Children under the age of 7 are generally hyperopic, and the eye axis gradually becomes longer with age, if the development is normal, the adult is orthopia, if the eye axis is shorter than normal is farsighted, greater than normal is myopia. farsightedness before the age of 7 is a normal physiological phenomenon, generally can not be corrected, but if there is strabismus or vision loss must be corrected with glasses, it should be timely prescription. Children’s farsightedness prescription principle Before children’s farsightedness prescription, must be first ciliary muscle paralytic dilation pupil, fully dilated pupils under the conditions of optometry. Children with hyperopia should follow the following principles: 1. Low degree hyperopia. That is, preschool children with less than 300 degrees, normal or near-normal vision and no symptoms of visual fatigue can be temporarily excluded from the prescription. Because many children have 300 degrees of physiological hyperopia. Those who have symptoms of visual fatigue should be fitted with glasses if they can improve their vision after wearing them. But not necessarily with enough, can retain 50 to 100 degrees. 2.Medium height hyperopia. Such children have different degrees of vision loss in both near and far vision, and most of them have vision fatigue symptoms. The prescription can be done in stages. First, wear glasses with a slightly lower degree of farsightedness than that obtained from the optometry, and then give the prescription for the second pair of glasses according to the proportion of all the degrees of farsightedness according to the optometry results after adaptation. 3.People with inward slant of the eye. In principle, it is necessary to fill in the full amount of farsightedness, especially for those who have completely corrected or basically corrected the internal obliquity and obtained monovision in both eyes after wearing the glasses, even if the vision is reduced after wearing the glasses, it is necessary to fill in the full amount according to the doctor’s prescription. If the eye position does not change temporarily after wearing glasses, and the vision loss is obvious, and you can’t see the blackboard in class, and you have difficulty walking, you can wear lighter glasses at first, and after you get used to it, you can get the full prescription again. Usually, there is always some discomfort when wearing glasses for the first time, but usually you will get used to it after wearing them for more than 2 months. After wearing the glasses to adapt to insist on wearing often to remove, and often check the visual acuity, with amblyopia to often cover the healthy eye and training the affected eye, so that the patient’s vision back to normal.
