Is this the cause of my myopia? Staying indoors too much looking at a computer screen? (just kidding) 😊 But this has been suspected and reported for several decades!
Or why do bookworms wear glasses more frequently than others.
"Spending at least two hours outside is one of the best ways to prevent children from developing near-sightedness, or myopia, according to ophthalmologists.
42% of people are myopic in the U.S.—up from 25% in the 1970s.
Up to 90% are myopic in East Asia by young adulthood.
Cause: Myopia occurs when the eyeball stretches, making faraway objects look blurry. But light stimulates the eye and releases dopamine, which can prevent stretching.
Policy in practice: Pei-Chang Wu, a Taiwanese ophthalmologist, convinced Taiwan’s Ministry of Education to send elementary school students outdoors for at least two hours daily.
Since the program’s implementation, myopia cases in primary school students have fallen for the first time in decades, from 50% in 2011 to 45.1% by 2015."
