After a series of examinations such as objective optometry, mydriatic optometry, primary optometry and visual function examination, the optometry results obtained by myopic children and adolescents cannot be used as a prescription for childrens eyeglasses. First of all, wear glasses to adapt to the main, such as a child's first examination, medical optometry results for myopia 600 degrees, if he wears 600 degrees of myopia glasses at the beginning, it is difficult to adapt, often appear dizziness and other discomfort symptoms, you can wear low degree glasses first, adapt to then make up the number of degrees. In addition, the prescription of lenses can be determined based on the results of visual function tests (lens adjustment function, pupil convergence and dilation function, and eye position). For example, myopia combined with exobliques should wear glasses with foot correction, and myopia combined with exobliques should wear glasses with less correction. The selection of the prescription is to meet the clear, comfortable and lasting eye needs of children and adolescents after wearing glasses.
Whether to wear glasses for myopia needs to be decided after combining many factors such as diopter number, binocular balance, eye position, adjustment function, and collection function.
Usually whether to wear glasses with myopia to consider two factors: to see far vision and whether to maintain normal binocular vision function.
In general, children and adolescents with myopia below 75 degrees, naked eye vision is more than 0.6, usually use the eye on life and study does not have much impact, you can not wear glasses, but need to pay more attention to outdoor activities and eye health, to prevent further growth of degrees. For children and adolescents with myopia above 75 degrees, they often need to wear glasses, usually wear them or only wear them in class and when looking far, they need to refer to the degree of myopia and visual function.
People with low myopia, less than 200 degrees, have normal visual function and eye position during optometry, and do not have astigmatism. They can choose to wear glasses in class or when looking far away, and remove glasses when looking close or doing homework. But if there is exobliquity, you need to look far, look near often wear a mirror. More than 200 degrees of medium and high myopia, see far, see near are not clear, should wear glasses, wear appropriate glasses can improve the daily learning and life required visual quality; If the degree of astigmatism is high, no matter how many degrees of myopia, see far, see near are not clear, you need to often wear a mirror.
