A woman in China has gone blind in one eye after playing a game on her phone for an entire day, according to local media.
The 21-year-old reportedly played Honour of Kings without stopping, but in the evening she found she could not see out of her right eye.
Her parents then took her to several hospitals, but doctors were unable to work out why she had gone blind, according to The South China Morning Post.
Eventually on Wednesday (October 4) the woman was diagnosed with a retinal artery occlusion at a hospital in the Nanchang district.
A doctor said cases of this condition are usually only seen in elderly people but it was probably caused by severe eye strain.
The woman told local reporters that she had become obsessed with the game, playing it after work and at the weekend.
She agreed that the game had probably caused her eye condition and said: “Sometimes I would be so absorbed in the game that I would forget to eat, and not listen to my parents when they told me it’s time for dinner.”
Reports claim she is still being treated in hospital as doctors hope they may be able to improve her eyesight.
The game she played is a historical battle game and some newspapers have slammed it as "poison" due to it being addictive.
Due to this apparent addictiveness, the game now has restrictions on it. Those aged between 12 and 18 are only entitled to play it for two hours a day at most. Those under 12 can only play it for one hour a day and this must be before 9pm.
