Details:

Photochromic lenses are eyeglass lenses that are clear (or nearly clear) indoors and darken automatically when exposed to sunlight. Other terms sometimes used for photochromic lenses include "light-adaptive lenses" and "variable tint lenses."

What is the photochromic lens?
 

Photochromic lenses typically will not darken inside a vehicle because the windshield glass blocks most UV rays.

Why do we wear the photochormic glass?
