Australian scientists have discovered a strange phenomenon. The incidence of myopia in Singapore and Australian Chinese is more than 20%. They are all descendants of Chinese. They all read English. Why is there such a big gap? Finally, scientists found Australian Chinese. Outdoor activities are much more than Singapore.


Australian scientists also conducted a three-year prospective study in Guangzhou, which allowed children to increase their outdoor activities for 40 minutes each day. The incidence of myopia was 9 percentage points lower in the experimental group compared with the control group in three years. Outdoor activities are considered to be protective factors for the independence of myopia. Therefore, young people must increase their effective outdoor exposure time and reduce the burden on their eyes.
