Sure, there’s a cool factor at play here. But when you slip on your favorite pair of shades before you go outside -- every time you go outside -- there’s more going on than just a nice look. It matters for a lot of reasons. First, you'll ward off those little wrinkles at the corners of your eyes. They come from too much time in the sun. You'll protect the whites of your eyes from damage and block that eyeball-searing ultraviolet (UV) light. So grab those shades before you head for the beach, or the park, or anywhere outside -- whether it’s bright or cloudy. And buy some for the kids in your life, too. Follow these rules to pick a pair that look good and protect your peepers.
