 4%, and in the Netherlands – even 3%.

With the advent of the daytime ideology of silicone hydrogel contact lenses, which were originally positioned as lenses for extended 30-day wear, the structure of their sales has also changed. In the USA and Canada, for example, such lenses are prescribed to primary patients in 30% and 25% of cases, respectively. There is a growing trend in the selection of silicone hydrogel soft contact lenses specifically for daytime wear. As for the prolonged mode of wearing lenses made of silicone hydrogels, on average, contactologists prescribe this mode to 10% of their patients.

New on the contact lens market

In terms of new products, the past year was somewhat poorer than in 2005. Companies either changed the names of existing lenses, or expanded the range of their parameters, but they were in no hurry to present new items to the public. Rather, they only voiced their intention to start selling such lenses.

Among the new products are Biofinity silicone hydrogel contact lenses, presented by Cooper Vision, in particular, during the 30th Clinical Conference of the British Contact Lens Association (BCLA). According to the company itself, the creation of this lens is a breakthrough in the silicone hydrogel contact lens sector. What does it consist in? It has been found that in silicone hydrogel soft contact lenses, the oxygen transmittance (Dk / t) decreases with increasing moisture content. Cooper Vision has succeeded in developing a technology called Aquaform, which allows the manufacture of silicone hydrogel lenses with a high moisture content and high oxygen transmission at the same time.It has also been shown that in traditional lenses made of silicone hydrogels, with an increase in oxygen transmission, the elastic modulus also increases. That is, lenses with a high Dk / t are quite elastic, which negatively affects the wearing comfort. Aquaform technology achieves higher oxygen permeability at the same modulus of elasticity as commercially available silicone hydrogel lenses. In other words, it became possible to produce softer and more comfortable lenses with a Dk / t value> 87 • 10–9 units. Fatt, which meets the criteria for safe continuous wear (according to Holden and Mertz).

Cooper Vision has conducted a study of 2,100 patients living in Europe and wearing soft contact lenses. As shown by its results, 38% of patients do not wear lenses all the time, day in and day out, and 48% do not do it because of the discomfort experienced. At the same time, those who wore silicone hydrogel soft contact lenses more often complained of discomfort. But even those who have switched to the new 2-week silicone hydrogel lenses of the second generation face the problem of discomfort (albeit to a lesser extent).Accordingly, the industry of contact vision correction is facing the challenge of developing a comfortable silicone hydrogel contact lens. Cooper Vision has been dealing with this issue for a long time, and today its specialists believe that their new product Biofinity is precisely this long-awaited lens.

Biofinity soft contact lenses have the following characteristics: lenses are made of Comfilcon A material, oxygen transmission index Dk / t = 160 (for a refractive lens –3. 00 diopters with a center thickness of 0.08 mm), moisture content – 48%, modulus of elasticity – 0.75 MPa.The surface of the lens is not subjected to special treatment (but at the same time it is perfectly moisturized, non-hydrophobic), and its design is designed to correct optical aberrations.

As for wearing the new Biofinity lenses in continuous (up to 30 days) and prolonged (up to 7 days) modes, we have all the data for this. According to the results of a study by Fonn and other specialists (Fonn et al., 2005), nocturnal corneal edema during sleep in Biofinity lenses was 4.1% (for comparison: when sleeping in Night & Day lenses, this figure is 4.0%).Thus, Biofinity soft contact lenses can be worn in any mode: daytime, flexible, prolonged and continuous.

Note that, despite the presentation made back in May 2006 during the BCLA conference, sales of new Biofinity soft contact lenses have not yet begun even on the US market, although in December 2005 the FDA (US Food and Drug Administration) cosmetic products) has issued a permit for their positioning on the market as lenses for daytime wear. According to advertisements on the websites of Internet suppliers of soft contact lenses, sales were delayed until January-February 2007 (it is possible that by the time you read this material, they will have already begun).

In 2006, CIBA Vision re-branded its trademarks – soft contact lenses O2Optix, which received the name Air Optix, and Focus Night & Day, which at first “lost” the word Focus, and are now called Air Optix Night & Day. Air Optix silicone hydrogel soft contact lenses are planned to be produced in toric version, at least they have been talking about it for a long time.As part of the last BCLA conference, the company presented new toric lenses. According to press releases circulated by her, the new Air Optix Toric lenses, despite their toric design (which implies an increase in thickness in some areas of the lens – for stabilization), like their spherical counterpart Air Optix, have an excellent oxygen transmission rate, which is 5 times higher than planned replacement hydrogel lenses. The lens surface undergoes a special plasma treatment during production, which creates a biocompatible, wettable, deposit-resistant structure.The toric lens edge design is the same as the Air Optix, all the way around. Prismatic ballast was used as a stabilization method. The stabilization zone of the lens is designed to minimize interaction with the lower eyelid and thus contribute to a comfortable wearing experience.

A clinical trial of the new toric lens was carried out in France. It was attended by 79 ophthalmologists who selected Air Optix Toric for their patients.According to the results obtained, in 99% of cases the fitted lenses demonstrated an acceptable level of stabilization, in 87% of cases the lenses were fitted on the first try, 92% of doctors expressed satisfaction with the new lens. The test subjects themselves reported improved comfort, vision quality and ease of handling compared to the toric lenses they had previously worn.

