Children often have myopia due to bad eye habits. Increasing outdoor activity time can be prevented

Abstract: the main influencing factors of myopia include environmental and genetic factors. If both parents are myopic, the probability of children suffering from myopia increases significantly. In addition, among children, myopia is caused by close work, incorrect reading and writing posture, poor visual environment, insufficient outdoor sports and nutritional factors.

, when a child is crying or disobedient, many parents will habitually plug their mobile phone and IPAD into their hands and let them calm down quickly. However, such a good method leads to premature exposure to electronic products and outdoor activities, which makes the incidence rate of myopia in recent years increase linearly. Associate Professor Yang Xiao, deputy director of refractive specialty of Zhongshan eye center of Sun Yat sen University, said that the problem of excessive eye use of children is inevitable. Therefore, it is suggested to increase some outdoor activities. Studies have proved that adding a 40 minute extracurricular exercise can effectively reduce the cumulative incidence of myopia of students by 9.1%.

the prevalence of myopia in primary and secondary schools in China ranks second in the world.

in recent years, the prevalence of myopia in primary and secondary schools in China remains high and increases year by year, second only to Japan, ranking second in the world. According to the results of national student physique monitoring in 2010, the detection rate of myopia is 40.89% for primary school students, 67.33% for junior high school students and 79.2% for senior high school students.

why do so many children suffer from myopia? Ophthalmologists said that the main influencing factors of myopia include environmental and genetic factors. If both parents are myopic, the probability of children suffering from myopia increases significantly. In addition, among children, myopia is caused by close work, incorrect reading and writing posture, poor visual environment, insufficient outdoor exercise and nutritional factors.

avoid myopia? Ophthalmologists pointed out that the main thing is to improve the bad eye habits. Even if the parents are highly myopic, as long as the children maintain good eye habits, their eyesight can be well controlled. “Taking myself as an example, my husband and I have deep myopia, so we will deliberately control their eye habits since childhood. Now their eyesight is 1.2.” Experts from

control the duration of watching TV, playing mobile phones, using computers and other electronic products. The screen of electronic products has strobe. Focus on the screen, Blinking (blinking) times will be reduced. Over time, it will lead to dry and uncomfortable eyes

Avoid using eyes closely for a long time. Do not read, write, watch and other close work for a long time. Use your eyes for about 30-45 minutes, rest for 5-15 minutes, and look far or close your eyes. Long time close work of eyes will cause adjustment spasm. If they are not relaxed in time, they will form myopia. The continuous close gaze time should not exceed 45 at a time. Children are mostly myopia due to bad eye habits. Increasing outdoor activity time can prevent

insist on outdoor sports in the sun. A study in Singapore shows that an increase of 1 hour of outdoor activities every day will increase the diopter by 0.17d and reduce the eye axis by 0.06mm. The study of Zhongshan Eye Center shows that an increase of 40 minutes of extracurricular exercise every day can effectively reduce the cumulative incidence of myopia of students by 9.1%
