October 12, 2017; by Mae Chan (NaturalBlaze.com) The ready availability of technology may make the children of today faster at configuring a new smartphone, but does all of that screen time affect the development of their eyes?
While conventional wisdom dictates that children should do less up-close viewing, sit farther from the television and perhaps even wear their eyeglasses less, we have found in recent studies that another factor may be at play: Kids need to go outside, and, if not play, at least get some general exposure to outdoor light.
To our surprise, more time outdoors had a protective effect and reduced the chances that a child would go on to need myopic refractive correction in the future. The size of the effect was impressive.
What causes nearsightedness?
Myopia, or nearsightedness, is a condition in which you can’t see far away but can see up close without glasses or contact lenses. It typically starts during the early elementary school years. Because kids don’t know how other kids see, they often think their blurry vision is normal, so regular eye examinations are important during childhood.
With myopia, the eye is growing, but growing too long for distant rays of light to focus accurately on the back of the eye. A blurry image results.
