Bausch + Lomb Launches PureVision2 HD for Astigmatism
October 2011 New PureVision2 for Astigmatism contact lenses were designed with what Bausch + Lomb calls High Definition Optics, to provide crisp vision for people with astigmatism.
The toric lenses have a stabilization system called Auto Align Design, to help the lenses stay in place without rotating. (Rotation of a lens on the eye is often the reason for blurry vision in astigmatic wearers.)
At 14.5 mm, the lens diameter is large, which is also meant to prevent rotation and keep the lenses centered on the eyes.
- Wear contacts overnight, see clearly during the day with Paragon CRT
- Hassle-free contact lens care for RGP and soft contact lenses from Lobob
- About the LASIK experience: before, during and after laser eye surgery surgery
For comfort, the lenses are thin with unobtrusive edges, are highly oxygen-transmissible and come in a moisture-rich packaging solution. The company also says that PureVision2 HD for Astigmatism reduces spherical aberration to help reduce glare and halos in dim lighting.
Duette Multifocal Now Widely Available for People With Presbyopia
August 2011 A nationwide rollout of the Duette Multifocal hybrid contact lens began this month. This is a multifocal lens that has a gas permeable center for crisp optics and a soft, silicone hydrogel skirt for comfort on the eyes.
Made by SynergEyes, the Duette Multifocal has a simultaneous vision design. The idea is to provide true binocular vision at all distances, with progressive vision correction that the company says resembles that of progressive eyeglasses.
Best Way To Clean Contacts Is the "Rub and Rinse"
Method, Says Study
August 2011 If you use a "no-rub" multipurpose disinfection solution to clean your contact lenses and you're not rubbing the lenses, you may be leaving germs behind.
A study of popular multipurpose disinfection solutions revealed that, regardless of lens type, manually rubbing the lenses under a steady stream of fresh solution for several seconds, then storage in fresh solution, killed the most bacteria, fungi and Acanthamoeba microorganisms. Just rinsing without rubbing didn't work as well. And just removing the lenses and putting them in fresh solution without rinsing was the least effective method in the study.
Microorganisms do adhere to lenses, and the only sure way to remove most or all of them is to rub the lenses, especially when the contacts are made of a silicone hydrogel material.
A report on the study appeared in the August issue of Optometry and Vision Science.
Lenstoss iPhone App Helps Contact Lens Wearers Stick to Their Lens Replacement Schedule
May 2011 We contact lens wearers have all done it at least once: worn our disposable lenses for longer than our eye doctor prescribed.
Why? Because we just plain forgot what day we were supposed to throw them out.
But we pay a price for our forgetfulness, with red, itchy, dry eyes and blurry vision from all the proteins and other debris our lenses will inevitably collect over time, no matter how well we clean them.
In fact, overwearing lenses can result in a nasty eye infection or even scarring on the eye's surface.
Lenstoss, an app for the iPhone, iPod Touch and iPad, gives you all kinds of power to overcome your forgetfulness. Lenstoss was developed by an optometrist, Troy Flax, OD who, during two decades of eye care practice, has seen it all and knows what we contact lens wearers need to keep our eyes healthy.
Here's what Dr. Flax designed Lenstoss to do:
- Tell you that it's time to replace your contacts one, two, and/or three days ahead, as well as on the replacement day itself.
- Remind you the day after, too.
- Show how long you've been wearing your current pair of lenses.
- Click through to your lens manufacturer's website to see their current coupons and rebate offers.
- Email your eye doctor that it's time for you to re-order.
- Remind you that it's time for an eye exam.
- Show you links to sunglass and contact lens solutions websites.
- Show you links to other money-saving eye-related coupons.

Tissue-Wiping Your Contact Lens Case May Keep
More Bacteria Off Your Lenses
May 2011 If you're a contact lens wearer, you probably know there's more you could be doing to clean your contacts to avoid an eye infection. But have you considered wiping the storage case with a tissue after removing the lenses?
Scientists at Brien Holden Vision Institute checked the effectiveness of four different contact lens cleaning regimens against bacteria biofilm formations on unused contact lens cases. The tests used two different multipurpose disinfecting solutions or distilled water.
The four regimens were:
- Rinse and air-dry
- Rub, rinse and air-dry
- Tissue-wipe and air-dry
- Rub, rinse, tissue-wipe and air-dry
The "rub, rinse, tissue-wipe and air-dry" method removed the most bacteria from the cases. Also, more bacteria were removed from cases without ridges inside than from cases with ridges.
A report of the study appeared online in April in the journal Investigative Ophthalmology & Visual Science.

Automatic Reminders Really Do Help Contact Lens Wearers
Replace Their Lenses on Time
February 2011 In a survey, 95 percent of 700 users of the Acuminder service said the reminder tool helped them remember to change their lenses, and 66 percent said it has improved their contact lens replacement.
Acuminder is a free online tool that Vistakon, maker of Acuvue contact lenses, launched in 2007. Any contact lens wearer even those who don't wear Acuvue lenses can use it to set up reminders for changing contact lenses, ordering new ones and scheduling regular eye exams. The reminders can be in the form of emails or text messages.
Another interesting survey finding is that before enrolling in Acuminder, only 40 percent of those wearing two-week lenses said they changed their lenses at or less than 14 days. In fact, the average wear time in the two-week group was 19.9 days.
But since using the reminder, 76 percent said they now change their lenses at or less than 14 days. The average wear time dropped to 14.7 days.
Adherence to a proper schedule of lens replacement and eye exams is very important for contact lens wear, to reduce the potential for discomfort, eye infections and other problems.
Duette Hybrid Contact Lenses Now Available Nationwide
January 2011 Duette toric lenses for astigmatism are now available across the United States, after a limited launch a few months ago by manufacturer SynergEyes.
These lenses contain MaxVu rigid gas permeable material in the central area, for crisp visual acuity; the material also contains a UV light blocker. A soft Flex2O silicone hydrogel skirt surrounds the gas permeable material, for comfort and ease of insertion and removal.
Duette is rotationally symmetric and corrects astigmatism without inconsistent axis shifting problems of some other toric lenses.
Duette fits a great variety of people, as it is currently available in powers of +4.00 to -12.00 diopters, in five base curves and three skirt curves. It will also correct up to 6.00 diopters of astigmatism.
