With the changes in the current social environment, more and more children are suffering from farsightedness. Many parents once found that their children have farsightedness, in order to save money, often in some unknown small optical store for children with glasses, do not know, children with farsightedness is to pay attention to the method of prescription, incorrect prescription may lead to the deepening of farsightedness, affecting the development of the eye. 1, low farsightedness, that is, 300 degrees or less preschool children, normal or near-normal vision, no visual fatigue symptoms can be temporarily without glasses. 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 ~ 100 degrees. 2.Middle and high hyperopia, i.e. more than 300 degrees, 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, after adaptation, give the prescription for the second pair of glasses in proportion to the full degree of farsightedness according to the optometry results. 3.People who have internal obliquity of the eye should, in principle, be equipped with the full degree of hyperopia. Especially for those who have completely corrected or basically corrected their internal obliquity and obtained monovision in both eyes after wearing the glasses, even if their vision is reduced after wearing the glasses, they should be prescribed with the full prescription. If the eye position does not improve 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 the beginning, and after you get used to it, you can get the full prescription again.
