A longitudinal survey in two different phases with an interval of 4 years (including more than 23,000 employees) has been carried out to study whether the time spent using VDU (daily hours and years of work) can change the refractive state. With reference to the whole sample including all refractions, there was no significant difference in the refractive state in employees who spent varying daily hours or years working at VDU. Furthermore, there were no significant changes in the refractive states of emmetropic, hypermetropic and myopic subjects, with regard to the time spent working at VDU. The data have shown that a high exposure to VDU work (more than 6 h per day or more than 6 years spent working at a VDU) is not responsible for inducing or worsening refractive error.
一项分两个不同阶段、间隔4年（涵盖超过23000名员工）的纵向调查已展开，以研究使用视频显示终端的时长（每日时长和工作年限）是否会改变屈光状态。对于包括所有屈光情况的整个样本而言，在视频显示终端上每日工作时长不同或工作年限不同的员工，其屈光状态并无显著差异。此外，正视眼、远视眼和近视眼受试者的屈光状态，在视频显示终端上的工作时长方面并无显著变化。数据表明，长时间接触视频显示终端工作（每天超过6小时或在视频显示终端上工作超过6年）并不会导致或加重屈光不正。
