What are the methods for preventing myopia?

Methods for preventing myopia mainly include the following points: 1. Proper eye use posture: Maintain a distance of at least one foot (about 30 cm) between the eyes and reading or writing materials, and avoid prolonged close-up visual tasks. 2. Control duration of eye use: Avoid excessively long continuous periods of near work. It is recommended to take a 10-minute break every 40 minutes, during which you should look into the distance or close your eyes to rest. 3. Appropriate lighting: Choose a learning environment with soft and stable lighting; avoid reading in overly dim or excessively bright light. 4. Balanced diet: Consume more foods rich in vitamin A and carotene, such as carrots and animal liver, which help maintain lens elasticity and support retinal development. 5. Increase outdoor activities: Spending more than 10 hours per week outdoors helps relax eye muscles and prevent myopia. 6. Regular vision check-ups: Adolescents should have their vision tested annually to detect and correct vision problems early.
