The myopia rate in China is close to 30%, primary school students suffer from myopia, the myopia rate in junior high school has soared to high school students wearing glasses, and the myopia rate of college students is as high as 80%.
There are many causes of myopia, according to our guess, the factors that cause myopia are: genetic factors, environmental factors, individual factors, nutritional factors and sleep factors. The main causes of myopia in primary school students are doing homework too late, lack of sleep, excessive TV and computer play, and intake of a lot of German protein.
There is now a high rate of myopia among elementary school students. Although there are some genetic factors for myopia, it is more important to influence external factors. At present, there is no more effective way to do it than wear glasses, but to carry out preventive measures in a lasting way.
Although there is a certain relationship between the extremely high myopia rate of middle school students and the current education system, it is more due to eye habits that lead to the occurrence of myopia. The focus of myopia prevention is also to develop good eye habits.

IV. Conclusion 1On the whole, students with heavy homework load accounted for the majority, and the homework burden increased with the increase of grade.
2.No matter what grade they are, they don't have a good rest for their eyes when doing homework; The school break time once again showed a decreasing trend with the increase of grades.
3.Anti-fatigue eye drops and eye exercises are both effective on the eyes, but they have not attracted the attention of students.
4.Although the number of people who are nearsighted is much higher than the number of people who are not myopia, a significant proportion of people do not wear glasses. This shows that students do not pay enough attention to the problem of myopia!
5 Among them, we can strive to overcome and correct the wrong factors, such as wrong posture and improper use of eyes. Things like the light is too dim or too strong, we can adjust it; We can try to avoid things like improper protection, improper medication, etc.; ......

Survey Results:
Through the survey, it was found that the myopia rate of middle school students is increasing today, and the phenomenon of myopia is not taken seriously by middle school students. Some people even think that if you are nearsighted, you can't wear a pair of glasses. It doesn't matter if you're nearsighted, and you make mistakes.
Many people often blame it on bad eye habits, such as reading books at an inappropriate distance, too little light, and long-lasting eye use. However, medical studies in recent years have shown that unbalanced diet, lack of sleep, noise, etc., are also important factors that induce myopia in adolescents.

The research report on myopia reads as follows:
According to the Internet research, the factors that cause myopia are: genetic factors, environmental factors, individual factors, nutritional factors and sleep factors. At present, the myopia rate of primary school students and high school students has reached 70%, and the number of patients has exceeded 60 million, and the number of blind people due to myopia has reached 300,000.
Vision loss directly affects our learning and hinders our physiology and psychology to varying degrees. According to the survey, the incidence of myopia among students in China is close to 60%, ranking first in the world.
After collecting information on the Internet, we learned that the incidence of myopia among primary school students in China is that of middle school students and high school students. It can be seen that with the increase of grades, the incidence of myopia is getting higher and higher.
Moreover, wearing glasses for a long time will lead to inconvenience in the work of Shengji Xun. Moderate to high myopia, especially high myopia, is prone to cause vitreous opacity, retinal hemorrhage and detachment and blindness. According to a survey report, there are more than 300,000 blind people due to high myopia in China, second only to Baiboqiao, a cataract, and glaucoma ranks third.
Dangers of myopia:
1. Vision loss: The eyes of myopia patients are mainly due to abnormal visual imaging caused by the long eye axis or the curvature of the cornea, and the ability of eye accommodation is reduced, resulting in clear near and blurred vision in the distance. If not timely**, myopia will gradually worsen, resulting in continuous vision decline, which will seriously affect daily life and work and study.
2. Retinopathy: The higher the degree of myopia, the greater the pressure on the retina. Long-term high myopia can cause retinal lesions, including retinal tears, retinal detachment, etc., and even lead to blindness.
3. Affect physical and mental health: myopia patients have long-term exposure to electronic products such as computers, mobile phones, etc., which will lead to eye fatigue and easily cause physical discomfort such as headache, cervical spondylosis, and lumbar spondylosis. At the same time, myopia can also lead to psychological problems, such as anxiety, depression, etc.
4. Cause eye diseases: myopia can cause symptoms such as eye fatigue, dryness, redness and swelling, and it is also easy to cause other eye diseases, such as conjunctivitis, keratitis, etc.
