Ultraviolet keratitis, or snow blindness, is the exposure of insufficiently protected eyes to UV light. It is basically the outer layer of the cornea protecting the rest of your eye being eaten away. Obviously this is an extreme example, but over the course of a lifetime of exposure protecting your eyes will help. Like was stated above, 5$ glasses are doing you nothing.
100$ a pair plus or minus about 40$ is my price range for sunglasses. I'd rather have 2 or 3 quality pair than 15 shitty pairs.
