Abstract: the eye has two important stages of rapid development. The first stage is 3-4 years old, and the second stage is adolescence, 12-15 years old. These two stages are called the “golden period” of visual development. The quality of adult vision is closely related to these two “golden periods”., The development of eyeball changes from small to large, and the anterior and posterior diameter of eyeball also changes from short to long. In terms of optical principle, people are highly farsighted at birth. With age, the eyeball is getting larger and the eye axis is getting longer. The vision of normal people will gradually change from hyperopia to emmetropia at the age of 18-20., The eye has two important stages of rapid development. The first stage is 3-4 years old, and the second stage is adolescence, 12-15 years old. These two stages are called the “golden period” of visual development. The quality of adult vision is closely related to these two “golden periods”. In the development of eyes, the younger the age, the faster the development speed.

In the first “golden period”, when children are 3-4 years old, although they are in the stage of hyperopia, if they are given long-time and close-up stimulation, such as watching TV, playing video games, reading, literacy, etc., they will inevitably accelerate the speed of eye lengthening.

and
myopia is mainly caused by the fact that long-term stimulation at close range will accelerate the change of eyes from hyperopia to emmetropia. In the first “golden period”, when children are 3-4 years old, although they are in the stage of hyperopia, if they are given long-time and close-up stimulation, such as watching TV, playing video games, reading, literacy, etc., they will inevitably accelerate the speed of eye lengthening. Similarly, children in the second “golden period”, that is, adolescence, too heavy schoolwork burden and too tired use of eyes will also speed up the lengthening of eye axis.

It continues to lengthen the axis of the eye in its growth and gradually forms myopia. If the child has developed to emmetropia or mild myopia in the first “golden period”, the degree of myopia will develop rapidly in the second “golden period”, resulting in high myopia.
