A Chinese man had to have his contact lenses surgically removed after he did not take them out for a year.
Liu, 40, started to wear contact lenses a year ago and never took them out because he found it difficult.
"I only have some eye drops for when they feel uncomfortable," he told Chutian City News.
Liu recently felt his eyesight was getting worse, so he bought another pair of lenses and wore them on top of the old ones.
But when his eyesight still didn't improve, he took another startling decision.
"I put a pair of used disposal contact lenses over the other two pairs in my eyes. By then, I was wearing three pairs of lenses," he said.
By the next day, Liu's eyes had reacted badly to his DIY eyecare and he finally sought medical attention.
A doctor was shocked to find the first lenses had grown into his eyes and surgery was needed to take them out.
