Studies have proved that long-term exposure to UVA will lead to cataracts and damage to the retina. UVB rays do not have as much energy as UVA ones do, but if overexposure can give you skin cancer in the eye area. Being exposed to UVB rays for a shorter length of time will cause the corneas to become inflamed. This has the effect of short term blindness lasting over twenty four hours.
It is proven that 80 percent of your exposure to the sun happens before age 18. Children generally spend more time outdoors than adults this is why it is important to protect your child’s eyes as well as your own. Look for glasses that will block out at least 99 percent of both UVA and UVB rays.

The color of the lenses only matters for the protection from HEV rays. HEV stands for high-energy visible radiation. This will sometimes be called blue light.
{Ultraviolet light rays do have more energy than HEV rays, but HEV radiation will go deeper into the eyes and have damaging effects on your retinas. A reddish brown, bronze or copper lens is best for protection from these rays. The label on these glasses might say blue blocking. You can find glasses that will protect you from all of the harmful rays.Ultraviolet light is stronger than high-energy visible light, but the rays from the HEV light go deeper into the eye.
