Cheap sunglasses may damage vision: Experts

Vijayawada: Wearing poor quality sunglasses in summer may create serious eye problems. Ophthalmologists warn not to use poor quality UV Sunglasses which may harm and create long term vision defects. Usage of sunglasses have increased in recent time with high UV index mostly UVA and UVB rays and increase in temperatures. Motorists as well as pedestrians are wearing shades to protect their eyes from scorching summer heat.

But a majority of the motorists prefer cheap shades sold by hawkers at a cheaper price which does not have polarization, UVA and UVB filters. “We use sunglasses in summer to get reading the scorching sunlight. It is just a matter of two three months and so we are buying cost effective shades from street vendors. These shades were dark enough to ban sunlight and give clear vision” says D.S.N Murthy, a commuter.


Wearing cheap glasses may increase the risk for cataract, macular degeneration and other eye problems, says ophthalmologists. “Wearing full dark sunglasses will increase pressure on eyes and as a result pupil opens up by half mm to 5mm to catch the proper vision and which also allows dangerous UVA and UVB light rays into eyes which may damage them ,” says Dr Siva Kumar Wurity, Cornea expert and faculty at L.V Prasad Eye Institute.

There are some other long-term effects like Pinguecula, a yellow fatty deposit on white part of the eye and short-time damage but not in all cases, he said. It is better not to wear shades instead of wearing cheap glasses, Dr Siva Kumar added.
