Sunglasses are a great fashion accessory, but their most important job is to protect your eyes from the sun’s ultraviolet (UV) rays.
Some of the sun’s effects on the eyes include:
- Cataracts, a clouding of the eye’s lens that can blur vision. An estimated 20% of cases are caused by extended UV exposure over a life time.
- Macular degeneration, resulting from damage to the retina that destroys central vision. Macular degeneration is the leading cause of blindness in the United States.
- Pterygium, a tissue growth over the white part of the surface of the eye that can alter the curve of the eyeball, causing astigmatism.
- Keratitis is an inflammation of the cornea (like a sun burn on the surface of the eye).
When purchasing sunglasses, look for ones that block out 99 to 100% of both UVA and UVB radiation, so you can keep your vision sharp and eyes healthy. A wide-brimmed hat offers great protection, too! And even better, couple the hat with sunglasses. That offers the most protection of all.
