Childhood is the golden stage of visual development, which depends on parents' observation of children's daily life and finding abnormal visual development. Humans, like other mammals, are not born with binocular vision of 65,438+0.0. Only through a clear image on the retina can vision develop day by day.
Generally speaking, stereoscopic vision should be formed before the age of three, and then vision will continue to develop slowly to the age of five, and reach a mature stage after the age of ten. Therefore, it is suggested that parents can take their children to the ophthalmology department to check their vision development after they are three years old, so as to find problems and treat them as soon as possible. Regarding the development of preschool children's vision, the following are some observation points and health care methods suggested by experts for parents' reference.

2. Amblyopia refers to poor eyesight in one eye or both eyes. Even after correction (wearing glasses with the right degree), the best vision can't reach the vision that can be achieved at that age.
3. ametropia The so-called "ametropia" means that the naked eye vision can't reach the normal standard (usually 0.8), and it is not caused by other diseases and needs to be corrected through optical lenses (wearing glasses). Common ametropia problems include myopia, hyperopia and astigmatism.
4. Visual deprivation, such as congenital cataract, congenital ptosis or corneal opacity, will lead to poor visual function. In addition, children's congenital vision problems include congenital glaucoma, congenital cataract, congenital ptosis, amblyopia or color blindness. As for the problem of myopia that parents are most worried about, although the possibility of congenital myopia has been reported, according to epidemiological studies, the heritability of myopia patients is extremely low.
