Just because your sunglasses are deeply tinted doesn't mean they're doing you any good. In fact, they could be making things worse for your peepers. According to SELF, when you're wearing dark sunglasses, instead of constricting (like they normally do in sunlight), your eyes end up dilating. This lets in MORE UV light.
What does UV light do to your eyes?
So think twice about buying your sunglasses at the nearest tiangge. Invest in a pair that has 100 percent UVA/UVB protection. Legit sunglasses will always have a UV sticker or tag. Just to be sure, look for a line that guarantees blockage of 75 to 90 percent of visible light.
