Sunglasses that are labeled with a UVA/UVB rating of 100% to provide the most UV protection. Do not mistake dark-tinted sunglasses as having more UV protection. The darkness of the lens does not indicate its ability to shield your eyes from UV rays. Many sunglasses with light-colored tints, such as green, amber, red, and gray offer the same UV protection as very dark lenses. Children should also wear sunglasses that indicate the UV protection level. Toy sunglasses may not have any UV protection, so be sure to look for the UV protection label. This is especially important when doing activities around or on water because much of the UV comes from light reflected off the water’s surface. Sunglasses are the most effective when worn with a wide-brimmed hat and sunscreen.
