You may think sunglasses are just a fashion accessory or something to wear in the summer, however they are a key component to eye health here in Colorado. Sunglasses protect your eyes, and the skin around them, from the sun’s harmful UV rays. At a mile above sea level the sun's harmful UV rays are magnified another 20% every day. Those of us who enjoy all the activities of Colorado's high country increase our UV exposure up to 50%. That's brutal on eyes without sun protection.
