Two women aged 22 and 40 have become subjects of a new study after they suffered temporary vision loss from looking at their smartphones in bed.
The strange medical medical phenomenon was discovered after standard tests were found inconclusive. According to doctors the problem isn’t caused by being in bed.
Instead it was caused after both women checked their phones with one eye on the screen and the other covered by a pillow. Where the phone eye adapts to the light by being less dilated, the pillow eye is more dilated and adapts to the dark.
After the phone is switched off, the phone eye takes a while to adjust to the dark and catch up to the pillow eye, causing the feeling of temporary blindness. There wasn’t any true vision loss, but it was an effect similar to how we feel “blind” right when we go into a dark room after being outside.
