Some people think that “nearsightedness is better than farsightedness, farsightedness is better than farsightedness” and “glasses are for nearsightedness”, etc. In fact, these statements are incorrect. The so-called farsightedness is the reflection of the external scene into the refractive system of the eye, the focus falls on the back of the retina, can not be clearly imaged on the retina, look at the far and near are not clear. Many people with moderate to high hyperopia not only have low vision, but also have strabismus and amblyopia. Therefore, ophthalmologists believe that farsightedness is a more troublesome refractive error than myopia and should not be taken lightly. Farsightedness not only affects near and far vision, but also causes muscle fatigue, eye soreness, orbital pain, and dizziness due to long-term over-contraction of the internal rectus muscle, one of the regulating muscles. The child may have difficulty concentrating in class, have poor memory, and hate to read and write, resulting in a decline in academic performance. In farsighted eyes, the strengthening of their regulation will definitely increase the excitability of the internal rectus muscle. If the degree of hyperopia in one eye is serious, in order to make the eye see clearly, the adjustment must be increased, and the excitability of the internal rectus muscle must be increased compared with the normal eye, therefore, some hyperopic eyes form internal strabismus. Therefore, most strabismus is found in children with high hyperopia. Most of the patients with hyperopia with strabismus are used to work and study with their farsighted eye (the eye with low hyperopia) and leave the non-used strabismic eye aside, which will lead to amblyopia after a long time. Children with farsightedness should have their eyes examined and fitted with glasses as early as possible. If parents find that their children do not like to read books and complain that they feel blurred traces, eye swelling, headaches and poor academic performance after reading books for a long time, they must go to the doctor in time for an examination and examination of the shadow. If it is determined that the child is farsighted (including farsightedness and astigmatism), it is necessary to seize the golden opportunity to wear suitable glasses before the age of 8 years, do not delay. Otherwise, it will be very difficult to improve the vision after the age of 12, not to mention the restoration of binocular vision.
