In Florida we all know how damaging UV radiation is for the skin based off of all the unintentional sunburns we’ve had But many of us don’t think about the damage it can do to your eyes. Thankfully the team over at The American Optometric Association have a wealth of information on why its important to protect your eyes just as much as your skin.The sun supports life on our planet, but its life-giving rays also pose dangers. The sun’s primary danger is in the form of ultraviolet (UV) radiation. Artificial sources can also produce UV radiation.Most people are aware of how harmful UV radiation is to the skin. However, many may not realize that UV radiation can harm the eyes, and other components of solar radiation can also affect vision.
There are three types of UV radiation. UV-C is absorbed by the ozone layer and does not present any threat. However, UV-A and UV-B radiation can have long- and short-term negative effects on the eyes and vision. If your eyes are exposed to excessive amounts of UV radiation over a short period of time, you will likely experience photokeratitis. Like a “sunburn of the eye,” photokeratitis can be extremely painful. Its symptoms include red eyes, a foreign body sensation or gritty feeling in the eyes, extreme sensitivity to light and excessive tearing. Fortunately, these symptoms are usually temporary and rarely cause permanent damage to the eyes.The longer the eyes are exposed to solar radiation, the greater the risk of developing cataracts or macular degeneration later in life.
