Check your Sunglasses for UV Safety.
What is UV? UV stands for “ultraviolet” and ultraviolet light is the kind of sunlight rays which reach our earth. There are two kinds of ultraviolet light which come into our planet’s atmosphere: UV-A rays and UV-B rays. These rays are not blocked by the ozone around our planet.
UV-A light can cause the skin to age and wrinkle. UV-B is the kind of light which can cause sunburn. Both UV-A and UV-B light can cause skin cancer.
UV radiation is highest on sunny days at noon. UV radiation can be strong during daylight in areas of snow and sand as well.
Obviously, people who are outdoors on sunny days are most at risk for sunburn. Those who have been sunburned recently are also more at risk for sunburn again. UV radiation is also damaging to your eyes.
How can you protect your eyes from UV rays?
- Wear sunglasses when you go outdoors.
- Check your sunglasses for 100 percent UV safety protection. Read the tag or label. Make sure your sunglasses block 100 percent of UV-A rays and UV-B rays. The darkness of the lens does not indicate the effectiveness of the sunglasses. Scratch-resistant lens may be useful for you. Even inexpensive sunglasses can provide 100 percent UV protection.
- Choose wrap-around styles for best UV safety. Ideally, your sunglasses should wrap all the way around to your temples, so the sun’s rays can’t enter from the side. It is possible to get sunglasses which fit around your eyeglasses or which clip on the lenses of your eyeglasses.
- In addition to your sunglasses, wear a broad-brimmed hat to protect your eyes.
- Protect your eyes during peak sun times. It is particularly important to wear sunglasses in the early afternoon and at higher altitudes, where UV light is stronger. Wear polarized sunglasses when driving on bright sunny days whether you are a driver or a passenger because polarized sunglasses can deflect glare.
