根据学生近视是由于睫状肌长期紧张收缩而产生痉挛,使晶体凸度增大,屈光力过强,久之,由假性近视发展为真性近视这一发病机理,参考国内外资料,结合多年的工作实践,我们研制了《防治近视眼肌训练图》(1992年获国家专利,专号91301452.4),用以防治中小学生近视,现将应用此图防治的实验效果报告如下: 1 对象和方法1.1 临西县一中、二中都是地区重点中学,分别位于 According to the student myopia is due to long-term tension contraction of the ciliary muscle produce spasms, so that crystal convexity increases, refractive power is too strong, a long time, the development of true myopia from pseudo-myopia pathogenesis, with reference to domestic and foreign information, combined with years of work Practice, we developed the “prevention and treatment of myopia muscle training map” (1992 by the national patent, special No. 91301452.4), to prevent primary and secondary students myopia, the application of this figure will now control the experimental results reported as follows: 1 objects and methods 1.1 Pro Xixian one, two are regional key middle schools, respectively
