![]() ![]() That way you are sure to have it decompose completely (to water and oxygen) in a predictable time. So, the hydrogen peroxide does a fine job of cleaning contacts, but they are intentionally making the peroxide break down. Okay, so there’s the deal: after 6 hours the peroxide will be water + oxygen. The directions say to use the special lens case that comes with the solution and to leave your contacts in there for at least 6 hours. Ah ha! So, that is what that brown-colored plastic at the bottom is! Talked to a very nice customer service representative who told me that part of the lens case is platinum coated to make the peroxide break down. Then again, there is a part that is brown, but it felt like plastic. (That was my thinking.) (A number of different metals are hydrogen peroxide catalysts - things that make peroxide break down more quickly.) Or some other kind of catalyst?īut nothing in there really looked like metal to me. It started to dawn on me that the “special case” must have some kind of metal in it to make the hydrogen peroxide break down. The directions say NOT to use the solution in a regular “flat” contact lens case.Īfter I’d done it wrong (using a regular case with their solution) and I’d burned my eyes (you have to rinse off hydrogen peroxide really really really well if you do it wrong), I went back and re-read the directions. The interesting twist is that Clear Care comes with a little contact lens case, which you are told to use with the solution. (It can damage your corneas, plus it huurrrrrts.) NEVER put hydrogen peroxide in your eyes. I mean, it is great for dentures and retainers and mouthwash and cleaning toothbrushes – isn’t that a bit like cleaning contacts? So, when I found a commercial product using peroxide I thought “ah ha”!īut, as you may also know, putting hydrogen peroxide in your eyes is a huge “no no”. ![]() I have to start by saying I have wondered at times if hydrogen peroxide would make a good cleaner for contacts. Thinking about Hydrogen Peroxide as a Contact Lens Cleaner This is an interesting situation, so hang on with Know that there is a commercial hydrogen peroxide contact solution? There is.ĬIBA Vision Clear Care cleans contact lenses with hydrogen peroxide. We are hoping to see these lenses available in our office later this fall, and can't wait to see the results.Okay, peroxide researchers, and consumer product super-sleuths: did you Another plus? The lens has an 8.5 base curve, whose closer fit to the eye can offer better initial comfort to the average myopic lens wearer with steeper corneal curvature. The theory is that if the contact lens and the cornea have the same water content, there will be less drawing of water from the eye into the lens, meaning better end of day comfort. ![]() At the surface of the lens, the water content reaches 80%, which matches the water content of the cornea. The solution? The water content of the lens increases gradually towards the front and back surface of the daily lens. But this relatively low water content would have meant questionable comfort as the lens drew water from the eye during the course of the day. At the central core the lens has only a 33% water content, allowing for record high oxygen transmissibility (a stunning 156 Dk/t!). The daily is made from a new silicone hydrogel material called delefilcon A. What makes the new DAILIES TOTAL 1 product different? Ciba reports that this lens is the first "water gradient" technology on the market. For contact lens wearers suffering from dry eye, the new daily materials offer a reason to hope! We are merely months away from the American launch of another new daily disposable product, this time courtesy Ciba Vision! Daily disposable products are the major forces on company's pipelines these days, with Bausch and Lomb's new Biotrue daily launching earlier this year, and Cooper Vision's Proclear 1-Day Multifocal launching last fall. The product has launched in Europe, but not yet in America. ![]()
