Improving My Eyesight

Today’s recommendations are about protecting your eyes from the harmful rays of the sun.

Sunglasses should be a part of your daily attire. Here’s what to look for in a good pair of sunglasses:

Expensive does not always mean protective.

What really counts is the degree to which the lenses filter out UV rays. Make sure your sunglasses have a statement on the label telling you how much UV protection they offer. The American Optometric Association offers a Seal of Acceptance for sunglasses that block 99% to 100% of UV radiation. Look for this seal to be sure you are getting the maximum protection.

Darker is not always better.

Although it would seem that the darker the sunglasses, the more light they block, in fact dark sunglasses may still allow UV rays to enter the eye. They can even be more harmful than wearing no glasses at all, because they cause the pupil of the eye to dilate, which allows more UV rays to enter. It’s a special coating on the lens that makes them safe, not their darkness.

Choose the special feature that’s right for you.

Polarizing lenses, which reflect glare from snow, water, and roads, are good for skiers, boaters, and cyclists. Photochromic lenses darken or lighten with the amount of light present and may be useful if weather conditions are erratic. Mirror coatings are best for intense glare (snow or water). Wraparound and close-fitting frames block more glare, wind, and debris around the sides of the eyes.
