In our work, whenever a child notices a decrease in vision, and our doctor tells the parents after examination that your child is nearsighted, the parents are very anxious and keep asking us, can the child’s nearsightedness return to normal? Can myopia be normalized without glasses? Can myopia be controlled with glasses? Parents do not want to see their children wearing glasses, but myopia is indeed a disease with a relatively high incidence among children. The number of myopia in China is nearly 400 million, and the number of teenagers is about 270 million, among which the incidence rate of myopia is 40.89% for primary school students, 67.33% for junior high school students, and 79.20% for senior high school students, so China is a real myopic country. Myopia is not just bad eyesight, myopia is actually a disease. Myopia is actually a disease, because the amount of myopia will continue to grow during adolescence, and some cases of malignant myopia will even grow in adulthood. Myopia can also cause other eye problems, such as vitreous clouding, fundus changes and retinal detachment. The cause of myopia is primarily genetic, followed by environmental factors, habits and lifestyle. In the farsighted society, people need to look far to catch food, so the eyes are adapted to look far, and in the modern information society, reading a lot to learn knowledge to be successful, so the eyes can only be adapted to look close. The survey shows that children who read more than 2 hours a day have 1.5 times the chance of developing moderate to high myopia than children who read less than 2 hours, and the possibility of myopia in children whose working distance is less than 30cm is 2.5 times that of children whose working distance is more than 30cm. Myopia is also closely related to the level of education, the earlier the child receives schooling, the greater the likelihood of myopia, or because of early reading and writing, long hours of close eye use. On the contrary, for every additional hour of outdoor activity per day, the refraction is skewed towards hyperopia by 0.17 degrees. Diet is also a key reason, in the past the traditional food to rice noodles and grains as the main, in recent years, dietary habits change, eggs and milk meat and fine food increased, belong to the high-calorie delicate food, may have a certain relationship with the development of myopia.
