The widespread and seemingly harmless habit of checking an email or chatting on social networks while lying in bed just before you go to sleep at night can actually harm vision and even trigger temporary blindness, a new study warns. The cases of two women, aged 22 and 40, who customarily checked their smartphones while in bed and ended up suffering severe loss of vision in one eye for up to 15 minutes at a time over several months have been described in Thursdays New England Journal of Medicine.
The mystery was solved by an eye specialist who figured the problem should involve some kind of exposure and not be connected with internal health problems. I simply asked them, What exactly were you doing when this happened? Dr. Gordon Plant of Moorfields Eye Hospital in London said, according to the Guardian.
It turned out that both women had been using their smartphones while lying in bed on their side with one eye covered with a pillow. Thus one eye had to adapt to the bright light of the phone screen while the other remained in darkness. The phone eye had to catch up with the pillow eye when the women decided to put the phones away. This led to the simple phenomenon very scientifically termed transient smartphone blindness.
The one-eyed smartphone blindness is not particularly serious and can be easily prevented, once a person starts to look at the phone with both eyes wide open. The authors of the study, however, hope that it will contribute to avoiding unnecessary anxiety and costly investigations.
