Develop a correct posture
To cultivate children's correct reading and writing posture, the distance between eyes and books should be about 30 cm.
Medium brightness
When reading and writing, the light should be moderate, neither too strong nor too dark, and the light should come from the left front to avoid the shadow of the hand blocking the line of sight.
Rest at the right time.
Reading time should not be too long. Every 40 ~ 50 minutes, rest for 10 ~ 15 minutes, close your eyes or farsightedly for a few minutes or do eye exercises to prevent eye fatigue.
Avoid fuzzy handwriting
Don't read books and newspapers whose handwriting is too small or fuzzy, and don't write too small.
Correct bad habits
Educate children to correct unreasonable eye habits, such as lying on the table, reading or writing with their heads tilted, reading in bed, reading at meals, reading in bright or dim street lights and moonlight, reading in a moving car, walking, etc. These bad habits will make the eyes excessively tired and reduce the acuity of vision.
