"Based on the existing research, the occurrence and development of myopia mainly have two major influencing factors: genetics and environment." Professor Zhong Xingwu of Hainan Eye Hospital introduced that studies have shown that when the number of outdoor activities exceeds 3 hours a day, the child's myopia rate drops significantly. Natural light Is a key influence factor. Therefore, parents should remind their children to go outside after work. “Now children are very heavy in class and may not be able to guarantee an outdoor time of 2-3 hours. Outdoor exercise at different times is also effective for controlling myopia.†Zhong Xingwu also reminded, but too much outdoor light intensity can also cause eye damage. And do a good job of protection. Grinding wheel flint lighter
