RESEARCH NOTE Eyestrain in VDU Users: Physical Correlates and Long-Term Effects
研究了荷兰电话查询服务员工在引入VDU前后及两年后的眼疲劳情况，发现抱怨的数量、类型和严重程度随时间无变化，验光测量无法预测抱怨且除老化外无恶化。
Subjects in the Dutch telephone inquiries services were studied just before, just after, and two years after the introduction of VDUs. Number, type, and severity of complaints did not change over time. Optometric measures were not useful for predicting complaints and showed no deterioration other than aging effects.
