On bright sunny days and even on rainy ones – our eyes are exposed to UV rays during the day time. Many people do not even know that this exposure is not only damaging for the skin, but also a risk for the eyes. PhotoFusion lenses provide 100 percent protection.
For most people it has become a habit they take for granted – on sunny days, they put on sunscreen to protect their skin from damaging UV rays. However, many of us forget that we need to protect our eyes as well. UV-A and UV-B rays do not only attack the skin, but also our vision.
Recent research confirms it: If we expose our eyes to dangerous rays for extended periods of time, we put ourselves at risk of developing vision problems and even diseases such as cataracts and macular degeneration (this illness impairs the vision in the central facial area as a result of killing off retina cells). Even the eyes can get sunburned; a condition experts refer to as photokeratis. What can we do to protect our eyes? As sunscreen is not available, we have to wear lenses that protect our most important sensory organs.
Of course there are also differences in quality amongst self-tinting lenses. The so-called photochromic lenses are also available in ZEISS quality: PhotoFusion®. They have a photosensitive coating and offer eyes the best protection. Thanks to the use of patented photoactive colour molecules, PhotoFusion® self-tinting lenses are, above all, fast in darkening and clearing.
As soon as the UV rays of the sun hit these special lenses, they are activated and darken. Once the sunlight’s intensity declines, the glasses begin to clear.
One of the special features of the PhotoFusion® lens: The shading adjusts to changing outdoor light conditions consistently and ensures that the perfect amount of light reaches the eyes. Depending on your individual needs, you can also choose from colour options in brown and grey. The best piece of news: Regardless of how clear or dark these special transitions lenses get, they always block out 100 percent of the damaging UV-A and UV-B rays. The self adjusting effect works so quickly and consistently that most people who wear these glasses do not even notice the changes.
More good news: PhotoFusion® lenses fit almost all spectacle frames and are normally available with all ZEISS lens/coating features and technologies. And it doesn't matter whether you choose single vision lenses, progressive lenses or special plastic lenses (also for thin and light glasses), the right self-tinting lenses are available for them all. The best thing to do is to talk to your optometrist.
