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
e
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
