Understanding Reversible Sunglasses by ARCUS is a document available to read on EtoBox.

Visitors will learn how photochromic lenses work on a molecular level. Photochromic molecules change shape when exposed to UV light, causing the lens to darken. The molecules flatten out when hit by UV rays, allowing electrons in the molecule to absorb visible light. When UV light is removed, the molecules return to their original folded shape and the lens becomes clear again. Sample chips demonstrate that photochromic dyes come in different colors. Understanding molecular switches could help mimic function
