Four groups of office tasks were studied: Data entry terminals, conversational terminals, traditional office work and typing. Eye impairments are observed in every group of office employees, but the impairments are more frequent in VDU operators. The impairments persist during leisure time. High luminance contrasts between screen and source document are associated with an increase of eye troubles. Increased oscillating luminance of characters is associated with lower visual acuity, with a higher incidence of subjective and objective symptoms of eye irritation including more frequent use of eye drops.
数据录入终端、对话终端、传统办公室工作和打字。在每一组办公室员工中都观察到了视力损伤，但在视频显示终端（VDU）操作员中这种损伤更为常见。这些损伤在休闲时间也依然存在。屏幕与源文档之间的高亮度对比度与眼部问题的增加有关。字符振荡亮度的增加与视力下降有关，主观和客观的眼部刺激症状发生率更高，包括更频繁地使用眼药水。
