9-year-old children with hyperopia and amblyopia need active treatment to promote recovery. Some children can recover from amblyopia after about 1~2 years of treatment, but the degree of hyperopia cannot be recovered on its own, and it may be gradually reduced with age, but it cannot be completely eliminated. Amblyopia is caused by the lack of normal development of visual function in childhood, and farsightedness is an important cause of amblyopia. The treatment effect is better before the age of 6, and after the age of 6, the treatment effect will be reduced year by year with the growth of age, and the treatment is still effective in 9-year-old children, and the visual acuity can be gradually restored after 1~2 years of treatment, but it is difficult to return to normal completely. Hyperopia is related to congenital developmental abnormality. As the patient grows older, the degree of hyperopia may decrease year by year, but it is not necessarily able to be completely reduced to normal. However, it is not always possible to reduce the degree of hyperopia to normal. Moreover, the degree of reduction of hyperopia varies from patient to patient, and there is no way to predict it. It is recommended that children with hyperopia or amblyopia should be seen promptly for evaluation of their condition and treatment as prescribed by the doctor.
