This lens treatment enables eyeglass lenses to darken automatically in response to the sun's UV and high-energy visible (HEV) light rays, and then quickly return to clear (or nearly clear) when indoors. Photochromic lenses are available in virtually all lens materials and designs.
Photochromic lenses are self-tinting lenses that change from clear-to-dark and back in varying light conditions.
Patients benefit from sunglass-level UV protection and tinting to suit the changing environment they find themselves in throughout their day. With ZEISS photochromic sunglasses, switching between pairs of glasses is a thing of the past. These lenses adapt quickly to changing light conditions. They darken very fast and fade back to clear up to 4.5 times faster than the most common photochromic brand’s. These self tinting lenses offer powerful photochromic lenses for improved vision and more convenience.
Polarized sunglasses have been popular for years with boaters and fishermen who need to reduce reflected glare from the water surrounding them. But now that many others who spend time outdoors have discovered the benefits of polarized lenses, interest in these types of sunglasses has soared.
Besides boaters, outdoor enthusiasts who benefit the most from polarized sunglasses include skiers, bikers, golfers, and joggers since all of these activities require the elimination of glare for optimum safety and performance.
Polarized sunglasses can be helpful for driving, too, because they reduce glare-causing reflections from flat surfaces, such as the hood of the car or the road's surface.
Some light-sensitive people, including post-cataract surgery patients and those continually exposed to bright light through windows, may also choose to wear polarized sunglasses indoors.
It is well known that sunlight contains ultraviolet radiation that damages the skin. However, few people know that UVA and UVB rays are also harmful to the eyes. These invisible rays can penetrate the eyes where, in the worst case, it can cause photokeratitis. This fortunately rarely happens, but it does not make wearing suitable glasses any less important.
When looking into sunlight, visibility is often compromised, which can be dangerous under certain conditions. Direct sunlight and changing light conditions can also be challenging. Sunglasses with special sun protection lenses or outdoor lenses will help to squint less, and can possibly reduce tearing. Eyewear with tinted lenses is also a must-have fashion accessory for many.
Natural light travels in all directions, so it’s described as "unpolarized". On a regular (unpolarized) surface, light rays have a tendency to reflect in various directions, resulting in perceived glare. Polarized sunglasses however, ensure reflected light rays are directed in a single direction, usually horizontally. As a result, distracting and potentially dangerous reflections are eliminated by polarized lenses. It improves the overall perceived quality of vision. Polarized sunglasses provide comfortable vision without distracting glare whether you are driving, spending time at the ocean or out in the snow. ZEISS Polarized Lenses provide full brilliance and vibrancy of the colors. It also offers maximum protection against potentially harmful UV light.
