Spring is here, which means flowers, showers and occasional sunny days. Even when it’s not sunny out, it is still important to protect your eyes from the sun’s ultraviolet radiation. Over time, UV rays from the sun can potentially cause skin cancer and affect your overall health. Wearing sunglasses when the sun is out can help protect your vision for the future.
When a person’s eyes are exposed to long-term UV radiation, they are at greater risk for developing early onset cataracts, macular degeneration and other ocular conditions.
There are three categories of high-energy, invisible UV rays that are important to protect your eyes against, including:
- UVC rays. These rays produce the highest amount of energy and could potentially be the most harmful to your skin and eyes. The good news is that the atmosphere’s ozone layer blocks most of these rays.
- UVB rays. Although these rays have lower energy than UVC rays, their wavelengths are longer which allow some of them to reach the earth’s surface. In high doses, UVB rays can cause sunburn, wrinkles and skin discolorations which then increases the risk of skin cancer.
- UVA rays. These have the lowest energy, but they can pass through the cornea of an eye and reach to the lens and retina. It has been shown that overexposure of UVA radiation can lead to cataracts.
Wear Sunglasses That Offer UV Protection
Although any kind of sunglasses are great for protecting your eyes from the sun, there are certain kinds that are recommended to offer the best possible protection. When shopping for sunglasses, make sure to buy a pair that provides both UVA and UVB protection.
At Raleigh Eye Center, our Raleigh eye doctors can also schedule an eye exam to help determine the level of UV protection that your sunglasses need when you are outside on a sunny day.
