1. When children are studying, they should first pay attention to the environment, whether there is enough light and whether they make full use of natural light. It is suggested that the balcony or window sill should be used as a regular study area for children. Natural light is very important for the protection of myopia.

2. Keep "one foot, one punch and one inch" when reading and writing, that is, the distance between the eyes and the book is about one foot, the distance between the chest and the desk is about one punch, and the distance between the fingers holding the pen and the nib is about one inch. Eye time should not exceed 40 minutes.

3. Keep your eyes one foot away from the book. When the reading distance is less than 30 cm, it is not the best focus adjustment, which will promote myopia. And after studying for half an hour, you must look far or do outdoor activities to prevent myopia.

Finally, writing also includes holding a pen. The correct posture is:

The thumb and forefinger are one inch away from the pen tip, the middle finger is below, the thumb and forefinger form a circle, and the ring finger and the little finger are hooked up and put under the middle finger.
