The American Optometric Association estimates that 47 percent of consumers do not check whether sunglasses offer adequate UV ray protection before purchasing them.
Not protecting your eyes from UV rays can result in cataracts and cancer of the eyelids later in life. Keep these tips in mind when purchasing a pair of sunglasses:
· The sunglasses should block 99 to 100 percent of UV radiation.
· A uniform tint should be present. A grey tint is best for color identification while driving.
· The sunglasses should screen out 75 to 99 percent of visible light.
· The frame of the sunglasses should stay close to your eyes and curve around your face to offer protection from multiple angles.
