Methods to prevent myopia generally include good eye habits, increasing outdoor activities, and regular checkups. 1. Good eye habits: Minimize the use of electronic products in daily life, keep a proper distance when reading, don’t use your eyes for a long time, and look away to relax after using your eyes for a period of time. 2. Outdoor activities: appropriate outdoor activities, looking into the distance, under the action of natural light, can promote the retina to release dopamine, can reduce the risk of eye axis growth, and thus can prevent the development of myopia. 3. Regular checkups: Regular eye checkups can be done in the hospital to understand the development of the eyes and to intervene in time to avoid further deterioration once there is a decrease in myopia. Myopia can be effectively prevented through good living habits and rational eye use. If there is any discomfort such as blurred vision, you should seek medical attention promptly.
