According to Local 10 News, a Chinese woman was temporarily blind after blood vessels burst in her eye due to using her IPhone all night long. She went to sleep and when she woke up the next morning she went at it again. “About five minutes later, she wasn't able to see out her left eye. She couldn’t see anything,” said Dr. Qiu Wangjian. According to his diagnosis the ruptures were caused by, "the physical exertion of prolonged periods of staring."
