A New Finding in Myopia Research (IV): More Outdoor Activities Can Prevent Myopia

Early in 2000, epidemiological studies have shown that the more hours of outdoor activity per week myopic children have, the lower risk of developing myopia. Other studies have shown that children who are already myopic spent significantly less time outdoors than children who are not. Rose et al. found a correlation between myopia and the amount of time spent outdoors, and this was published in 2008 in the journal Ophthalmology. Rose’s team followed 4000 students in local primary and secondary schools over 3 years and found that children before 10 years old who spent a lot of time outdoors, either relaxing or playing sports, were less likely to develop myopia, and that indoor sports did not seem to work. In addition, Rose’s team did not discover evidence that close-up eye work was harmful to eyes, and even simply staying outdoors work. Follow-up studies done in China, Singapore and other countries support these results.
