The correction method of refractive error in children requires not only effective, but also reasonable, practical, economic and harmless. The meaning of “correction” and “treatment” of refractive error is different, the former refers to optical correction (symptomatic), and the latter is the treatment of lesions (causal). Nowadays, the optical correction method includes glasses and surgery, and under the existing conditions, children are taken with glasses. Parents take their children’s “refractive error” notice to the hospital review, after the doctor’s examination, and dilated pupil examination, confirmed myopia, hyperopia or astigmatism, the doctor recommended glasses, many parents can not accept, the child so small to wear glasses ……, in addition to glasses Is there any other way? The answer from the doctor of the regular hospital is: about the treatment of refractive errors, especially myopia, a variety of advertisements, including qigong, massage, medicine, compresses, a variety of myopia treatment devices, etc., the treatment effect is not clear, but it can cater to those children who do not want to wear glasses and parents who do not want to fit their children with glasses because of various concerns, which often results in the best time for amblyopia treatment is delayed. If myopia, hyperopia, astigmatism, etc. are diagnosed by dilated eye examinations, they must be fitted with a pair of appropriate glasses, and they must also be reviewed regularly to check the fit of the glasses, check the changes in the refractive power of the eyes, and replace the glasses according to the changes in refractive state, refractive power, pupil distance, etc., in order to achieve reasonable correction. Because the body organs of children during the growth period, including the eyes, do not stop growing, some children need to replace their glasses in 3 months or 6 months, and this is the same reason as children get new clothes every year.
