Photochromic glasses have an automatic tinting feature. When there is bright light like outdoors, they darken. When the light is less, they return to clear.
The great thing about photochromic glasses is you never need to take them off and risk loss or breakage. 'Transitions' is a popular brand of photochromic lenses.
