Could using your phone at night cause blindness? Chinese man needed emergency op after spending hours texting his girlfriend in the dark
A Chinese man who texted his girlfriend for hours in the dark risked going blind after his retina detached from the back of his eye.
The 26-year-old suffered the condition retinal detachment after using the messaging app, WeChat, almost constantly over several days and nights.
Doctors who diagnosed the condition, which can lead to blindness, took the man into surgery for an emergency operation to fix the problem.
Without prompt treatment, the condition can lead to blindness in the affected eye.
The retina is light-sensitive and sends messages to the brain through the optic nerve.
The man had reported experiencing sudden flashes in his line of sight, a common sign that a retina has become detached.
The condition occurs when the thin lining at the back of a person's eye - the retina - begins to pull away from the blood vessels that supply it with oxygen and nutrients.
The condition usually strikes between the ages of 50 and 70 - but scientists say an increasing number of young people are suffering from it - and smartphones could be to blame.
Medical Daily reported the Chinese man had been texting his girlfriend constantly throughout the day and for several hours in bed at night.
Yu Bin, an eye expert, told Want China Times this was an extreme case, but added it was possible for people to experience a retinal detachment as a result of excessive phone use.
Experts say starring at devices, such as phones and tablet computers, can put unnecessary strain on a person's eyes.
'Our eyes have evolved for three-dimensional viewing,' Andrea Thau, a New York City-based optometrist, told NBC News.
'So we wind up overfocusing as we strain to find a 3-D image on a close-up 2-D screen.'
Last year an eye surgeon warned that rates of short sightedness among young people have soared because of smartphones.
David Allamby, Founder of Focus Clinics, said there had been a 35 per cent increase in the number of people with advancing myopia (short sightedness) since the launch of smartphones in 1997. He added that the problem could increase by 50 per cent in the next ten years.