The company’s assortment this year also includes colored daily lenses under the FreshLook One Day brand. These lenses combine two technologies: the creation of the ColourBlends three-in-one color pattern and the production of daily lenses using Lightstream technology. Since no maintenance is required for these soft contact lenses, the company expects more people to take the opportunity to temporarily change their eye color. The lenses are available in four colors: Pure Hazel, Blue, Green, Gray. One pack of lenses consists of 10 blisters.The refractive range is from 0.00 to –6.00 diopters in 0.25 diopters increments.

In early 2006, Johnson & Johnson Vision Care’s Acuvue Oasys silicone hydrogel contact lenses (which officially reached Russia in October this year) were approved by the FDA for extended wear. Acuvue Oasys has been approved for wearing for 6 consecutive nights (7 days) following tests that have confirmed that the lenses are safe for the health of users. According to the company’s specialists, short-term prolonged wearing is safer for patients than longer periods of wear. In the fall, during the competition for the Grand Prix of the International Optical Salon SILMO-2006, Acuvue Oasys lenses were recognized as worthy of this high award.

Also in 2006, Johnson & Johnson Vision Care began to gradually introduce new toric one-day lenses to individual markets, dubbed 1-Day Acuvue for Astigmatism. At the BCLA conference in May 2006, we received information that so far such lenses are available to patients and doctors only in Japan.In the fall, it became clear that the new “fly-by-night” went on sale in the United Kingdom.

In addition, the official Singapore website for the Acuvue family has announced two new lens names: Acuvue Clear and 1-Day Acuvue Define. The former are marketed as planned replacement lenses, ideal for both primary and experienced contact lens wearers. In turn, 1-Day Acuvue Define are daily soft contact lenses with a colored ring pattern to enhance the expression of the patient’s eyes.The illusion of an increase in the size of the iris is created, the eyes acquire shine. As with Acuvue 2 Colors and 1-Day Acuvue Colors, the color layer in 1-Day Acuvue Define is enclosed within the contact lens and is surrounded on the outside and inside by Etafilcon A. The company produces these lenses in two varieties: Accent Style and Vivid Style … The first allows you to emphasize the elegance, the look in such lenses looks more “classic”, the second – to show cheerfulness, in such lenses there is more expression and activity.It should be noted that 1-Day Acuvue Define lenses were developed specifically for the Asian market, when calculating the diameter of the pattern ring, the dimensions of the diameter of the iris in Asians were taken into account.

At the end of 2006, hints appeared in the professional press that Johnson & Johnson Vision Care, through its Vistakon division, had an eye on a market it had not yet mastered – the market for solutions for the care of contact lenses. In this respect, the company stood apart from other market giants such as CIBA Vision and Bausch & Lomb, which produced a wide range of care products. According to a comment by Don Casey, head of product division at Vistakon, the company sees significant potential in this market. Recent events leading to the withdrawal of ReNu with MoistureLoc from the market have freed up a lot of space on it for innovative products from Johnson & Johnson Vision Care. Given the immense visibility and popularity of the Acuvue brand, as well as the company’s vast experience in the development of contact lenses, it is likely that it has all the prerequisites for starting a good business in the field of lens care products.Perhaps it will be a licensed solution, or maybe developed in the bowels of Johnson & Johnson Vision Care itself. In any case, these are just the only bits of information available to us. But, as you know, there is no smoke without fire.

Bausch & Lomb has rebranded the popular Soflens Comfort monthly soft lenses, which have undergone some enhancements and are now referred to as Soflens 59 (59 stands for moisture percentage). The changes affected both the blisters and the cardboard packaging in which they are located. The new blister has a smooth, removable label and is easy to open, which is especially important for those patients who do it for the first time in their life. The blister has received an ergonomic design, it is comfortable to hold it in your hands while manipulating with your fingers. The packaging is now decorated in the new corporate style of Bausch & Lomb, the company logo is clearly visible on it, the SofLens trademark is highlighted in a bright font.

In 2006, the company also actively promoted SofLens Multifocal presbyop lenses on the markets of various countries, expanding the range of available parameters.

In 2006, ClearLab offered an original solution in the packaging of soft contact lenses. In the fall, it was reported that the company was developing and preparing to market a package with a thickness of only 1 mm for one-day soft contact lenses, called AquaSoft Singles, a patent for them registered in the United States and Japan. Within the next two years, such lenses are planned to be presented in the markets of different countries of the world. According to available information, a pack containing 30 one-day AquaSoft Singles soft contact lenses will take up the same space as a pack of two blisters (one lens each) of conventional hydrogel lenses currently takes.This will undoubtedly be very convenient for the patients.

Sauflon has launched Synergi, a new multifunctional solution (MFR). According to the information provided by the manufacturer, MFR is based on a combination of cleaning, disinfecting and lubricating agents under the general name Oxipol. A distinctive feature of Synergi is that it does not contain any preservatives at all. As is known, peroxide systems have so far possessed such properties. But just Synergi is not a peroxide system, which means that when using this MPF, there is no need to neutralize hydrogen peroxide.In addition, as follows again from the company’s press release, the disinfectants included in Oxipol decompose into oxygen, salts and water, and the released oxygen has a beneficial effect on the state of the cells of the cornea.

