Photochromic Grey Vs Brown

Transition lenses react to UV exposure (and, in some cases, ambient/available light) and darken, or lighten, depending on the lighting conditions. When inside, or during the night, the lenses will undoubtedly be within their default, non-activated state. This seamless process from clear to dark makes transition glasses one of the convenient and versatile eyewear choices. Photochromic lenses darken in bright sunlight, so their color hue and depth changes based on sunlight conditions. Some photochromics may appear to have a slight base tint, or may develop one after prolonged use.

In the absence of activating light, the lenses return to their clear state. Photochromic lenses could be made of glass, polycarbonate, or another plastic.
