Infrared rays are heat rays. If you are exposed to intense sunlight (a day at the beach for example) without infrared protection you may experience a stinging or burning sensation in your eyes. There are ways to protect your eyes from the UV rays. Make sure you wear eye protection with sunglasses. Also when working outside you may find it beneficial to wear a wide brimmed hat that will block the UV rays from above and around the glasses. When choosing sunglasses, consider when and where they will be used. Too dark of lenses can cause visibility problems when driving from bright to shady areas. Wearing dark lenses, the eyes can become “addicted” to the dark lenses and wearers find that they can’t tolerate even moderate glares. For outside activities, sunglasses should block at least 95% of ultra violet light. Polarized sunglasses filter the glare that reflects from horizontal surfaces making eyes more comfortable when driving or doing sport activities.

When purchasing sunglasses for children, make sure they fit well and consider impact resistant lenses to prevent injuries.

Ultra Violet light
is defined as electromagnetic radiation. With the prolonged or immediate
(as in welding) exposure to ultra violet rays it can lead to macular
degeneration, certain kinds of cataracts, growths on the cornea, or skin
cancer around the eyelids. Ultra Violet –A rays damages the macula which
is part of the retina. The Ultra Violet –B rays can damage the front part
of the eye which consists of the cornea and the lens, absorbing most
of the UV-B rays and can cause the most damage to your eyes.
