You cannot tell how much UV protection a pair of sunglasses will provide by their price, color, or by the darkness of the lenses. Before you buy a pair of sunglasses, make sure they offer UV 400 protection, which refers to protection from 400 nanometers UVA and UVB. The sunglasses should have a label on the sunglasses that says either "UV 400" or "100% UV Protection."
You don't necessarily need to spend a lot of money on sunglasses to get full protection from UV rays, you just need to make sure the sunglasses have the protection before you buy them. Many people think that a really dark lens means the protection from UV rays is the best, but this is a myth. Always look for labels.
