A 26-year-old man in Qingdao in eastern China's Shandong province has experienced a retina detachment after using his smartphone for too many hours in the day, reports the local Chinese-language Qingdao Daily.
The man had been using messaging app WeChat non-stop during work and even in bed, chatting with his girlfriend on the app in the dark.
He recently complained that he saw flashes but by the time he went to the doctor about it, the retina in his left eye had become detached, necessitating surgery to restore his eyesight.
Eye expert Yu Bin said that although this is an extreme case, people using smartphones for extended periods of time often experience dry eyes or contract conjunctivitis and keratitis. Retinal detachment is more common among older people but the average age of patients has been getting lower, Yu noted.