Sauflon has developed an antimicrobial container for contact lenses especially for Synergi. Silver ions are somehow integrated into the container, which are designed to destroy pathogenic microorganisms.

Solution market fever

Remembering the past year, one will involuntarily have to dwell on the event that literally shook the trading world: the recall by Bausch & Lomb of its new ReNu with MoistureLoc solution from the markets of all countries in connection with suspicions of contributing to this outbreak of the fungal infection Fusarium keratitits (fusarium keratitis).The story goes back to November 2005, when the Hong Kong Ministry of Health notified Bausch & Lomb that there was an outbreak of this eye infection among soft contact lens wearers who, among other things, used a product made by this eye to care for their lenses. company. Bausch & Lomb conducted a corresponding study, but found no confirmation that the solution was to blame, and in early 2006 the case was closed.But in mid-February, the company received a report from the Ministry of Health of Singapore, which said that there was an outbreak of fungal infection Fusarium keratitits among users of soft contact lenses, and most of the patients used ReNu with MoistureLoc solution for care. Based on a report from Singapore, the Hong Kong Ministry of Health also reported that in February 2006 it was seeing an abnormally high rate of Fusarium keratitits infections among soft contact lens wearers, most of whom also use ReNu with MoistureLoc.Upon receiving this information, the company immediately suspended sales of the solution in these two countries. Thousands of expensive tests were carried out in a short time, but none of them showed that the solution could have been contaminated during production or was ineffective against this type of fungus.

In parallel, according to routine, Bausch & Lomb continued to collaborate with various government agencies that regulate health issues, in particular with the North American FDA and the Centers for Disease Control (CDC).The company set out to find out if there is a similar correlation between solution and infection in other countries. As a result, on April 10, 2006, a report was received from the CDC, which stated that there were about 100 suspicions of Fusarium keratitits infection and that the majority of patients used ReNu with MoistureLoc solution. If initially the company made the assumption that the outbreak of fusarium keratitis was most likely associated with the peculiarities of the tropical climate in Hong Kong and Singapore, now suspicion has fallen on a plant in the American city of Greenville, which supplied the solution to these countries and the United States.The company immediately stopped worldwide sales of the solution produced at the plant, and a few days later urged retailers to remove the solution from store shelves and notified patients to stop using the solution.

The Bausch & Lomb specialists were at a loss: after all, during the tests during the implementation of the procedures for admitting the solution to the market, it was shown that ReNu with MoistureLoc reduces the number of Fusarium solani fungi colonies by 4 logs.units, which significantly exceeds the requirements of ISO – a reduction of 1 log. unit! An FDA / CDC inspection at the Greenville plant found no sources of Fusarium solani infection in sterile or non-sterile production areas, nor were there any differences from the production process at the Milan plant, which also produces the solution. Investigation of the samples of Fusarium solani that caused the infection showed that they were different from each other, thereby excluding their origin from one common source, which could be a plant.Moreover, ReNu with MoistureLoc has been shown to effectively kill the Fusarium solani fungi that directly cause the infection.

Further, the question was studied whether the patient’s non-compliance with the rules for using the solution contributed to the development of infection. The lens containers used by the infected patients were found to be dirty, contaminated with microorganisms, some of them with microcracks. Dirt was also found on the containers with the solution, especially on the neck.It was also found that many patients, after storing the lens at night, did not pour out the used solution, but refilled it with fresh one from the package. The solutions were kept uncovered. The company tried to find out the influence of such factors of egregious non-compliance with the manufacturer’s recommendations on the antifungal efficacy of the solution. As it turned out, during evaporation (when the container with the solution is open), the effectiveness of ReNu with MoistureLoc against fungi decreases – in contrast to the ReNu MultiPlus solution.

As a result of numerous tests and studies, the following conclusions have been drawn.According to the company’s specialists, non-compliance with the recommendations for the care of contact lenses, as well as adding a fresh solution to an already used one, can lead to a decrease in the disinfecting properties of the solution. Evaporation of moisture from a solution with an open container increases the concentration of polymers in it, which can lead to a decrease in antimicrobial effectiveness – in particular, when storing the lens in an open container. Other violations of instructions for the care of contact lenses by affected patients also contributed to the development of infection.Further, Fusarium solani fungi can become trapped in a plastic film that forms on the surfaces of the lens storage container, which then acts as a protective shield for them. The combination of a number of unfavorable factors, which, contrary to the laws of probability, still took place, led to an outbreak of a fungal eye infection.

An important fact from Bausch & Lomb’s point of view was that the company’s other solutions – ReNu MultiPlus and ReNu – did not appear in the CDC report as having a correlation with the outbreak.Their chemical composition is fundamentally different from the composition of ReNu with MoistureLoc. In the most extreme tests, they have shown high efficacy against fungi. It is ReNu MultiPlus that is designed to fill the niche in the market of solutions, formed after the withdrawal from sales of ReNu with MoistureLoc.

