What to look for in a pair of sunglasses!

If you are not purchasing sunglasses from your optometrist, make sure what you plan to buy is at least labeled with a sticker that says "blocks 95-100% of UV rays," or "UV absorption up to 400nm." If the sticker on the sunglasses simply says "blocks UV rays," I would not recommend buying them, as it is highly unlikely that you will be getting the protection you need!
