Next time someone teases you about wearing glasses, strike back with this fact: intelligent kids are twice as likely to be short-sighted.
Researchers in Singapore examined the eyesight and intelligence levels of
1,204 children aged 10 to 12.
They found that the brightest kids were twice as likely to be short-sighted than children who weren't too clever.
Previous studies have linked the amount of time kids spend reading to whether or not they have poorer eyesight.
