Pick the Right Sunglasses: Your Eye Health Depends on It!!

Contrary to popular belief, the color of the shades you wear hardly have any effect on the UV radiation entering your eyes. Just because it is darker, does not necessarily mean that your eyes are better protected. Often, when you wear darker sunglasses, you pupil widens, leading to a higher amount of light entering the eyes. This, in turn, allows more UV radiation into your eyes. UV protection comes from wearing sunglasses which are equipped with anti-UV ray lenses. So it is advisable to be careful while purchasing the same.

Sunglasses protect the eyes from cataracts (clouding of lenses leading to blurriness), caused mostly by excessive exposure to UV radiation. Pterygium (tissue growth over lenses leading to astigmatism) and macular degeneration, stemming from retina damage (often leading to blindness) can also be prevented by the correct eyewear.

Ultraviolet radiation, though in small doses can help your vitamin D intake, exposure to excessive amounts can cause sunburns and even cancer. And, it is also very detrimental to optimal health. Excessive UV light intake can lead to cataracts and destroy your retina. It can even aid tissue growth over the cornea, thus leading to blindness. Sunglasses go a long way in this regard; especially those which block both UV-A and UV-B radiation.

Sunglasses with larger frames, and often wraparound styles, help protect your eyes from the harmful UV radiation of the sun to a higher degree than smaller lenses or close-fitting glasses.
