Snowblind—it’s a frightening word. Thankfully, it’s a condition that is totally preventable.

Snow blindness is a painful, temporary loss of vision due to overexposure to the sun’s UV rays. Essentially, snow blindness is caused by a sunburned eye.

1. Though it is commonly called snow blindness, the condition can (and often does) occur in the absence of snow.

The terms “snowblind” and “snow blindness” have become popular because snow is highly reflective of ultraviolet radiation. 2. Also, skiing, mountain climbing and snowboarding usually take place at relatively high altitudes, where the sun’s UV rays are stronger. Combined, these factors can double your risk of getting sunburned eyes, compared with being outdoors at lower altitudes in the summertime.

3. Television journalist Anderson Cooper experienced snow-free snow blindness first-hand a few years ago when he spent a couple hours on a boat in Portugal without sunglasses and ended up “blind for 36 hours,” according to his report of the incident.

Not only can you become snowblind without snow—it can happen without sunlight, too! 4. For example, sun lamps can cause temporary “snow” blindness if proper eye protection is not used.

5. To relieve pain or discomfort from snow blindness, stay indoors and wear sunglasses. Keep your eyes well-moistened with artificial tears. For additional relief, use over-the-counter pain relievers. Be sure to use only pain relievers you know you can take without worry of an allergic reaction. You also may find that placing a cool, dampened washcloth over your closed eyelids is comforting.

A. You don’t need snow to become snowblind.

B. It will likely affect those traveling in snowy conditions.

C. To prevent snow blindness on the slopes, wear sunglasses.

D. Sometimes it occurs from mail-made sources of ultraviolet radiation

E. In fact, snow can reflect over 80 percent of the UV rays that fall upon it.

F. Snow blindness is scary, but usually it’s temporary, and there are ways to relieve the discomfort.

G. But water and white sand also are highly reflective of the sun’s UV rays, thus increasing the risk.
