Product Features



EFFECT OF UV RAYS ON OUR EYES


There are two types of UV rays we should be most worried about—— UVA and UVB.


UVA rays pass through the cornea to reach the lens and retina inside your eyes. Overexposure to UVA radiation has been linked to the development of macular degeneration-damage to the retina that causes loss of central vision, and certain types of cataracts- a clouding of the lens that leads to a decrease in vision.

UVB rays are partially filtered by the ozone layer, but are more intense than UVA rays. They penetrate less deeply and are completely absorbed by the cornea. In short term doses, UVB rays have been known to cause " snow blindness", a painful inflammation of the cornea that cause temporary vision loss.


The best way to protect your eyes is wearing good quality UV protection eyeglasses whenever you are outside.
