The all new ZEISS Photofusion X Black is now available and in multiple indexes including 1.74 highest lens index, suitable for high prescription spectacle wearer.

On October 2024, we at Malaya Optical were invited to attend the Zeiss Innovation Summit at Le Meridien. They introduced several newly launched products which were very fascinating, one of them being Photofusion X Black.
What is Photofusion X?
Photofusion X is a photochromic technology that turns clear lens to sunglass-level darkness outdoors. It also comes with built-in blue light and UV protection. As a result, it blocks up to 50% blue light indoors and up to 94% outdoors when fully tinted. Furthermore, a wide range of photochromic lens colours are available for you to match with the frame of your choice. Photofusion X only takes 15 seconds to turn dark, up to 60% faster than before, and turns clear up to 2.5 times faster.

Photofusion X Black
Now with the new colour – Black, an independent study shows that it can go up to 20% darker than Photofusion X Extra Grey, 14% darker at high temperature. The test was conducted in countries with high UV level. It also blocks up to 52% harmful blue light indoors and up to 96% when fully dark outdoors.


ZEISS Photofusion X Black provide extra darkness designed for very hot climate. It has excellent colour consistency in a neutral, blackish, grey. The term “photochromic” comes from the Greek words phos (= light) and chroma (= colour). The secret behind ZEISS PhotoFusion X Lenses are photo-active molecules which react quickly to changing light. The new speed-optimised carrier matrix gives the molecules more freedom to quickly fold or unfold at their maximum level of performance.
The new improved, faster dye compounds (each less than 0.3mm in diameter), need very little light energy to react. When the intensity of UV changes, molecules undergo a change process that causes lenses to darken or clear up. Thanks to an innovative way of combining these molecules with ZEISS lenses, it has been possible to design the next generation of powerful self-tinting lenses.
