How does child refractive error cause

Children's refractive error is generally caused by genetic factors, improper use of the eye, lack of outdoor activities and other factors.

1. Genetic factors

refractive error has a certain genetic tendency, if there is a history of refractive error in the family, the incidence of refractive error is relatively high.

2. Improper use of the eye

If the child does not develop good daily eye habits, such as reading, writing, or using electronic products for a long time, it may lead to excessive eye fatigue, which may cause refractive error.

3. Lack of outdoor activities

If the child lacks outdoor activities and exercise for a long time, staying indoors for a long time, resulting in insufficient rest and relaxation of the eyes, it will also increase the risk of refractive error.
