Up to 40 percent of eyeglass wearers are interested in self-tinting lenses, according to an international Carl Zeiss Vision study of 5,800 eyeglass wearers. Yet despite high consumer interest, only about 20 percent of eyeglass wearers purchase self-tinting lenses. Many consumers hold back because they want lenses that darken and clear faster. To meet this need, ZEISS, a leader in precision optics for over 160 years, has introduced a new self-tinting lens called PhotoFusion®.
PhotoFusion® lenses darken and clear faster than previous self-tinting lenses offered by ZEISS. PhotoFusion technology is based on patented photoactive molecules. When exposed to UV light, the molecules change configuration and absorb light, creating a sunglasses tint. In the absence of UV light, the molecules return to their original state and the lens becomes clear again. The molecules used in PhotoFusion lenses react more efficiently to changes in UV conditions, resulting in increased darkening and fade-back speed. Additionally, PhotoFusion lenses block 100 percent of harmful UV rays, whether they are tinted or clear.
"Carl Zeiss Vision has been a driving force in the science of vision for over 160 years," said Dr. Raymund Heinen, CEO, Carl Zeiss Vision. "We are continuously striving to offer high-quality products and services to protect human vision and optical health and thus increase quality of life. We are incredibly pleased to make life a little easier for wearers of glasses and sunglasses with PhotoFusion."
