ZEISS PhotoFusion lenses, are the authomatic darkening lenses that rapidly react to variations of brightness. Discover why choose photochromic lenses PhotoFusion:
- Fast reaction – for more comfort: PhotoFusion lenses rapidly adapt themselves to variations of brightness . lenses with high or medium index get darker up to 20% more rapidly and get brightened the double more rapidly than the traditional photochromic lenses ZEISS.
- 100% UV protection– for an optimal protection : PhotoFusion lenses offer a 100% protection against UV rays- up to 400 nm.
- Excellent color uniformity – for a natural vision :PhotoFusion lenses with authomatic darkening to high and medium index show an excellent color consistency
Fast reaction to solar UV rays
the secret of PhotoFusion lenses with authomatic darkening to high and medium index are the photoactive molecules that respostd more effectively to the birght energy getting darker up to 20% more rapidly than the traditional photochromic lenses ZEISS and getting brightened up to 2 times more rapidly. Solar UV rays activate the process of authomatic darkening : he more the solar radiation is intense, the more will be the darkening of lenses , made by photoactive molecules. If lenses are not exposed to intense solar rays, molecules remain compact. When exposed to Uv solar rays, the molecules open widely and react the maximum level of darkening.
