When deciding on a pair of sunglasses, pay particular attention to the UV protection label. Avoid any pair that promises UV protection without offering specific numbers. Smaller frames may complement your face, but they allow UV light to sneak in at the sides. Gray lenses, your best bet for everyday use, provide the most authentic colors.
Brown tones enhance depth perception.
Amber lenses, while popular among skiers for their ability to define faraway objects, distort colors and should not be worn while driving. Try before you buy. Perform a couple of simple quality checks. First, slip the sunglasses on in front of a mirror. If you can see your eyes easily through the lenses, they probably aren't dark enough.
