为确定中度近视是否与遗传有关及其遗传方式，笔者对鸡西市50例中度近视者的调查结果表明，中度近视遗传为(50.78±7.62)%。同样的环境因素，一级亲属中有近视者，更容易发生近视，对这样家庭的儿童，更应注意保护视力。 In order to determine whether or not moderate myopia is related to heredity and hereditary patterns, the author’s survey of 50 moderately nearsighted people in Jixi City showed that the hereditary degree of moderate myopia was (50.78±7.62)%.
