Why UV Eye Protection in Sunglasses Matters

Why UV Eye Protection in Sunglasses Matters

UV radiation is damaging to both the skin and the eyes. It can damage your eyes in several ways, so it is important to wear sunglasses with UV protection when you are outdoors. This will protect both your eyes and the skin around your eyes. If you need new sunglasses to protect your eyes from UV rays, contact our eye doctors at Karns Vision Center in Knoxville for prescription and non-prescription sunglasses. Let’s look at why wearing sunglasses is more than just a fashion statement.

Harmful to the Eyes

Exposure to UV rays can cause damage to several different areas of the eyes. UV rays can damage the lens, the cornea, and more. When the UV rays damage the lens, it can cause cataracts to form or to get larger more quickly. UV rays can also cause growths to develop in the eyes. UV rays make it more likely that you will develop macular degeneration, which is a serious eye disease that can cause you to lose your central vision. To protect your vision, you need sunglasses that provide UV protection.

Sunglasses That Protect Your Eyes

It was once common for sunglasses to leave people vulnerable to UV rays, but today's sunglasses are usually made with UV protection. Most sunglasses today will have a sticker on them to confirm they block UV rays. You should look for lenses that block either 99% or 100% of UVB and UVA rays. The sunglasses should block about 75% to 90% of the light coming into them. Look at the lenses to make sure they both look exactly like each other and that there are no imperfections that could indicate a problem with UV protection. The lenses should not have any distortions.
