What are photocromic lenses?

Photochromic lenses are equipped with advanced light-reactive technology that intelligently adjusts to changing light conditions, ensuring optimal clarity and eye protection throughout the day.

These lenses feature a remarkable ability to darken almost instantly when exposed to sunlight, efficiently filtering out harmful high-energy blue light (400 to 420 nm) while maintaining exceptional transparency indoors. When outdoors, the grey lenses darken to block up to 91% of the harmful blue light, and the brown lenses block an impressive 90%, shielding your eyes from its potential negative effects.
