Myopia is a common disease of the eye, and the condition occurs most often in children or adolescents. The causes of myopia are complex and are influenced by a combination of factors such as genetics and environment. The exact pathogenesis of myopia is still unclear, but there are two main considerations: first, congenital genetic factors, such as the presence of high myopia in both parents, the child is more likely to develop myopia. Secondly, poor eye habits, such as prolonged excessive eye use, incorrect sitting and reading habits, excessive time spent using computers, cell phones and other electronic products, and short time spent outdoors, can all cause myopia. After the above-mentioned situation, you need to go to a regular hospital for an early optometry examination to clarify the degree, and then wear glasses in time to improve the corrected vision.
