Abstract: the causes of myopia are mostly caused by genetic and environmental factors. When the eye is relaxed, the parallel light passes through the refractive system of the eye and focuses in front of the retina, resulting in unclear imaging of macular fovea. Care for your eyes and stay away from myopia., Now many primary school students put on glasses early, which has shown that the phenomenon of myopia is becoming more and more serious. At present, high-tech products such as smart phones and computers are full of attraction to these children, resulting in excessive eye use and the formation of myopia, which is the main reason for the formation of myopia. The specific causes of myopia are not very clear. Today, let’s talk about how myopia is formed and how to effectively prevent myopia., The causes of myopia are mostly caused by genetic and environmental factors, but according to the current situation, there are more myopia caused by environmental factors. Myopia is that when the eye is adjusted and relaxed, the parallel light passes through the refractive system of the eye and focuses in front of the retina, resulting in unclear imaging of the fovea of the retina. At present, it is divided into true myopia, pseudomyopia and mixed myopia according to whether the eyes participate in regulation. In fact, the causes of all myopia are the same, but it is pseudomyopia. After atropine mydriasis examination, myopia will disappear and appear as emmetropia or hyperopia., The main symptom of myopia is weak hyperopia, but good near vision, that is, you can’t see the distant objects clearly, and your eyes will also be tired and deviated. In fact, concave lenses are used to correct both true myopia and mixed myopia. At present, the methods of myopia correction such as frame glasses and contact lenses are relatively mature treatment methods. Of course, there are two methods: corneal plastic surgery and refractive surgery. Drugs can also be used to control myopia and prevent the degree from deepening., How to effectively prevent myopia is not very clear about its formation mechanism, but it is known that it is related to genetic factors, but the acquired bad eye habit is the real culprit. Therefore, in order to protect our eyes, we should use our eyes appropriately. At night, we should not use computers and mobile phones in rooms with too dark light, especially playing with mobile phones in bed, which will deepen the degree of myopia.,
