(Shanghai Daily) Doctors have said that spending hours peering at a smartphone in the dark every day led to a woman in east China’s Zhejiang Province suffering a detached retina.

The woman, surnamed Liu, had noticed that the vision in her right eye had been cloudy and distorted over past last week.

Liu said she spends two to three hours on average looking at her phone in a darkened room.

“When the doctor covered my left eye, everything I saw with my right was distorted. Rectangular objects become elliptical,” she said.

The doctor who treated Liu said she had suffered a partial retina detachment and blamed this on using a smartphone in the dark.
