In St. Louis, the doctors at Galanis Cataract and Laser Eye Center have two primary concerns, which are, the well-being and care of our patients. Most people know about the damaging effects of Ultraviolet (UV) radiation on the skin, but many are uninformed about the destructive abilities UV rays can have on the eyes. This blog is to inform our patients, because we know that knowledge and awareness is a part of prevention, and prevention is a part of staying healthy.

The Sources of UV radiation

Ultraviolet light, and its emitting radiation, does not just come from the sun. But artificial sources include; Tanning equipment, Certain Lasers, and other tools that discharge light like welding machines. There are three types of Ultraviolet Radiation, UV-A, UV-B, and UV-C, and it is UV-A, and UV-B that has the most damaging effects on the eyes.

Eye Diseases Caused UV Rays

There are specific diseases caused by long and short term exposure to Ultraviolet Light. These are problems that affect both the young and the old, and have nothing to do with heredity, but all to do with exposure to UV Rays.

Skin Cancer

UV rays cause skin Cancer around the eyes and eyelids.


This is a disease that is common among beach goers and other outdoorsmen who are in direct contact with the sun and wear no eye protection. Another name for Photokeratitis is snow blindness. This disease can be painful and even cause temporary blindness.


Although aging is a primary cause of cataracts, studies have now shown that UV exposure also causes this disease, which results in a cloudy matter invading the eyes.

Macular Degeneration

Age and UV radiation are key causes of this disease that damages the retina of the eyes, and can lead to blindness.


Though there is still much to learn about the cause of this disease, but it is believed to be sourced in UV exposure. It is not pink eye, but when one is plagued with this sickness a pink matter forms on the white of you eyes.

Protection and Prevention

Eye wear, hats, and other protective articles are your best line of defense if you have to be in direct contact with the sun for extended periods of time. Also, if you are a traveler, be aware that certain regions like Mountains and locations in the Sunbelt are areas that are UV magnets.