Thus, May 15, 2006 – the day of the official announcement of the company to withdraw the solution from the market – became a black date in the history of contact vision correction, and in particular of Bausch & Lomb, on whose financial shoulders the burden of losing $ 100 million fell.lost profits from the sale of a new solution, as well as multi-million dollar testing and research costs. Nevertheless, in the general balance sheet of the company, the losses were not so great as to shake it. Moreover, in the next 18-24 months, Bausch & Lomb plans to launch a new multifunctional solution on the market.

The year was drawing to a close when it became clear that not only Bausch & Lomb was unlucky in it. It seems that the solution sector has started to seriously fever – in November 2006, Advanced Medical Optics (AMO), a well-known manufacturer of MCL care products, issued a press release informing that it was forced to initiate a recall process for products already released to distributors.

According to an AMO official report, the problem originated in the company’s factory located in China. The nature of this problem is such that it can affect the sterility of the solutions discharged on the conveyor. 2.9 million units of products are subject to recall, of which 183 thousand were sent to suppliers in the United States, and the rest went to the markets of Asian countries and Japan. Fearing conjectures that could easily be born in the creative minds of journalists, still under the impression after Bausch & Lomb’s withdrawal of the ReNu with MoistureLoc solution, AMO stated that the problem is related precisely to the state of production, and not to the peculiarities of the chemical composition of the solutions, each of which is already for several years it has been successfully used for the care of contact lenses.It is extremely unlikely that patients will run into problems when using solutions from a Chinese factory, but the AMO has decided to withdraw all shipments from the factory.

A breach of sterility was found on several production lines, so the decision was made to completely close the factory to sterilize and fix the problems. The enterprise is shut down for an estimated 10–12 weeks. At the same time, the problem does not in any way affect the AMO factory in Spain, which is the main source of supplies for its products in the USA and European countries.The products manufactured at this factory will be delivered to these countries without changes in volumes according to the plan. The company estimates that the costs of resolving the problem will be between $ 35 million and $ 40 million, which will undoubtedly affect the financial results of the fourth quarter.

The problem, as we can see, is of a slightly different nature than it was in the case of ReNu with MoistureLoc, where the peculiarities of the chemical composition in combination with a poor culture of handling soft contact lenses led to an outbreak of an eye infection with Fusarium keratitits.

This was approximately the year two thousand and six for contact correction. Of course, you cannot cover everything in a brief review, beyond its borders are still the next litigation that began between large manufacturing companies over patent rights for a particular product and takes away a lot of their time and millions of dollars, government intervention in the regulation of the contact correction market vision, which does not always have a beneficial effect on the work of contactologists, and other aspects.In general, the market continued to move in the direction set in previous years. This is the development of the segment of silicone hydrogel lenses, the popularization of daily lenses, the promotion of toric and multifocal soft contact lenses, the growth of recognition of orthokeratology. All this will migrate in the year two thousand and seven – which, hopefully, will delight us with new products, and that, in turn, will come even closer to the so far unattainable “ideal contact lens”.

Internet glasses and contact lenses.Physics of the Future

Today, we keep in touch with the Internet using computers and cell phones. But in the future, the Internet will be everywhere.

There are several ways to bring the Internet connection to the lens. The image can be transmitted from glasses through the lens of the eye directly to the retina. You can also project an image onto a lens, which in this case will act as a screen. Or you can attach the screen to the frame of your glasses, like a tiny lens that jewelers use.Looking through the glasses, we will, as if on a movie screen, see the Internet screen in front of us. At the same time, a remote control device in our hands will allow us to control the actions of the computer wirelessly. Or you can just wiggle your fingers in the air and thus control the image – after all, the computer constantly registers the position of our fingers.

For example, scientists at the University of Washington have been developing a virtual retinal display (VRD) since 1991, a device in which red, green and blue laser beams are projected directly onto the retina of the eye.With a resolution of 1600 x 1200 dpi at a 120 ° angle of view, a VRD monitor can produce a vivid, life-like image comparable to a movie screen. The device for generating an image can be built into a helmet, into special or ordinary glasses.

I back in the 1990s. I had the opportunity to test such Internet glasses, one of the first of their samples, developed by scientists at the Massachusetts Institute of Technology (MIT) media laboratory. Outwardly, this device looked like ordinary glasses, only on the right and slightly from the side an additional cylindrical lens about half an inch long was attached to them.In the usual position of this additional lens, I could see perfectly through glasses, but it was enough to press lightly with my finger – and a tiny lens took up space in front of the eye. At the same time, an easily distinguishable image of a computer screen appeared in front of me, at a glance slightly less than a standard one. It was surprisingly clear; it seemed that you were looking directly at the screen. Moreover, picking up a small – the size of a cell phone – device with buttons, I was able to control the cursor on the screen and even type commands.

In 2010, when I hosted a Science Channel program, I visited Fort Bennings, Georgia, and saw the latest model of the US Army’s Internet for the Battlefield, called the Infantryman. I put on a special helmet with a miniature screen attached to the side. Moving the screen so that it was in front of my eyes, I suddenly saw a striking sight: a panorama of the battlefield, on which crosses indicated the location of friendly and enemy troops.The “fog of war” suddenly dissipated, PS-sensors accurately determined the position of military units, tanks and buildings and marked the terrain on the map. As soon as a button was pressed, the image instantly changed, opening the Internet to me right on the battlefield and providing me with information about the weather, troop dispositions, strategy and tactics.

