Smartphones Can Cause Temporary Blindness

Two British women recently suffered from temporary blindness. Their doctors diagnosed it as “temporary smartphone blindness.” They discovered that it was caused by lying in bed while looking at a smartphone, and they are warning against it, as a long-term habit of doing this can cause retinopathy.

Apple Daily, a newspaper in Taiwan, reported on the article published by British ophthalmologist Dr. Gordon Plant in the latest issue of the New England Journal of Medicine. The article states that two women in the UK, aged 22 and 40, had suffered multiple episodes of “temporary smartphone blindness,” each lasting for a duration of 15 – 20 minutes, in the previous months.

Each of the women had visited the emergency room several times. They had each undergone extensive testing, including blood tests, MRI’s, and a cardiac examination, with no obvious cause for the blindness found. They were eventually referred to the Moorfields Eye Hospital, where they were treated by Dr. Plant. He found that the patients had no underlying health issues, but they shared a bad habit of lying down in bed while playing with their phones.

Temporary blindness can result from your eyes having difficulty adjusting to different speeds of light. These symptoms have been known to occur in people who watch TV while lying down.

Human pupils become enlarged in a dark environment to allow more light to enter the eye. If your eyes are exposed to too much light in a dark environment (i.e., looking at a phone screen in the dark), this can lead to retinopathy.

Temporary blindness is not only caused by lying down. Viewing a mobile phone for a long time at close range may also cause retinopathy, and this may also lead to glaucoma.

Expert advice:

  • It’s best not to use your mobile phone while lying down.
  • Turn on the light if you must use the phone while you’re in bed.
  • Take a break of a minimum of 15 to 30 seconds for every 15 minutes of phone use, and change your posture.
  • Activating the night mode on your phone can help to alleviate eye fatigue.
  • Keep your eyes looking straight ahead.
  • Keep your phone at least 30 cm away from your face.
  • A hot towel can also help to ease eye fatigue.
