Using smartphones in the dark may cause temporary blindness

Scientists have warned that the use of smartphones in the dark can cause temporary blindness.

According to the New England Journal of Medicine, doctors recently presented details of the case of two women (20 and 40 years old) who had temporary blindness due to using smartphones.

The two women complained to the doctor about a temporary loss of vision for about 15 minutes. They underwent many medical tests with MRI magnetic resonance scans and cardiac screening. However, doctors do not find any other problems in their health.

But just a few minutes after entering the office of an eye specialist, the mystery was answered.

Dr Gordon Plant of Moorfield Eye Hospital in London said: " I simply asked them what they did when this happened."

He explained that both women used their smartphones in the evening with one eye, their eyes were covered by a pillow. So you have an eye adapted to the light because it looks at the phone and the other eye is adjusting to the dark.

When they put down their phones, they can't see with their eyes and look at the phone. It is because this eye needs time to catch up with the other eye in adjusting to the dark, it is called this phenomenon " temporary blindness".

He said temporary blindness is not dangerous, easily avoided if we look at smartphones with both eyes.

One of the two women has temporarily reduced temporary blindness after a short time. The second woman remained skeptical of what Gordon Plant said and it took months to follow her, reassuring that she had no serious problems with her eyes. However, she said she could not stop the habit of checking the phone in bed every night.
