What type of sunglasses should I get?
When you buy your sunglasses, look for a label that tells you how much UV radiation the lenses of the sunglasses reflect. Experts say that your sunglasses should block 99-100% of both UV-A and UV-B rays. You should also consider wearing a wide-brimmed hat along with your sunglasses.
