Photochromic lenses change color in the sunlight. Typically, they are clear indoors and at night and change to grey or brown when exposed to direct sunlight. There are other specific types of photochromic lenses that never turn clear.

2) Outstanding Color Performance

◆ Fast speed of changing, from white to dark and vice versa.
◆ Perfectly clear indoors and at night, adapting spontaneously to varying light conditions.
◆ Very deep color after change, the deepest color can be up to 75~85%.
◆ Excellent color consistency before and after change.

3) UV Protection

4) Durability of Color Change

Photochromic molecules are equally bedded in lens material, and are activated year by year, which ensure durable and consistent color change.
