What's New in Contact Lenses
Dailies AquaComfort Plus Now in Astigmatism
and Multifocal Versions
April 2014 Alcon Laboratories has expanded its Dailies AquaComfort Plus daily disposable contact lens portfolio to include toric lenses for astigmatism and multifocal lenses for presbyopia.
Like the company's core Dailies AquaComfort Plus lenses, the new lenses correct a wide range of nearsightedness and farsightedness and are designed to be discarded after a single use.
The toric lenses correct up to -1.75 diopters (D) of astigmatism, and the multifocal lenses are available in designs to correct low, medium and high amounts of presbyopia.
The new lenses are available immediately from eye care practitioners who offer Alcon contacts.

Will Antimicrobial Coatings Reduce Contact Lens Infections?
November 2013 Researchers at the Brien Holden Vision Institute and School of Optometry are working on an antimicrobial coating that might reduce inflammation and infection that can occur with contact lens wear.
The coating uses a peptide called melimine, which has proven to be effective against various pathogens including bacteria, fungi and Acanthamoeba.
The coating is heat stable and does not alter the physical dimensions of contact lenses. Additionally, the coating is wettable, but not toxic to mammalian cells.
The risk of infection with contact lens wear is rare. It occurs in only four in 10,000 daily wear and 20 in 10,000 extended wear contact lens users annually. However, severe infections can lead to vision loss.
New Travel Size for Unique pH Contact Lens Solution
September 2013 Unique pH multipurpose contact lens solution by Menicon now comes in a two fluid ounce bottle, which meets TSA guidelines for carrying liquids on board aircraft.
The bottle incorporates the latest Blow-Fill-Seal technology, so the dropper tip is sealed to provide extra insurance against the unopened bottle leaking during a flight.
To unseal, just screw the cap clockwise as far as it will go, and it will pierce the seal.
The travel pack also includes a lens case, and it is available on the Menicon webstore (soon to be on Amazon.com and Drugstore.com as well).
To find out if Unique pH solution is appropriate for your contact lenses, ask your eye care practitioner.
1-Day Acuvue TruEye Now Available in New Material and Additional Base Curve, to Fit More People
July 2013 1-Day Acuvue TruEye Brand Contact Lenses has been relaunched in the United States in a new material and an additional base curve.
The material, narafilcon A, is designed to help maintain the natural ocular environment, allowing it to offer exceptional comfort, according to manufacturer Vistakon, a division of Johnson & Johnson Vision Care.
In a recent 74-subject study, the lenses were found to have no clinically significant effect on the ocular surface of the eye as compared with non-contact lens wearers across five of six contact lens-related measures associated with eye health. The lenses also provided high levels of comfort from morning to night, comparable to wearing no lenses at all.
Other features include 100 percent corneal oxygen consumption at all points for healthy eyes and the highest level of UV protection in a contact lens, according to Vistakon. In fact, the lens blocks about 96 percent of UVA rays and more than 99 percent of UVB rays that reach the lens.
With two base curves (8.5 and 9.0), more people can now be fitted with 1-Day Acuvue TruEye than ever before. Ask your eye care practitioner about 1-Day Acuvue TruEye (narafilcon A), which comes in 90-packs.
Contact Lens Wear Linked to Higher Self-Esteem in Children
July 2013 Children who wear contact lenses to correct nearsightedness exhibit higher self-esteem both before and after they begin contact lens wear, compared with those of the same age who wear glasses, according to a new study.
Researchers at Stony Brook University School of Medicine (New York) used standardized tests to evaluate the self-esteem of 423 myopic children ages 12 to 17, six years after they had enrolled in the Correction of Myopia Evaluation Trial (COMET).
The COMET study was designed to evaluate the effect of wearing progressive eyeglass lenses vs. regular (single vision) eyeglass lenses on the progression of nearsightedness in children over a period of at least three years. Five years after enrollment in the COMET study, participants could choose to continue wearing eyeglasses or be fitted with contact lenses.
