Most of us are familiar with the damage the sun can do to our skin, but we may not think about what ultraviolet rays can do to our eyes.

The sun gives off two types of ultraviolet rays: UVA and UVB.

UVA radiation can penetrate deep into the eye and damage the cornea or retina and UVB rays can cause corneal sunburn, which is painful and may cause temporary vision loss.

"The cornea is one of those exposed mucus membranes. It's a very moist organ and it needs to be continually lubricated,” said Dr. Rishi Singh of the Cleveland Clinic. “So, having it exposed to sun elements and dry it out completely only leads to a significant decrease in vision."

Doctors say sunglasses offering both UVA and UVB protection are your best defense for protecting your eyes.
