Prevention of high myopia All children have to go to school, and there is the possibility of myopia. Although ordinary myopia is not a disease, we must prevent high myopia! High myopia refers to myopia above 600 degrees, which may produce a series of pathological changes, such as glaucoma, vitreous opacity (floaters) and retinal detachment, and it is hereditary! Among these diseases, retinal detachment is the most serious. When patients encounter strong light or head vibration, they will feel that there are curtains in front of them (most obvious when squinting), tiny and numerous silver (or black) bright spots, red curtains ... In severe cases, there are cracked flashes, and further development may lead to blindness! Prevention should pay attention to two points: First, wear appropriate glasses after true myopia. If you don't wear it, you will squint desperately when you can't see clearly, which will increase the burden on your eyes and make your vision decline faster. Second, no matter how heavy your studies are, you should set aside enough time for physical exercise, outdoor farsightedness and outdoor activities. The myopia rate of American students is only 1/4 of that of China. Because they pay attention to fitness. This book is extremely serious and absolute about the consequences of high myopia. But in reality, only a small number of high myopia will have lesions, and most people are relatively healthy. For example, Bruce Lee, a kung fu superstar, and the Monkey King, a six-year-old boy, are all highly myopic. Even for people with serious diseases, only a few people will eventually go blind, and most people will be safe for life. Therefore, no matter what happens, we should face it with a positive, strong and optimistic attitude.
