1.本文报告受检中学毕业生2004人中经验光配镜确诊为近视者652人,发病率为32.5%。其中初中毕业生发病率为12.1%、高中毕业生为54.9%。由此可见近视发病率随学级升高而增加,其规律是初中阶段发展缓慢,到高中毕业阶段近视则大幅度上升。这是由于初中到高中期间课程日益复杂,近距离用眼时间不断增加,过久,因此眼的疲劳很不易恢复,是近视率明显上升的重要因素之一。 1. This report reports that 652 people were diagnosed with myopia by light microscope in 2004 with the rate of 32.5%. Including junior high school graduates incidence rate of 12.1%, 54.9% of high school graduates. This shows that the incidence of myopia increases with the school-level increase, the law is the slow development of junior high school, high school graduation stage myopia increased significantly. This is due to the increasingly complex course from junior high school to high school, with the eye time increases, too long, so the eye is very easy to recover from fatigue is one of the important factors in the apparent increase in myopia.
