Gelonghui, July 13? Zena Wudong Yushan, deputy director of the Disease Control Bureau of the National Health Commission, said at a news conference of the National Health Commission on the 13th that high myopia can easily lead to many serious complications, such as cataract, retinal detachment, glaucoma, and so on. A special survey of myopia conducted by the state from September to December 2020 shows that nearly 10% of myopic students are high myopia, and the proportion increases with the increase of grade. 1.5% of 6-year-old children in kindergarten are high myopia, and 17.6% in senior high school. The harm of high myopia can not be ignored.
