Tourists who buy cheap sunglasses from beach sellers overseas could be risking blindness and eye cancer.
A total of 35 per cent of the rip-offs of famous brands offered zero protection against UV rays, a study found, which meant wearing them in bright sunlight could cause irreversible damage, The Sun reported.
A survey found 18 per cent of those buying sunglasses did not check for UV protection, and 11 per cent would still buy them even after finding they offered no protection.
An added problem for drivers was that many of those who would normally wear prescription glasses wear non-prescription sunglasses in bright sunshine.
“If people cannot see to drive safely, either through not wearing the correct prescription lenses or sunglasses to protect from glare, they pose a real danger to themselves and everyone else on our roads.”