In a more advanced version of the device, the Internet screen could be projected directly into the eye through contact lenses with a chip embedded in the plastic and an LCD screen.Babak A. Parviz and his team at the University of Washington in Seattle are developing a base for Internet-enabled contact lenses; so far, this is only a prototype, but later such technology may change the usual technique of Internet access.

Parviz believes that one of the closest applications of this technology could be a device for continuous monitoring of blood glucose levels in diabetics. The lens will show you the current values ​​of the parameters that characterize the state of your body.But this is just the beginning. Parviz is confident that the day will come when we will be able to download any films, songs, websites or newsletters from the Internet and see them on a contact lens screen. In essence, the lens will become the screen of a fully functional entertainment center, and you can enjoy feature films lying on the couch. Through the same center, it will be possible to connect to an office computer and gain access to files and programs stored there. It will be enough to blink an eye to contact the office right from the beach and organize a video conference.

By adding image recognition software to your Internet glasses, you will be able to see objects and even people’s faces in front of you. Already today, some recognition programs can recognize previously entered faces with more than 90% accuracy. And then, at the beginning of the conversation, you will see in front of you not only the name of the person, but also his biography and characteristics. In society, this will help avoid the awkwardness of meeting a familiar person whose name you cannot remember.At a crowded party where unfamiliar or completely unfamiliar people gather, this function will become even more useful, because among the guests there may be very important persons with whom you are not yet familiar. The described system will help you recognize them by sight and get some information about them without resorting to outside help, practically during a conversation. (Remember how the robot saw the world in the movie “The Terminator”; approximately the same way a person will see the environment in the Internet glasses of the future.)

As a result, the education system can change dramatically. In the future, students on the exam will be able to discreetly scan the Internet using contact lenses and find answers to any questions there; it will be difficult for teachers with a focus on rote learning to catch such a student. This means that teachers will have to pay special attention to testing the ability to reason and think logically.

You can also integrate into the frame of your Internet glasses, for example, a tiny video camera that will capture the environment and transmit the picture directly to the Internet.People around the world will be able to experience with you what is happening in your life. Whatever you look at, thousands of people will be able to see it with you. Parents will know what their children are up to. Lovers will be able, being apart, to share their impressions. Spectators at concerts – to convey their delight to other fans of their favorite artists. Inspectors visiting remote company locations will be able to keep the boss informed of what is happening. (Or an everyday example: one of the spouses walks around the store, and the other comments on products and gives out valuable shopping instructions.)

Parviz has already managed to make a flat computer chip that can be placed inside a polymer film – a contact lens. He also managed to fit an LED into a contact lens and is now working on a lens with an 8×8 matrix of LEDs. Its lens can be controlled wirelessly. Parviz states: “Over time, these components will contain hundreds of LEDs that will form all kinds of images in front of the eye – texts, diagrams and photographs. Much of the detail is translucent, so users can navigate the real world without bumping into objects or losing their sense of orientation. “The ultimate goal of the researcher – and it is still far away – is to create a contact lens from 3,600 points no more than 10 microns thick.

One of the great advantages of internet contact lenses is their low power consumption, only a few millionths of a watt, so they are very economical and will not drain your battery. Another advantage is direct access to the human brain without the need to implant electrodes (since the optic nerve in a certain sense can be considered an extension of the brain).It should be noted, however, that the eye and optic nerve transmit information at a speed that surpasses the speed of a high-speed cable Internet connection. Thus, the Internet contact lens represents perhaps the most efficient and high-speed access to the brain.

Transmitting an image to the eye through a contact lens is somewhat more difficult than through Internet glasses. An LED can generate a point of light, or a pixel, but a microlens must be added to focus this point directly on the retina.The resulting image will seem to hang in the air in front of your eyes at a distance of a little over half a meter. In a more advanced scheme, which Parviz is currently working on, it is supposed to use microlasers to deliver a sharp image to the retina at once. Using the same etching technology used in the manufacture of microprocessors to etch tiny transistors, it is possible to etch tiny lasers of about the same size – the world’s smallest lasers – onto silicon wafers.The technology, in principle, makes it possible to manufacture lasers with a transverse size of about 100 atoms. As with transistors, it is technically possible to fit millions of lasers onto a fingernail-sized substrate.

How lenses with needles treat eye diseases

Sometimes the information about the treatment process sounds worse than the disease itself. Scientists recently invented a dissolving lens device to better combat eye diseases.

A research team in Singapore has developed a new treatment for glaucoma and macular degeneration. This new method turned out to be a tiny lens covered with barely visible needles that deliver drugs directly to the eyeball.

It looks not very pleasant, but it is not as painful as it seems at first glance. According to a study by the Singaporean team, which was recently published in the journal Nature Communications, the needles are so small that they do not cause any pain, at least in laboratory mice.

How do these lenses work? First, the patient places them on the eyes, like contact lenses, after some time, carefully removes them, so that the needles remain in the cornea. The outer layer of each needle dissolves quickly, thus delivering the required dose of medication, but the needle only dissolves completely over time, while delivering more of the desired drug directly to the eye.