At the six-year follow-up visit when self-esteem data were gathered, the mean age of the study participants was 15.3 years, and the mean amount of nearsightedness was -4.6 diopters (D).
Not all teens are good candidates for contact lenses. But for those who are, higher self-esteem could be a benefit.
In addition to using standardized self-esteem tests, the researchers also evaluated self-reported measures of self-esteem by the study participants in several areas: scholastic/athletic competence, physical appearance, social acceptance, behavioral conduct and overall feelings of self-worth. Results were compared with baseline self-esteem scores recorded prior to contact lens wear.
Results revealed that children who chose to wear contact lenses after five years of wearing glasses during the COMET study had higher social acceptance, athletic competence and behavioral conduct scores at baseline compared with eyeglass wearers. One year later, the contact lens wearers continued to report higher social acceptance scores after adjusting for baseline scores and other variables.
The study authors concluded that children who chose to wear contact lenses after five years of wearing eyeglasses for myopia correction had higher self-esteem both before and one year after initiating contact lens wear compared with children who continued to wear eyeglasses. The results of the study also suggest self-esteem may influence the decision by children to wear contact lenses, and that contact lens wear in turn is associated with even higher self-esteem among children most likely to wear them, they said.
The study report appeared on the website of the journal Ophthalmic & Physiological Optics in June.
Dailies Total 1: Innovative "Water Gradient" Contact Lenses
July 2013 Dailies Total 1 are the first and only water gradient lenses, says manufacturer Alcon, and are the result of more than a decade of product development. The daily disposable soft lenses feature an inner core that is 33 percent water, and the water content increases to more than 80 percent at the front and back surfaces of the lenses.
This water gradient design significantly increases the wearing comfort of the lenses, with nine of 10 wearers surveyed reporting the lenses were so comfortable they had no awareness of having a contact lens on their eye.
Dailies Total 1 lenses also have the highest surface lubricity (slipperiness) tested and the highest breathability of any daily disposable contact lens on the market, according to the company.
Currently the lenses are for nearsightedness only, in powers ranging from -0.50 to -10.00 diopters. In the near future, Dailies Total 1 lenses also will be available for farsightedness and astigmatism. The lenses are for one-day use only and come in boxes of 30 or 90 lenses from eye care providers nationwide.
"Survival Guide" Offers Tips for Getting Through the Allergy Season
April 2013 If you're a contact lens wearer who suffers from eye allergies, watch this new video by contact lens manufacturer CooperVision.
Called "Helping Deal with Allergies While Wearing Contacts," the video provides tips for dealing with this season's itchy, burning, watery eyes.
The company also offers eye allergy fact sheets, allergy survival tips, access to The Weather Channel's Allergy Index and more videos about eye allergies.

Contamination of Daily Disposable Contacts When Re-Used
February 2013 Do you ever store your daily disposable contacts in their packaging and then use them again the next day? If so, you're risking an eye infection.
In a study, 20 people wore their daily disposables for one day, then stored them overnight in the original blister pack solution, covered with the original packaging foil.
The next morning they used new plastic forceps to transfer the lenses and solution to a new contact lens case, which was submitted to a lab. The participants did this on five occasions within a month.
The lab compared the 200 samples with a control group of new daily disposable contacts and packaging solution.
The lab found that 45.5 percent of the samples had growths in the solution, and 21.5 percent of these had Staphylococci, while 28 percent had gram negative rods. For 95 percent of the participants, at least one pair of contact lenses was contaminated, and for 35 percent, all samples were contaminated.
The study appeared in Optometry and Vision Science, volume 88, issue 12.
FDA Warns Against Improper Use of Special-Effect Contact Lenses
October 2012 Special-effect contact lenses can put the finishing touch to your Halloween or other costume-party attire, but it's definitely not worth losing your sight over.
