A 21-year-old woman from Dongguan, China, was recently diagnosed with with retinal artery obstruction in her right eye, after playing a popular smartphone game almost non-stop.
The woman, known only as Wu, apparently noticed that she couldn’t see anything with her right eye on October 1st, while playing her favorite mobile game, King of Glory. Thinking she was just tired, she went to bed, but when she woke up the next day, she was still blind in her right eye. Her parents took her to the hospital, where she was diagnosed with a serious condition known as retinal artery obstruction. This usually only occurs in older patients, but doctors said that Wu’s eyes were incredibly fatigued by the stressed of constantly staring into the small smartphone screen.