This is undoubtedly a new and innovative way of administering medication to the eye compared to eye drops, which require frequent use and may be less reliable.

Researchers in Singapore claim that their lenses are 90% effective in treating laboratory mice with a disorder in which blood vessels grow into the cornea. Scientists plan to conduct additional tests to see if this method causes any unwanted side effects in mice, and if they don’t, the researchers hope that one day they will move on to testing these lenses in humans.

This project of lenses with needles can serve as a home treatment for any eye disease, but only as long as people are brave enough to put such lenses on their eyes.

90,000 CONTACT LENSES: Risks and consequences of wearing

From an aesthetic point of view, contact lenses are a godsend for people with vision problems. The only question is: “Do lenses harm human health, especially the eyes?”

You are not just a human being … You are a microbial creature that is home to nearly 100 trillion bacteria, fungi, viruses and other microorganisms that make up the microflora of your body.With the advancement of science, it has become clear that these organisms play a fundamental role in health, both mental and physical. Most of the research done to date has focused on the role of microbes in gut and skin health, but this is just the beginning.

Contact lenses: benefit or harm

The eyes also have a microbiome, but this is so neglected by researchers that its function is still unknown. A new study, presented at the annual meeting of the American Society for Microbiology, has finally begun to piece the puzzle together by studying the bacteria colonies living in front of people who wear contact lenses and those who do not.

Their findings support the growing knowledge that modern lifestyles affect our microbiome … with potentially dangerous consequences.

Wearing contact lenses alters the microbiome of the eyes

Comparison of the number and types of bacteria on the surface of the eyes showed a greater diversity of microorganisms in wearers of contact lenses than in those who do not.

The eye microbiome of people who wear contact lenses is more like the skin microbiome because it contains three times as much:

  • Methylobacteria, living in soil, wastewater and plant foliage
  • Lactobacillus, living in the digestive tract and urinary tract
  • Akinetobacteria, in soil and water (believed to be responsible for most infections)
  • Pseudomonas, which are widespread in the environment and can lead to ear infections and other serious problems, including corneal infection

This is big news for the 71 million people who use contact lenses worldwide, as some of these microbes are associated with inflammatory eye conditions such as conjunctivitis, keratitis (corneal infection) and endophthalmitis.

This may be one of the mechanisms by which contact lenses increase the risk of eye diseases and infections.

It is believed that the constant touching of fingers leads to a disruption of the microbiome – microbes enter the eyes from them, the number of which is not so great under normal conditions.

In addition, it can be caused by a change in the eye’s immune system due to the direct pressure of the lens on the eye.

In addition, skin bacteria can enter the eyes through contact lenses.

Senior Researcher Maria Gloria Dominguez-Bello, microbiologist at New York Langon Medical Center, notes:

“Our research clearly shows that placing a foreign body, such as a contact lens, into the eye is not neutral.”

Is there a link between the microbiome and dry eye syndrome?

While we are only getting closer to understanding the eye microbiome, there is evidence that it may play an important role in eye health.

Based on a proposed study sponsored by the Singapore National Eye Center:

“In the course of evolution, various microbes, especially bacteria, colonized the surface of the eyeball as opportunistic microorganisms. Their role is to maintain homeostasis of the ocular surface.

The innate immunity of the surface tissues of the eye is very active and consists of active mechanisms of suppressing inflammation. So, it contains macrophages, dendrocytes, TS-lymphocytes, regulatory T-lymphocytes, B-cells, immunoglobulin-A, lysozyme, antimicrobial peptides and barriers from external agents.

Common opportunistic microorganisms on the surface of ocular tissues maintain the basal level of innate defense activation by stimulating pattern recognition receptors in the epithelial cells of the ocular surface.

This normal microbial composition is important because inflammation and infection occurs when a pathogenic strain is introduced that is stronger than the flora, or if the dominant strain produces overly immunogenic products.

The proposed study wants to determine if dry eye syndrome is microbial in origin.

“Since dry eye syndrome is a known inflammatory disease of the surface of the eye, this is one of the ways in which microbes can contribute to the development of pathology,” the researchers note.

Eye Microbiome Project

The Human Microbiome Project, launched in 2008 with funding from the US National Institutes of Health, is “to describe the microbial communities found in many locations in the human body, and to determine the correlation between changes in the microbiome and human health.”

Unfortunately, this multimillion-dollar effort does not extend to the surface of the eye. Therefore, in 2009, researchers at the Bascom Palmer Eye Institute in the USA initiated the Eye Microbiome Project.

It was once believed that the surface of the eye is relatively devoid of microorganisms, thanks to tears and blinking, which “wash away” them – despite this, research by the Bascom Palmer Eye Institute established the opposite: the surface is “densely populated” not only with bacteria (about a dozen different types ), but also viruses.

“People can have very different microflora and, nevertheless, healthy eyes, which made it difficult to work, but truly exciting,” researcher Valery Shestopalov tells The Scientist magazine.

Another finding of scientists is also interesting: it turns out that with keratitis (a serious infectious disease of the cornea), only half of all types of bacteria are found.

