Normal values of children's vision

Children's visual acuity normal value may be 0.4-1.0, because different ages, specific visual acuity also exist differences.

Children's early optic nervous system has not developed perfectly, so most of them are lower than the normal standard of adults. For example, the normal value of visual acuity of 3-year-old children is 0.4-0.6; the normal value of visual acuity of 4-year-old children is 0.6-0.8
