Picking Sunglasses for Protection:

1.Aim to protect your eyes first and foremost. Excessive exposure to UV radiationcan cause a variety of problems for your eyes such as cataracts, burns, and cancer.

2.If you want your sunglasses to protect you from these risks, look for pairs that block at least 99% of UVB rays and at least 95% of UVA rays. Also look for the amount of cover the sunglasses provide. Look at how much you can see around the frames––will the sunglasses let in sun from the top or sides?

· Are you getting these sunglasses for sports or spending significant time outdoors? Choose ones with a nice close fit, possibly with rubber grips on the arms. If they are for fishing or use on water, polarization is a must; polarized glasses provide more sun protection.

3.Don't buy sunglasses if they're labeled as "cosmetic" or don't provide any information on UV protection. Look for scratch resistance, many lenses have very fragile coatings. If you are spending much money, you want them to last. Fortunately damaged lenses can be replaced for most models.How to Fix Scratches on Oakley Sunglasses.
