Researchers at Ohio State University find no link between bad eyesight and youngsters who spent most time in front of computer or television after 20-year study.

Sitting too close to a computer or television screen does not cause short-sightedness, scientists have concluded after a 20-year study.

Researchers at Ohio State University in the US followed 4,500 children between the ages of six and 11 over two decades, monitoring their screen use and testing their eyes.

Although current thinking suggests that staring too long at a screen can cause short-sightedness, or myopia, which has led to the recommendation of screen breaks, the new study found there was no link between bad eyesight and youngsters who spent the most time in front of a computer or TV.
