In most cases of farsightedness in young children, it is most often caused by genetic factors. Farsightedness is a refractive state in which parallel light rays from the outside world are focused behind the retina after passing through the refractive system of the eye when the eye is adjusted at rest. The clinical manifestation of farsightedness in children is that they do not see clearly at a distance and do not see clearly at a distance. Generally, hyperopia is associated with genetic factors, but also with corneal disease, lens disease, and ocular tumors. In clinical practice, the most important factor in the development of hyperopia in young children is the genetic factor. If a child is hyperopic, the degree of hyperopia must be checked carefully, because high hyperopia can lead to amblyopia. Therefore, once the diagnosis of hyperopia is confirmed, active treatment should be given. Usually, children with hyperopia should consider wearing appropriate farsighted glasses to correct it.
