Omni Eye Care Center of Plano, Texas has published a guide to eye care for those bright summer days and describes some of the harmful effects that sunlight can have on unprotected eyes. Public awareness of skin damage is high, and most people are ready with sunscreen, parasols and at least some covering clothing when it’s time for the beach or a day in the park. But the dangers of extreme exposure to bright sunlight on the eyes is something many aren’t aware of and, as such, do not take the proper precautions against. The damaging effects of ultraviolet radiation on our eyes can be just as severe as it is on the skin. Even short-term exposure to extremely bright sunlight will cause a type of sunburn on the eyes. A condition called “photokeratitis,” which is referred to as "snow blindness," is actually a type of sunburn which affects the cornea and conjunctiva. The conjunctiva is a membranous lining which covers the inside of the eyelids and the outside of the eyeball. This sensitive membrane can, like the skin when sunburned, experience inflammation, pain and redness that can last up to 48 hours before symptoms begin to abate.
