Using your eyes at close range for a long time is one of the main causes of myopia. It is recommended to follow the "20-20-20" principle: every 20 minutes of using your eyes, look up at an object 20 feet (about 6 meters) away for 20 seconds to relieve eye fatigue.
2.Increase outdoor activities
Research shows that at least 2 hours of outdoor activities a day can effectively reduce the incidence of myopia. Natural light in the sun can stimulate the retina to release dopamine, inhibit the growth of the eye axis, and thereby prevent myopia.
3.Use electronic devices wisely
Blue light from electronic devices can cause damage to your eyes. It is recommended to turn on eye protection mode and maintain an appropriate distance (at least 30 cm) when using electronic devices.
4.Maintain correct reading and writing posture
Correct reading and writing posture is crucial to preventing myopia. The following are recommended reading and writing postures:
| Project | Standard |
|---|---|
| Distance between eyes and book | 30-35cm |
| Table and chair height | One punch between chest and table |
| light intensity | 300-500 lux |

Lack of certain nutrients in the diet can also affect vision health. The following are recommended foods:
| Nutrients | food source |
