青少年正处生长发育时期,眼睛及其视力与身体其他器官一样,也有一个成长过程。近年来发现中小学生视力减退到5.0以下者(等于标准视力1.0以下)的比例逐渐上升,学生近视发病年龄不断提前。1979年卫生部委托辽宁省卫生局召开的“全国青少年近视眼防治科研课题”工作会议,要求进一步开展对影响近视眼发生因素的研究。为摸清我省青少年视力变化情况,其中包括少数民族青少年的视力状况,我们于1981年3月及10月对我省西宁地区汉族,黄南藏族、互助土族在校青少年学生进行了视力调查。
Young people are in the period of growth and development, the eyes and their eyesight, like other organs in the body, have a growth process. In recent years, primary and secondary school students found that vision loss to less than 5.0 (equivalent to standard visual acuity below 1.0) gradually increased the proportion of students, the incidence of myopia continues to advance. In 1979, the Ministry of Health commissioned Liaoning Provincial Health Bureau to hold a working conference on “National Research Project on Prevention and Treatment of Myopia of Children and Adolescents,” and requested further research on the factors that affect the occurrence of myopia. In order to find out the changes in the visual acuity of adolescents in our province, including the visual acuity of ethnic minority adolescents, we carried out the visual acuity survey of Han and Huangnan Tibetan and Tuzhu adolescents in Xining Prefecture in March and October 1981.
