The Impact of Outdoor Time on Myopia Development
Myopia, or nearsightedness, shows reduced development rates after the age of 20-25, yet about 10% of the population may still experience worsening prescriptions. Various studies indicate that spending 90 minutes to two hours outdoors can mitigate the onset and progression of myopia in children. The underlying mechanisms remain unclear, with possibilities including the effects of sunlight, brightness, or specific wavelengths of light on the retina. Research into light's focus on the retina outdoors suggests it sends different signals than indoor environments. Current studies utilize health trackers for more accurate data on outdoor exposure. Investigating additional factors like vitamin D and physical activity exists, with evidence from Taiwan's policies mandating outdoor time correlating with decreased childhood myopia rates. However, debates continue regarding the effect of outdoor time on myopia progression, with some analyses showing only significant impacts on delaying myopia onset rather than its progression.
