When using the computer, keep the distance between the eyes and the computer screen at about half a meter, the computer screen is slightly inclined, and the screen brightness should not be dazzling and can be seen clearly without effort. The posture is to sit upright, try not to lie down, lie down, or look at the electronic screen.

3. Remember the “20:20:20” formula:

Remember: for every 20 minutes of reading or looking at the computer up close, look up 20 steps (about 6 meters away) away for 20 seconds .

4. Increase outdoor activity time:

Outdoor activities mainly emphasize activities in the sun. For children who are growing and developing, it is recommended that they be no less than 2 hours a day .

5. Balanced and comprehensive nutrition:

The diet should be balanced, not picky eaters, not partial eclipse, it is recommended to eat less sweets, eat more vegetables. In addition, animal liver foods are good for the eyes, so you can eat more.

When reading and writing, the sitting posture should be “head straight, shoulders level, body straight, and feet safe” , and at the same time pay attention to maintaining “one foot, one punch and one inch” : eyes one foot away from the book, chest one punch away from the table, and hands one inch away from the tip of the pen.
