What Are Photochromic Lenses?
Photochromic lenses, also known as light-adaptive or light intelligent lenses, are eye glass lenses that are clear when you are indoors but darken automatically when you go outside.

You can find photochromic lenses in nearly all lens materials and designs, including progressive lenses, bifocals, and high-index lenses.