The most represented strains of pseudomonads, and changes in the microbiome occurred long before an eye infection was diagnosed – this suggests that these changes could be used for early diagnosis of infection, and maybe someday it can be used for complete prevention of infection …

In this case, the researchers believe that contact lenses may be more susceptible to infections because the lens surface is more easily colonized by pathogens.

Individual researchers have developed antimicrobial contact lenses , which, in their opinion, will help solve the problem without affecting the normal opportunistic flora of the eye.

An imbalance in the microbial community can lead to many health problems

It is not just the eyes that can be affected by the disruption of the microbiome.

Researchers have found that microbes of all kinds play an important role in the functioning of the body.

For example, beneficial bacteria, also called probiotics, have been proven:

  • Fights inflammation and controls the growth of bacteria that cause disease
  • Produce vitamins, absorb minerals and detoxify
  • Control asthma and reduce the risk of allergies
  • Beneficial for mood and mental health
  • Normalize weight

Research now shows that the complex interactions of all these microorganisms, bacterial and non-bacterial, can literally build or destroy your health.

Researchers are actually beginning to recognize the gut microbiota as one of the underestimated “organs”.

It has even been argued that would be more appropriate to view the body as a “super-organism” composed of symbiotic microorganisms.

The beneficial nature of this symbiotic relationship goes beyond so-called “friendly” bacteria.

Even microorganisms that are generally considered “bad” or pathogenic play an integral role in maintaining health and preventing disease.

In addition:
  • Microbiota affects cancer susceptibility. Intestinal microorganisms even appear to interfere with the effectiveness of various cancer treatments
  • Microbiota affects weight. Communities of microorganisms in obese people and in thin people, as a rule, differ
  • Microbiota affects mental health. The use of certain probiotics helps to cope even with severe and chronic mental health problems, including post-traumatic stress disorder (PTSD)

If you eat too many grains, sugars, and processed foods, they become “fertilizers” for pathogens and yeasts, which help them multiply quickly.

The best way to maintain microbial diversity is to diversify your diet by including many fiber-rich vegetables and fermented foods while avoiding antibiotics.

Diet changes are known to drastically affect microbial diversity in just two weeks, but it is not known if this has an effect on the eye microbiome.

Are there other health risks from contact lenses?

The most well-known risk of wearing contact lenses is an increased infection rate.

Every year, people who wear contact lenses go to an ophthalmologist or emergency room for eye infections about 1 million times; they are often caused by improper use of contact lenses (for example, being left overnight or not properly cleaned).

Corneal erosions, corneal ulcers and even infections that can lead to blindness may develop.

It is recommended to properly clean and disinfect the lenses, each time pouring a fresh portion of the solution.

Do not pour solution up to the container lid or reuse.

In addition, contact of any non-sterile water on the lenses can cause problems, therefore it is recommended to remove the lenses before swimming and at night.

The container for storing contact lenses should be changed every three months.

In addition, contact lenses and glasses act as a filter that prevents all 1,500 wavelengths of sunlight from passing through the retina, where they are absorbed by the brain.

Constant wearing of glasses or contact lenses increases the risk of depression as it deprives the brain of many valuable frequencies of sunlight.

Improve vision through relaxation

If you choose between contact lenses and glasses, the latter will be significantly less damaging to eye health, especially when it comes to the microbiome.

But even so, if you wear glasses, you force your eyes to strain all day, which is the exact opposite of what is needed for healthy vision.

Weak eye muscles do not impair vision. They are strong enough. They are simply too tense to work properly, so you need to relax.

Bates psychological method can help with this.

The problem is, when you start wearing corrective lenses, you are actually impairing your vision.

Progressive visual impairment leads to a defeatist mood if you do not realize that you yourself are creating this problem.

Greg Marsh, Certified Natural Vision Trainer explains:

“The key word for Dr. Bates is tension. If you strain your eyes, you strain your thoughts and strain your eyes, and those muscles become tight.

Voltage is the essence of everything. Imagine that you are standing on a tightrope, walking on it and feeling your way forward.This is how the eyes want to work. If you are tense on a tightrope, you will die, right?

Instead of taking it as an exercise, be more delicate about it, because it is more like meditation. “

Think of it as an experiment where you make a tiny hole with your hands and you will be amazed at how clear your vision is without any corrective lenses.

  • Simply bend your finger to create a small opening between folds of skin.
  • Now keep this hole in front of your eye and notice how much the focus of everything you are looking at has increased.
  • Seeing is said to be believing, and it will take you a long time to make sure you can see well without corrective lenses.

Take off your glasses – it will help improve your vision

Ideally, glasses (or contact lenses) should be removed when it is safe to do so. Also, make sure that the lighting is appropriate, especially when reading.

As a rule, correction with glasses is most often required for two conditions: myopia (myopia, which usually appears in childhood or adolescence) and presbyopia (a type of hyperopia, due to which in middle age there is a need for glasses).

Both of these states respond well to the application of the Bates method, and, in both cases, this approach is almost identical.

If you have been prescribed moderate diopters, you can simply walk without glasses more often as your vision improves.

Of course, glasses should always be worn while driving until you pass your vision test without them.

