Abstract: there are many reasons for ametropia in daily life. After all, it is an eye disease. Therefore, as long as the factors that can cause damage to the eyes can cause ametropia. Here is a detailed introduction to the factors causing ametropia., What is ametropia? At present, the number of people suffering from ametropia diseases in China is increasing, but not many people really understand ametropia diseases. In fact, ametropia is a common eye disease, including hyperopia, myopia and astigmatism. Here is a specific introduction to ametropia., Ametropia: when the eye is relaxed, the parallel light cannot clearly focus on the retina and can not see the external objects. It includes myopia, hyperopia and astigmatism., What factors can cause ametropia and what factors can cause ametropia? There are many reasons for ametropia in daily life. After all, it is an eye disease. Therefore, as long as the factors that can cause damage to the eyes can cause ametropia. Here is a detailed introduction to the factors causing ametropia., 1. Using computers: our study, work, life and entertainment are almost inseparable from computers. This is a close-up illuminant. As the most frequent tool for us to use our eyes at close range, computer is also the source of the greatest fatigue to our eyes. The survey shows that there are 82. 4% of computer users suffer from computer vision syndrome. It is characterized by dry and painful eyes, decreased vision, dizziness, sore neck, etc. In the United States, this is ranked first as an occupational disease! Therefore, reducing eye fatigue with computers should also be put in the first place in our human eye protection!, 2 reading and writing: the coverage is very wide. We need to learn from childhood. In memory, our myopia deepens with the progress of learning. Reading and writing are completed by close-up fine vision, which mainly depends on visual pyramidal cells. The excessive fatigue of visual cells will lead to the fatigue of the whole visual system, and the corresponding pathophysiological changes will occur in the eye muscles and eyeballs., What is

Children have a very high probability of myopia. Therefore, experts suggest that both parties with high myopia had better not get married. Have a fever of
