June 6th is the 22nd National Eye Care Day. As the old saying goes, the eyes are the windows of the soul, which shows the importance of the eyes. However, the incidence of myopia among adolescents in China is increasing year by year.

"Eyes" bathed in sunlight can prevent myopia.

Zhang Jinsong, dean of the Eye Hospital of China Medical University, said that children should go out to bask in the sun more on weekdays. "Eyes" bathing in the sun does not mean looking directly at the sun, but implies that people should always be active in the sun. The human body will produce a special hormone called dopamine, which has an inhibitory effect on the brain and can prevent myopia. In addition, you can wear orthokeratology glasses or use atropine eye drops with a concentration of 0.02%, which are good ways to effectively prevent myopia in children.

Zhang Jinsong said that almost 40%-50% of students in primary schools in China are nearsighted, 60%-70% in high schools and 80% in universities. However, many parents usually choose glasses smaller than their children's eyes when wearing glasses for their children. Parents' ideas are very direct, and they are afraid that their children will wear glasses with just the right degree and their eyes will continue to grow. Actually, this is a misunderstanding.

Zhang Zhiyuan Jinsong explained that if myopia is 200 degrees, but myopia is corrected with 100 degrees, the remaining 100 degrees is still invisible, and overuse of eyes will continue, leading to further development of myopia.
