General
Photochromic lenses are lenses that get darker the more light there is. The lighter it is, the more your optical glasses turn into sunglasses. Some lenses only darken when outdoors, others will darken indoors as well. Learn about the different options below.
These photochromic lenses are available in most single-vision and progressive lenses or bifocals. Would you like to learn more about these lenses? Go to the section on single-vision and/or progressive lenses to see the difference between the various types of single-vision and progressive lenses.
