You've probably heard how you're not supposed to stare at your phone or iPad screen in the dark for too long, because the bright light is bad for you or something. HERE'S the "or something."
A 26-year-old guy in China just wound up with a DETACHED RETINA from texting in the dark too much.
The guy would text with his girlfriend for several hours in bed. It wound up putting a ton of strain on his retina . . . and he needed emergency surgery to have it reattached.
Your retina is light-sensitive and sends messages to the optic nerve in your brain. And if you strain it too much, it can detach. Apparently staring at your super-bright screen in the dark can be enough to cause those problems.
Now . . . this guy was the exception. You probably WON'T wind up having such a severe issue from texting in the dark. But it's a warning not to overdo it . . . because if you take it too far, you could wind up having problems.
