1. Introduction:
According to statistics, more than 100 million Chinese primary and middle school students have myopia, and the Ministry of Education recently announced that in the past six months, it has conducted an investigation on the visual changes of primary, middle, and high school students in nine provinces, autonomous regions, and municipalities during the epidemic. The incidence of poor eyesight among students rose from 59.2% to 70.6%, an increase of 11.4%. Among them, 61.6% of primary school students, 80.3% of junior high school students, and 89.3% of high school students.
The National Health Commission has issued a notice confirming to launch the first batch of pilot projects for the prevention and control of myopia in children and adolescents in 182 districts and counties across the country, including Beijing, Tianjin, Shanghai, and Hebei, to alleviate myopia in primary and middle school students.
2. Analysis:
From the data, we can know that from elementary school to high school, the myopia rate of students has gradually increased. In particular, the rate of poor vision of junior high school students is 18.7% higher than that of primary school students, and the rate of poor vision of high school students is as high as 89.5%, which is shocking.
Although myopia has a small impact on our lives, it will affect our quality of life in the long run. Especially for high school students, if they are myopia, many majors cannot be taken, such as flight technology, precision instruments, criminal science and technology, and navigation. Technology and so on have certain requirements for vision.
What are the main causes of myopia in primary and secondary school students? I think these two reasons are probably .
First: Incorrect writing and reading postures
Writing and reading have a great impact on students’ eyesight. Many students didn’t pay attention at first, but after two years of elementary school, they became myopia. Like Hua Xiaomei in the first semester of high school I read the novel secretly in class, and watched it with a small flashlight while lying on the bed at night. I was short-sighted in 2 months. I regret thinking about it now.
Elementary school students are more naughty, writing generally is not the right posture, especially reading, they like to read on their stomachs, while junior high school students and high school students will be obsessed with reading novels, overuse their eyes, they will naturally be short-sighted over time.
Second: Mobile phones and TV are too harmful to students’ eyesight
For children playing on mobile phones or watching TV causes myopia, some parents must have a deep understanding. Now most parents do not control their children’s mobile phones in place, and some students play on mobile phones. You can play for a few hours, and the same is true for watching TV. The light from the screen is the most harmful to the eyes and the most likely to cause myopia.
It can be said that many children’s vision myopia is mainly played on mobile phones, playing games with mobile phones, watching TV dramas with mobile phones and even reading novels. They can play for two or three hours after playing. strange.
3, 3 suggestions to prevent myopia:
for children's vision myopia, in fact, it can be avoided. This requires parents to keep their children in good habits from the time they go to school. Hua Xiaomei will give you 3 suggestions to prevent children's vision myopia. .
01: Correct the children's writing posture and let them develop good habits.
Now many children do homework, and there are many bad habits, such as sideways, lying on their stomachs, head closer to the table, etc. These homework postures are obviously incorrect and correct His writing posture is "head straight, shoulders flat, body straight, and feet safe". Simply put, don't tilt your head, keep your shoulders consistent, sit upright, keep your eyes 35 cm away from the book, and don't move your feet.
This is convenient for children to develop a good habit of concentration, and a certain distance between the eyes and the table and books can prevent myopia, which is very beneficial to the child's physical and mental health. Parents can supervise and remind them to keep the child writing correctly posture.
02: Controlling the time for children to watch TV on mobile phones
mobile phones and TV are too harmful to children’s eyesight, but now children are really "addicted" to mobile phones and TV. Some children hold their phones to play games and watch TV series all day long. Parents Let it go, can the child not be nearsighted.
Therefore, parents must be cruel to control their children’s time to watch TV on their mobile phones. For example, they can watch TV for an hour and play on mobile phones for an hour every day. They can also use their academic performance to constrain their children. You can play mobile phones for two hours on weekends and so on. Parents and children must form three chapters of regulations and rules. This will not only effectively prevent children’s vision myopia, but also prevent children from indulging in playing mobile games.Can improve children's self-control ability.
03: A reasonable diet can also prevent myopia
In addition to correcting the child’s writing and reading posture, and controlling the child’s mobile phone time, it can also prevent myopia from the diet. You can let your child eat more foods containing calcium and chromium, because calcium and Chromium is the main component of the eyeball sclera.
For example, eating more broccoli can have a certain protective effect on eyesight, eating more spinach can prevent eye aging, eating more animal liver can relieve vision pressure, etc., of course, lamb bone soup, pig bone soup, milk, beans, shrimp skin Foods such as eggs, rapeseed and other foods can supplement the ingredients needed by the eyeballs, can enhance the toughness of the sclera, can also eliminate the tension of the eye muscles, relieve eye fatigue, and are very good for preventing myopia. Parents can let their children eat more. Z3z
4. Write at the end:
The number of students who have myopia is increasing. How to effectively prevent children’s myopia? In addition to let children develop good writing and reading habits, reduce the time spent on mobile phones and watch TV, and rationally match food, of course, you can also give your children more rooms For these green plants, don’t let your children write and read under strong light and weak light. More importantly, let them keep normal rest and avoid excessive eye fatigue.
Nowadays, many students have myopia. Most of them are caused by excessive study. They study at school, go home and do homework until late at night, and finally go to the tutoring class to study on a weekend, and the eyes are not fully rested. Dry eyes and astringent eyes slowly appear myopia. I hope that students in elementary and middle schools will arrange their time reasonably and combine work and rest to prevent myopia.
