‘Go play outside, kids:’ Natural light reduces risk of nearsightedness in children, scientists say November 30 2014
Scientists say the "outdoor effect" on nearsighted children is real: natural light is good for the eyes.
It's long been thought kids are more at risk of nearsightedness, or myopia, if they spend hours and hours in front of computer screens or fiddling with tiny hand-held electronic devices.
Not true, say scientists. But now there is research that suggests that children who are genetically predisposed to the visual deficit can improve their chances of avoiding eyeglasses just by stepping outside.
Yep, sunshine is all they need -- more specifically, the natural light of outdoors -- and 14 hours a week of outdoor light should do it.
