Why Using Your Phone In Bed Can Cause Temporary Blindness, Even After You Get Up
You've probably done this: Roll over in the middle of the night, or in a dark room, turn on your phone, read a few emails, scroll through some tweets, or check Facebook. Then later, your vision is fuzzy in one eye, or worse, you roll over and can see out of one but not the other. Heres why.
The Science of Us explains the process is pretty simple, and if you've deduced already that it's because one eye gets adapted to light while the other is still adapted to darkness, you're on the right track. They explain that two women in the UK went to the doctor complaining about this kind of transient blindness, and how they would wake up even after not using their phones for a while to find their vision diminished.
