摘　　要：目的了解视屏显示终端(VDT)作业人员的眼调节幅度状况,为VDT作业人员保护眼睛,预防与VDT作业相关的眼睛损伤提供依据。方法对596名5年以上VDT作业人员和572名对照者进行问卷调查和眼科检查,采用SPSS 11.5软件进行单因素分析以及直线回归模型分析。结果视屏显示终端作业者眼调节幅度较对照组降低,差异有统计学意义(P<0.01),年龄、工龄、每周工作时间、屈光状态、屏幕类型5个因素是VDT作业人员的调节幅度下降的重要易感因素。结论 VDT作业可使作业者眼调节幅度下降,屈光不正者从事VDT作业更容易引发调节幅度下降。而且有随作业人员工龄、每周工作时间的增长加重趋势。[Objective]To understand the amplitude of accommodation of video display terminal（VDT） operators,and provide evidence for eye protection of the VDT operators and prevention of VDT operation-related injury. [Methods]Questionnaires survey and eye examination were performed on 596 VDT operators with service length of more than 5 years and 572 normal controls.Single-factor analysis and linear regression model analysis were conducted by SPSS 11.5 software. [Results]The amplitude of accommodation of VDT operators was lower than that of controls,with significant difference（P〈0.01）.Age,service length,weekly working hours,dioptric situation and screen type were the predisposing factors of amplitude of accommodation decrease on VDT operators. [Conclusion]VDT operation can cause the decreasing of amplitude of accommodation the operators.The people with ametropia engaged in VDT work are much more likely to induce amplitude decreased,which may become worse with the extending of service length and weekly working hours.
