UV and its Effects on the Eyes

The depletion of the ozone layer has become a serious problem for the health and welfare of the world's population. As the ozone layer depletes, we are becoming more and more exposed to harmful ultraviolet radiation. UV effects all parts of our bodies, including our eyes. UV has been proven to cause various eye problems, such as cataracts, sunburn to the eyelids, pterygium, skin cancer around the eyes, and macular degeneration, one of the leading causes of vision loss among older Americans.

Ultraviolet is the invisible part of light, made up of UVA, UVB, and UVC rays. With prolonged exposure to UV, you eye may begin to turn opaque. Ultraviolet light is found between 50 nanometres and 380 nanometres (wavelength of light), whereas visible light is between 381 nanometers and 770 nanometers. The term UV 400 stems from this. It is recommended that you protect yourself from UV radiation up to 400 nanometers, which extends into part of the visible spectrum to ensure complete blockage of ultraviolet light. This is what distinguishes "cheap" sunglasses from more expensive ones. Dime store sunglasses often say that they protect from UV when they really do not. Most will block harmful UVC and UVB rays, but most do not block the most damaging UVA rays. This is why UV 400 is so important. UVA rays are the ones closest to the visible spectrum, and are known to cause cataracts and pterygium at 300 to 380 nanometers. Since most inexpensive sunglasses to do not cover this range, you are still at risk. Thus, it is worth it to spend a little more to guarantee full protection.

Other Factors Affecting UV:

Many other factors affect the amount of UV that will actually reach your eyes. As already mentioned, the depleting ozone layer is continuing to increase our risk every year. Reflections off the earth's surface also compounds the effects. Earth and grass reflect 5%, sand 17%, water 20%, and snow 85%. This is why it is so important to wear eyewear with UV protection when participating in outdoor sports. Clouds and haze may also increase the amount of radiation reaching the ground, where dark clouds may actually reduce the amount of radiation. The seasons and the time of day also make a difference. Contrary to what you might first assume, UV radiation is most in the winter and spring, than it is in the heat of the summer. In fact, it is almost 17 times as bad in the winter and spring, than summer months. Also, at noon, the amount of radiation is ten times more than during other hours. Altitude also increases radiation, with an increase intensity of 16% for every 1000 meters above sea level. This compounded with the reflection of snow, and the winter and spring months make the biggest risk for UV radiation damage. Thus, those participating in winter sports should take the necessary precautions. Pharmaceutical drugs may also increase you susceptibility to UV radiation. Check with your doctor if you are on any medications.
