A common culprit for the increase in myopia among children is something you have probably guessed: screen time. According to a 2018 American Optometric Association study, four in five parents say their kids spend at least an hour a day in front of a computer or mobile device. Miller argued that parents tend to grossly underestimate how much screen time their school-age child is actually getting. Doctors say that the constant up-close interactions might be leading to an elongation of the eye.
I have wondered for a long time the affects on eye sight of looking at a screens. You could chalk this up to the fact that we simply don't need to look as far in the distance as we once did. Evolution works both ways I guess.
