Clinically, there is no best way to prevent and control myopia. At present, myopia can be prevented and controlled by developing good eye habits, avoiding overuse of eyes, and increasing time for outdoor activities. 1. Develop good eye habits: Myopia is a kind of refractive error, and myopia can be induced by bad eye habits such as using eyes at close range for a long time. Therefore, you should develop good eye habits such as controlling the distance between your eyes and reading books in a well-lit environment. 2. Avoid excessive use of eyes: With the change of lifestyle and the diversification of electronic products, the daily use of electronic products by individuals is also increasing. Prolonged use of electronic products will lead to eye fatigue, which may cause myopia or aggravate myopia, so the time of using electronic products should be appropriately reduced to avoid overuse of eyes. 3. Increase the time of outdoor activities: Prevention and control of myopia can be realized by increasing the time of outdoor activities, such as two hours of outdoor activities every day or ten hours of outdoor activities every week, which can help prevent the occurrence and deepening of myopia. When there is no myopia, it should be actively prevented. After myopia, the deepening of myopia should be avoided, and it is necessary to go to regular hospitals to review the vision regularly.
