Photochromatic/PhotoGrey Lens
Photochromic lenses darken to a sunglasses tint when exposed to sunlight, or UV ultraviolet, and return to a clear state when indoors, away from UV light.
They are typically used as sunglasses that conveniently switch from a clear lens indoors to a sunglasses depth tint when outdoors and vice versa.
They typically take around 30 seconds to fully darken and between two to five minutes to return to a clear state.
Advantages:
