Most people who purchase sunglasses only look at the brand name, perice and style and not the primary function of sunglasses which is the protection of your eyes.

Overexposure to UV [ultraviolet] rays has been linked to a variety of problems, including age-related cataracts and degeneration of the cornea. Other disorders that can occur are abnormal growths on the eye’s surface and even sunburn of the eyes. These conditions can cause blurred vision, irritation, redness, tearing, temporary vision loss and, in some instances, total blindness.

People should wear good quality sunglasses that offer proper UV protection and a wide-brimmed hat whenever they’re outside. Some contact lenses also contain a UV blocker that helps protect the eyes.

The following should be observed:

  1. Wear UV-protective eyewear even on cloudy days and in the winter.
  2. Select quality sunglasses or contact lenses that block out 99 to 100 percent of UV-A and UV-B radiation and screen out 75 to 90 percent of visible light.
  3. Make sure that sunglass lenses are perfectly matched in color and free of distortions or imperfections.
  4. Select gray-colored lenses because they reduce light intensity without altering the color of objects, which means they provide the most natural color vision.
  5. Get regular eye exams to monitor eye health, maintain good vision and keep up-to-date on the latest in UV protection.
  6. It’s also especially important for young children and teens to have UV-protective eyewear because they typically spend more time in the sun than adults, putting them at greater risk for eye damage.
