If the child’s visual acuity of 4.7 is caused by refractive errors such as simple myopia, astigmatism, etc. or incomplete visual development, it is possible to regain a visual acuity of 5.0 after timely and effective correction and treatment. However, if the vision loss is caused by optic nerve atrophy, retinopathy of prematurity, etc., it is more difficult to recover.
If the child’s vision is only 4.7, he or she may be at a normal stage of vision development. Newborn babies have low vision, which can gradually improve with age. If a child is young, it is more likely that his or her vision has not developed to 5.0 and may improve to 5.0 as he or she ages.
If a child suffers from a high degree of myopia, astigmatism or other refractive errors, vision loss may occur, and the child’s visual acuity may improve to 5.0 after timely correction of the refractive error with appropriate eyeglasses.
However, if the child suffers from optic nerve atrophy, retinopathy of prematurity and other diseases, the treatment effect is poorer, and it is more difficult to restore the visual acuity to 5.0.
It is recommended that patients with visual abnormalities seek prompt medical attention to assess their condition and follow the doctor’s instructions for treatment.