The FDA has released a consumer update video on the dangers of wearing special effects contact lenses when not properly prescribed by an authorized eye care practitioner, not properly worn and cared for, and purchased from an illegal source.
Improper use of contact lenses can result in serious eye infections, eye abrasions, vision problems and even blindness. To help minimize the risk, visit your eye doctor for a contact lens exam, fitting and prescription before purchasing any contact lenses even if they are non-prescription lenses.
Always follow your ECP's instructions for wearing and caring for your decorative contact lenses. And remember to never share your contacts; doing so could result in serious damage to your eyes, including loss of vision.
Bausch + Lomb To Launch Biotrue OneDay Disposable Contact Lenses
July 2012 If you have blurred vision at the end of your workday, it may be because your contact lenses are losing moisture, which changes their shape and reduces clarity of vision. Biotrue OneDay lenses are a new option to combat this problem.
Manufacturer Bausch + Lomb says the product is a premium daily disposable lens made from a bio-inspired material called HyperGel that helps retain moisture and the proper optical shape of the lens, even after hours of wear.
The company maintains that the material has the best features of both conventional hydrogels and silicone hydrogels, as it contains 78 percent water (the same water content as the cornea) and delivers the oxygen needed by the open eye to maintain healthy, white eyes. And the outer surface of the lens is similar to the lipid layer in the eye's tear film, to prevent moisture loss.
Biotrue OneDay just received FDA approval and will be available in the United States this month. The company also makes Biotrue multi-purpose contact lens solution, which debuted in 2010.
Eye Comfort and Wearing Time May Improve When You Wear Daily Disposable Contact Lenses
May 2012 If you're having problems with contact lens wear, there's a good chance that switching to daily disposable lenses will clear them up.
A recent study included 316 reusable contact lens wearers who were having eye problems (dryness, irritation, discomfort, redness, etc.). Once they were refitted with daily disposable lenses, the prevalence of dryness fell by 19 percent, and the uncomfortable wearing time fell by 35 percent.
The study was supported by funding from Johnson & Johnson Vision Care, the makers of Acuvue contact lenses.

Proclear 1 Day Multifocal Now Available
May 2012 Most eye care professionals agree that daily disposable contacts provide the healthiest way to wear contact lenses. Now people with presbyopia have a new daily disposable lens option in Proclear 1 Day Multifocal.
The lenses have a center-near aspheric design and come in a broad power range (+6.00 to -10.00 diopters of sphere). They can help people who need up to +2.50 diopters of reading power.
And they are made of the only lens material that has received FDA approval to claim it "may provide improved comfort for those who experience dryness or mild discomfort during lens wear." This is important for older wearers, who often experience eye dryness.
Ocusoft Debuts Hydrogen Peroxide Contact Lens Cleaner
May 2012 The new Ocusoft Lens Care System is a preservative-free cleaning system for soft contact lenses.
It uses hydrogen peroxide for deep cleaning, removing protein and deposits from lenses. The manufacturer says it also increases comfort with an added lubricant.
In a recent independent study, it was more effective than two-step peroxide, multi-purpose and saline solutions.
Ocusoft Lens Care System is sold through eye care professionals only. Please click here for a closeup image and results from the study.
1-Day Acuvue Moist Contact Lenses for Astigmatism Debut
April 2012 Now 1-Day Acuvue Moist contact lenses come in a toric design for people with astigmatism.
The daily disposable lenses have what Acuvue calls a proprietary Blink Stabilized design, which takes advantage of the natural pressures of blinking eyes to keep the lenses in place and realign them quickly if they rotate. This is important, to keep vision consistently in focus all day.
Made with Lacreon Technology, the lenses have an embedded ingredient designed to maintain moisture all day, to combat dryness and discomfort. They are available in 12 axes and four cylinders, at distance powers of +4.00D to -9.00D. And they block about 82 percent of UV-A and 97 percent of UV-B radiation (though they should be used in conjunction with UV-blocking sunglasses when outdoors).
