When kids pack for summer camp, sunglasses may not always top the supply list. But I made them a priority for my 12-year-old son Carson, who just started rowing camp in Florida, because eyes are vulnerable to damaging ultraviolet rays, which are especially intense near reflective surfaces. Ultraviolet rays can damage the eyes several way, ultimately leading to cataract, glaucoma, macular degeneration, and other thieves of vision. You don’t have to spend a bundle to get a good pair of sunglasses. Just make sure to pick ones that block close to 100% of ultraviolet A and ultraviolet B (UVA and UVB) rays.
