There are uv rays in the room, but the eye doctor points out that no matter what kind of sunglasses, you’d better not wear them for too long, because it will aggravate the burden of the eye.
We should wear sunglasses when we are going out, in order to prevent from strong glare and uv. However, when coming indoors, you’d better take it off to relax your eyes.
No matter prescription or non-prescription, you’d better not wear glasses for long time. Although tints can reduce harmful glare, but there are not so much ultraviolet light indoors, and long time wearing can reduces the adjusting ability of your eyes.
