Study shows increased outdoor activity in children reduces the development of nearsightedness. While LASIK and PRK laser vision correction eye surgery are highly effective in correcting nearsightedness — or myopia — in adults, it would be nice if we could stop nearsightedness from developing in the first place.
A recent study from Taiwan gives us a glimpse on how to stop nearsightedness from developing. In this study, two suburban schools of similar composition and similar socioeconomic status were compared, reflecting a total of 600 students ranging in age from 7 – 11 years. Both schools provided 80 minutes of recess daily. In the first school, children were allowed to play outside or stay indoors during recess. In the second school, children were not allowed indoors during recess, but had to play outdoors. By one year, children in the second school already were showing lower degrees of nearsightedness. Outdoor activity seemed to slow the overall rate of progression of myopia. Interestingly, outdoor activity seemed to halt myopic development in non-nearsighted children but did not stop the progression of nearsightedness in already myopic children.
