Abstract: cultivate good eye hygiene habits and correct writing and reading habits. Books should be kept at a distance of more than 33 cm from eyes, and the continuous eye use time at close distance should not exceed 45 minutes, so as to reduce the use of computers and mobile phones and watch less TV. Pay attention to the pen holding posture, and the fingertips and pen tips shall not be less than 3cm.

myopia is a kind of ametropia, which shows that you can see things near but can’t see objects far away. When myopia is at rest, the parallel light from infinite distance, refracted by the refractive system of the eye, gathers into focus in front of the retina and cannot form a clear image on the retina.

adolescents aged 3-14 are in a critical period of physical development and growth, and they are also prone to myopia. If it is not for genetic factors, it is easy to cause myopia because they do not pay attention to their eye habits.

The incidence of myopia in children with less outdoor time and long close-up working time is 2.3 times that of children with more outdoor time and short close-up working time.
