Even if you can’t see the damage done, your eyes can get sunburned, which may lead to serious health issues and, in rare cases, ocular melanoma. “Sunglasses are critical since bikers and runners have an increased risk of cataracts,” says Jackson. “They can also protect the ‘crow’s feet’ area.” She suggests polarized glasses, like Oakley’s Polarized Fast Jacket ($280, Oakley.com) or Smith’s Pivlock V90 Max ($139, Smithoptics.com). “Make sure they’re 96–97 percent filtered,” says Jackson. And for all of those summertime swims in outdoor pools, you can purchase goggles that offer 100 percent UV protection like the Speedo Vanquisher 2.0 ($17.99, Speedousa.com).
