Many people wind up with two pairs of eyeglasses -- a pair of prescription lenses for indoors, as well as a pair of prescription sunglasses for outdoors -- which they swap out depending on the environment.

Photochromic lenses are eyeglass lenses that darken automatically when exposed to sunlight and fade back to clear when you return indoors. In most cases, photochromic lenses are clear (or nearly clear) indoors and darken to a medium tint outdoors.
