A selected group of VDU workers were tested in an attempt to achieve objective evidence of visual fatigue and to identify a preferential monitor/gaze position during a particular work setting. Each subject was scored in a two-phase test. The highest mean scores were achieved when the monitor was lowered with respect to the primary/gaze position; the scores obtained with the monitor in primary or upward gaze position were significantly lower (p < 0.001). The downward gaze position should be considered more comfortable for both innervational and anatomical factors, as stated in previous studies of ocular mobility. A reduction of vertical saccades could also play a role in lessening visual fatigue in this gaze position.
挑选了一组VDU操作人员进行测试，以获取视觉疲劳的客观证据，并确定在特定工作环境下优先选择的显示器/注视位置。每位受试者在一个两阶段测试中被打分。当显示器相对于主要/注视位置降低时，平均得分最高；显示器处于主要或向上注视位置时获得的分数显著更低（p < 0.001）。如先前关于眼球运动的研究所表明的，从神经支配和解剖学因素来看，向下注视位置应该被认为更舒适。垂直扫视的减少也可能在减轻这个注视位置的视觉疲劳方面发挥作用。
