1 To check out a pair of sunglasses that covers your eyes and line of site entirely.
2 To look for suglasses that are dark enough they will help reduce sun reflection and glare, but not glasses that are so dark you have difficulty distinguishing traffic lights or signs.
3 You need a pair of sunglasses which can provide UVA and UVB protection. Most of sunglasses provide this protection have a label that designates them as UV safe.
