A 21 year-old woman from Dongguang, China, has lost her vision permanently in one eye after playing an online mobile game for long hours.
Xiao Wu, 21, who had been addicted to a popular online game titled King of Glory, had been playing the game for the entire day on 1 October before she suddenly discovered something wrong with her eye.
She was rushed to Dongguang Huaxia Eye Hospital the next day, where doctors diagnosed her as suffering from retinal artery occlusion, a painless loss of monocular vision which normally occurs only in elderly people. The effect is non-reversible and results in permanent loss of vision.
The 21 year-old had reportedly been obsessed with the game. She would wake up at 6AM and start gaming till after 4PM. She would then take a nap and then continue until 1 or 2AM.
The doctors who treated her at the hospital warned of excessive fatigue caused to eyes. Damage to eyes can occur from staring at a computer or smartphone screen for hours on end.
