Abstract: outdoor sports have a protective effect on the development of myopia, but indoor sports have nothing to do with the occurrence and development of myopia; And even if there is no physical exercise outdoors, it still helps to inhibit the development of myopia.
myopia is one of the main causes of juvenile vision damage. Children’s vision affects the hearts of countless parents. How to prevent and control the high incidence of myopia has also become a topic of great concern to optometry experts at home and abroad.
in the white paper “national visual health” released this year, one in three people over the age of 5 in China is myopia. Among the total population over the age of 5, the proportion of myopia ranges from 35.16% to 39.21%. The total number of people with myopia ranges from 437 million to 487 million, of which the proportion of high myopia ranges from 2.33% to 2.47%, and the total population with high myopia ranges from 29 million to 30.4 million. The white paper points out that if effective policy intervention is not effective, the incidence rate of myopia in China over the age of 5 is expected to increase to 50.86% to 51.36% by 2020.
experts point out that the occurrence and harm of myopia are irreversible, not just wearing glasses. High myopia is prone to various fundus diseases, causing serious permanent damage to visual function, and can be complicated with various blinding eye diseases, such as retinal detachment, retinal degeneration, myopic macular degeneration, glaucoma, choroidal neovascularization, etc. The heritability and familial aggregation of myopia will affect the future population quality of our country. A study of
found that outdoor exercise has a protective effect on the development of myopia, but indoor exercise has nothing to do with the occurrence and development of myopia; And even if there is no physical exercise outdoors, it still helps to inhibit the development of myopia. Therefore, some experts pointed out that the protective effect of outdoor activities is not because it reduces the time of near vision activities, but is directly related to the length of “outdoor time”.
nowadays, children spend a long time in front of their desks every day, do not pay attention to outdoor sports, and pay attention to rest when using their eyes at close range, so as to delay the development of myopia. Excessive close eye use and eye use in static environment are easy to cause the decline of eye adjustment ability, resulting in myopia.
here also call on parents to spend more time with their children outdoors on weekends. Increasing outdoor activities for teenagers is not only good for eye health, but also good for physical and mental health. Adults can also relax after a week of intense work. If the child is found to have myopia or eye discomfort, he should go to the eye hospital for examination and treatment as soon as possible.
