ZEISS PHOTOCHROMIC LENSESPhotoFusion® by ZEISS
PhotoFusion lenses clear up to twice as fast and darken up to 20% faster than previous self-tinting offered by ZEISS*. They are very clear indoors (92% transparency with antireflective coating) and very dark in sunlight (11% transparency with antireflective coating). PhotoFusion lenses provide 100% protection against UV rays up to 400 nm and excellent color consistency for natural vision. They also retain their selftinting ability for the life of the prescription (2 years).
The innovative PhotoFusion technology is based on patented photoactive molecules that unfold when exposed to UV light, thus darkening the lens and providing UV protection. Combined with award-winning ZEISS lenses, this technology is a significant improvement on the basic principle of photochromic eyeglass lenses.
