You find yourself in the habit of checking your smartphone immediately after waking up or before you go to sleep? Then you might be interested to know that it can cause your eyes quite considerable damage.
More recently, in the UK two interesting cases of transient blindness were reported. Women complained of similar symptoms, one experienced a short-term vision problems immediately after waking up, and the second - before going to bed. Doctors have linked this phenomenon with the use of mobile phones: it turns out, lying in bed on your side with your smartphone before the eyes may cause temporary vision problems.
In the journal The New England Journal of Medicine was published detailed information on these two cases.
The first patient was a 22-year-old girl. She complained that at night no longer see his right eye. During the year it was repeated several times a week, but vision returns quickly. Finally, she still decided to see a doctor, who, after examination, checking blood vessels and several tests found no abnormalities. It has even conducted a survey designed to identify whether there is a girl of any heart problems. However, all in line with the norm: the patient was perfectly healthy, but the eye occasionally seen.
The second victim was the temporary blindness syndrome 40-year-old woman who described her doctor similar symptoms for six months, she lost the ability to see with one eye immediately after awakening. After 15 minutes, the vision was restored. The situation repeated itself again: no abnormalities and disease was not observed, examinations have revealed nothing.
Doctors began to find out what factors could be due to this temporary loss of vision. After further questioning patients following pattern was found: advancing blindness after a woman for some time staring at the screens of their smartphones. At the same time they often did it lying on its side, because of what one eye was partially covered with a pillow.
Doctors have concluded that these two phenomena are related. Eyes covered with a blanket or a pillow, adapted to the darkness, and the public eye, on the contrary, he has adjusted to the bright light coming from the screen of the smartphone. When the display is extinguished, accustomed to the bright glow of the eyes ceased to see, as long as again not to get used to the light.
Doctors are not limited to patients with questions, they decided to test the theory on himself. Of course, with smartphones, they have not acquired a temporary blindness syndrome after a brief experiment, but still noted some deterioration in the ability to see with one eye.
The study's authors believe that further visits to doctors with similar complaints will be more and more. Brightness display phones and other gadgets is increasing, and people are more and more depends from them.
Scientists studying temporary blindnessWe describe these two cases in order to help others save time doctors in the diagnosis and avoid unnecessary worry and costly research.
If you suddenly notice at similar symptoms, try to get rid of the habit of looking at the screen with one eye. Does not work? Then, at least a little, turn down the brightness of the display. After all, it is not clear how it affects our retina.
