Sunglasses do more than hide you from paparazzi and make you look cooler than an Alaskan iceberg, they also provide valuable protection from the sun's harmful UV rays. Here are four ways to make sure you're getting everything out of your pair.

Get Complete Protection
Find glasses that filter out UV-A and UV-B rays (they don't have to be expensive). Look for a label that specifically states they offer 99 or 100 percent UV protection. An eye-care pro can test them if you're unsure.

Made in the Shade
Sunglasses should be dark enough to reduce glare, but not dark enough to distort colors (which could affect the recognition of traffic signals). Tint is a matter of personal preference.

Double Protection
People with contacts made with UV protection should still wear sunglasses. 

Hide Under a Hat
Since UV rays can still enter from the sides and top of sunglasses, it's smart to wear a hat with a three-inch brim to help block light.

Now what about those ears of yours?
