Myopia, or nearsightedness, affects approximately 25% to 33% of the population in the United States. There are no definitive causes of Myopia. One theory suggests Myopia might develop as a result of excessive accommodation or the changes in optical power to maintain a clear image (focus) on an object as its distance varies and uncoordinated ocular growth in response to prolonged near work. While there are many trials studying the effects of contact lenses and medication on children with Myopia, there are also lifestyle factors believed to impact nearsighted children. Playing outdoors might actually protect or slow the progression of myopia in children. The decreased accommodative demand outdoors, pupil constriction in bright light or the direct effect of light exposure may all contribute to the protective effect on children. Not only will playing outside contribute to healther, more active and happier children but also may improve their eyesight as well. So get outside and play!
