The secret behind PhotoFusion technology is patented photo-active molecules that respond more efficiently to light energy, darkening up to 20 % faster* than existing photochromic lenses by ZEISS and fading up to 2x faster*. By combining these molecules with lenses by ZEISS, it has been possible to design a new generation of powerful self-tinting lenses: ZEISS PhotoFusion.
A new level in wearing comfort
PhotoFusion lenses by ZEISS incorporate the most important features customers expect from self-tinting lenses. They represent another step forward in wearing convenience and comfort while ensuring that wearers can trust the high quality of a ZEISS product at the same time.
UV radiation & molecules
Self-tinting lenses contain molecules that react to UV rays. When hit by UV rays, these molecules are unleashed, thus darkening the lens – the more intensive the UV rays, the darker the lenses. Self-tinting lenses therefore adjust automatically to changing light conditions. And of course, whether the lenses are clear or dark, PhotoFusion always provides 100 % solar UV protection.
