Glares that care

If you thought that the harsh sun only affected your exposed skin, think again! It is not just your skin but also your eyes which suffer because of the sun’s harmful UVA and UVB rays. The fancy stylish sun-glasses we use are absolutely of no use in protecting eyes. Too much exposure to sunlight increases the risks of eye diseases like cataract, growths on the eye, and cancer. Some of these diseases take many years to develop, but when they do surface, they often leave devastating effects on our eyesight.

The most common and obvious way of protecting your eyes from the sun are glasses. But these days’ glares are more about fashion and less about care. When we buy glares, we opt for the trendiest options, but without checking its UV protection factors.

Understand that UV radiation in sunlight - UVA and UVB - can cause harmful damage to human body in more than one way. According to researchers, UVA rays have deeper penetrating effect on your eyes. These rays may injure the macula, the part of the retina responsible for sight. On the other hand, exposure to UVB rays results in external growth or discoloration of the eye.  Cataracts are in fact opacity formed in the natural lens of the eye often caused by long term exposure to UV radiation. Chronic UV exposure may contribute to the aging processes in the retina, leading to macular degeneration and poor vision.

Pterygium is a fleshy growth on the white part of the eye that may extend onto the clear cornea where it can block vision. It presents most commonly in people who work outdoors in the sun and wind, and is correlated to the amount of UV exposure. And Photokeratitis is reversible sunburn of the cornea resulting from excessive UV-B exposure. It occurs from spending long hours on the beach without UV sun protection. It can be extremely painful for 1-2 days and can result in temporary loss of vision.

To avoid the above it is essential to follow some dos

• Do use Ultraviolet protecting sunglasses. Buy a wraparound design in glares so that your eyes are well protected
  

• Use wide brimmed hat when on excursions in the outdoors

• Buy sunglasses only if there is a UV label. Labels should be examined carefully to ensure that the lenses purchased absorb at least 99 per cent of UVA and UVB light 

e

• Wear waterproof eye make-up as sweat may cause it to enter inside the eyes 

Don’ts

• It is not necessary that glares of darker tint provide more UV protection. Also, don't be misguided by the price -- higher priced sunglasses usually reflect fashion or durability, not UV protection   

• Don’t rub your eyes with unclean hands or when you are outdoors and in public places   

• Don’t splash water inside your eyes, as is a habit for some people. This washes away the tear film that is a protective layer and can cause dry eyes
