Ultraviolet (UV) radiation from the sun can damage your eyes, not just your skin. Choose sunglasses that block 99 to 100 percent of both UVA and UVB rays. Skip sunglasses that are labeled "cosmetic" and those that don't offer details on the amount of UV protection. Opt for larger lenses rather than smaller lenses. Better yet, choose wraparound sunglasses. Be aware that while polarized lenses reduce glare, they don't offer any UV protection unless they're specifically treated with UV coating.
