Preventing myopia mainly includes rational eye use, increasing outdoor activities, and adhering to eye massage. 1. Reasonable eye use: we need to avoid long time close reading, especially avoid long time looking at cell phones, computers and other electronic products. When reading, you need to have a correct posture and bright light. After 30-40 minutes of close reading, look into the distance for about 5-10 minutes. 2. Increase outdoor activities: Light exposure can promote the body’s secretion of dopamine, slowing down the growth of the eye axis, so it is recommended to do more outdoor activities to prevent myopia. 3. Insist on eye massage: Massaging the eye area can relax the eye and relieve fatigue, thus playing a role in preventing myopia. It is recommended that myopia patients consult a doctor in a timely manner to assess their condition and follow the doctor’s instructions for treatment.
