ZEISS Photofusion

PhotoFusion by ZEISS — Fast dark. Fast clear.
Fast reaction — for more convenience.
PhotoFusion lenses adapt quickly to changing light conditions. The high- and mid-index react up to 2x faster from dark to clear, and up to 20% faster from clear to dark than previous photochromics from ZEISS.

100% solar UV protection — for full protection.
The secret behind PhotoFusion is photo-active molecules that respond more efficiently to light energy. Solar UV rays activate the self-tinting process. The stronger the solar UV rays the darker the photo active molecules tint the lens. Without exposure to solar UV ray the moles stay compact. When exposed to strong UV rays, the molecules fully open for an optimal dark tint.

Benefits for the wearer
- Convenience
- PhotoFusion lenses adapt to changing light fast for more convenience in everyday use.
- Comfortable vision
- PhotoFusion lenses are very clear indoors yet turn very dark outside in sunlight for excellent vision at all times.
- Protection
- PhotoFusion lenses provide 100% protection against harmful solar UV rays.
- Durability
- PhotoFusion lenses retain their self-tinting performance longer.
- Color Consistency
- PhotoFusion lenses show excellent color consistency for an attractive appearance in any lens state.



PhotoFusion – a technical innovation
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.