One of the most famous Bates methods is palming.

  • Look around you and notice the level of clarity of vision at the moment.
  • Then just place the center of your palms over your eyes.
  • Relax your shoulders. You may want to lean over a table or lean on pillows to help you relax.
  • Sit like this for at least two minutes.
  • Now remove your hands, open your eyes and notice that everything around you seems to be clearer.

This is usually the case.

Also remember that thinking is essential . With faith in yourself and the ability of your body to heal itself, the most difficult thing is to learn to relax so that your eyes function as nature intended. Published by

90,000 Clinical Study Dry Eyes: Alginic Acid Contact Lenses, Alginic Acid Free Contact Lenses – Clinical Trials Register

This study will be conducted in accordance with protocol, SGCP and applicable regulatory requirements.

Dry eye is a condition that affects 5-35% of the population.1 Common symptoms of this condition include eye irritation, heaviness of the eyelids, blurred vision, watery eyes and photosensitivity.2 This significantly affects the quality of life and vision in dry eye syndrome In addition, there is a significant socio-economic burden: in 2009, 54,051 patients sought treatment for dry eye at the Singapore National Eye Center (SNEC). for drugs for dry eye syndrome amounted to US $ 181,354.1715. productivity that further increases the socioeconomic burden16.

Contact lens-induced dry eye (CLIDE) mimics the symptoms found in dry eye patients.reported that people who wear contact lenses are 12 times more likely to report symptoms than emmetropes. and 5 times more likely to report symptoms than eyeglass wearers. Decreased fracture times have been reported with contact lens wear, resulting in excessive evaporation, decreased tear volume, and increased osmolality. Asian contact lens wearers experienced more severe dry eye symptoms than those who did not (Lungrin et al, ARVO 2008). Reports have shown that Asians have a shorter mean tear time to tear (TBUT) and a lower tear.volume The symptom usually increases significantly during the day (Begley et al. (2000)).

Contact lens material and tear film stability remain important due to patient dryness symptoms. Lens wetting is associated with wearer comfort and disruption of the tear mechanism in the contact lens wearer reduces the stability of the tear film and thus reduces comfort levels. Evaporation of the tear film has been found to increase during lens wear. To date, silicone hydrogel lenses with surface technology that can mimic the ocular surface have proven encouraging among users.

A new type of disposable contact lens (SEED 1dayPurewater and 2 weeks clean) was developed in Japan. These are corporate factors such as high water content, zwitterionic material containing alginic acid, which acts as a moisturizing agent, high biocompatibility, which has both positive, and negative ions, which prevents pollution, UV protection and shape stability, which is suitable for patients suffering from dry eyes caused by contact lenses.

Dry eye caused by contact lenses remains a major contributor to contact lens loss. Improved lens material and replacement schedule can greatly contribute to the adoption of the Contact lens population. With the introduction of a new material for disposable contact lenses, it can significantly improve dry eye and comfort in symptomatic patients. can achieve a more successful result.

Recent technological advances as well as the infrastructure of the Singapore Eye Research Institute (proximity to the Singapore National Ophthalmology Center and an existing facility and infrastructure for clinical trials) have facilitated research into products that are available elsewhere and may benefit the people of Singapore.

Dry eyes caused by contact lenses will shorten the wearing time and eventually stop wearing the lenses. Tear resistance has been reduced in symptomatic contact lens wearers, and evaporation has been shown to increase with lens wear.

A new type of contact lens will be developed that can retain moisture in the eye. desirable in the treatment of contact lens-induced dry eye (CLIDE) to improve comfort and reduce contact lens loss.

Methods Participants and Target Sample Size Thirty people who regularly wear symptomatic contact lenses will be recruited for this study from a dry eye clinic at SNEC. randomly assigned to one of 2 treatment groups.

Healing hands:

Control: the same lens without alginic acid (n = 15), zwitterionic with alginic acid; SEEDS 1 day Pure Humidity (n = 15)

Patients will be asked to remove their usual contact lenses 2 days before the baseline visit.Wearing schedule – daily wear with daily replacement. wear contact lenses every day for 7 days of the study, at least 8 hours a day, and be asked not to sleep with contact lenses.

Schedule of visits There will be 3 study visits in total, including a screening visit that will take place at a regular dry eye clinic. Basic visit. The follow-up visit will be on days 7 and 8. Window A period of +/- 2 days is allowed for this exploration.

Duration of training:

Seven days.

Primary Outcome

• Visual analogue scale (VAS) difference for eye discomfort between control and treatment group.

VAS will be used to assess dry eye symptoms as described by Schaumberg et al. (Schaumberg, Gulati et al., 2007). Points will be recorded separately for the frequency and severity of dry eye symptoms. The patient will be asked to check a point on the 100 mm line. which corresponds to the degree of the symptom. the location of the mark made by the patient for each question will be measured in mm from the left side of the 100 mm line and recorded in mm.For subsequent visits, during which the distance between the marked marks is measured. patient and center anchor, a negative value will be recorded if to the left of the anchor and a positive value to the right of the anchor.

The total score will be calculated by multiplying the frequency score by the severity score. and extracting the square root of the result (to revert to the original scale).
