How much farsightedness 800 degrees at 4 years old is usually corrected per year

A 4 year old patient with 800 degrees of hyperopia is generally more difficult to reduce with correction, but as the child ages, a reduction in the amount of hyperopia may occur.
Hyperopia is a type of refractive error. A child is usually born with 300 degrees of hyperopia, which is physiologic and decreases with age. The current 4 year old child has 800 degrees of hyperopia, which is high hyperopia, pathologic hyperopia, and generally does not go away, but may decrease with age, but it is not clear how much each year.
Hyperopia can lead to vision loss, and children can wear glasses to correct hyperopia in order to improve their vision, but wearing glasses cannot reduce the degree of hyperopia.
It is recommended that children with hyperopia be seen in a hospital for evaluation of their condition and treatment as prescribed by the doctor.
