Photochromic glasses have lenses that change tint depending on the weather or surroundings. The benefit of photochromic lenses is that in dull, overcast weather or darker surroundings (like running or cycling through woods or early / late in the day) they will lighten. But in bright, sunny conditions they will go dark. Photochromic lenses are most popular with cyclists, runners, skiers, tennis and outdoor reading enthusiasts.
Photochromic Lenses are clear when indoors or at night and automatically darken to a gray lens sunglasses tint when exposed to UV sunlight.
Photochromic lenses are transformed from indoor reading glasses to outdoor reading glasses. They can also be used as ordinary photochromic sunglasses with UV protection.
They are an excellent solution for people who hate constantly switching between their reading glasses and their shades
