VDT不同颜色显示的视觉工效比较

A Comparison of Visual Performance with VDT Using Differently Colored Characters

本项研究采用视觉作业速度、眼肌调节辐合时间变化和主观评价三项指标,对VDT显示的白、绿、蓝、黄、红、紫红6种颜色的视觉工效进行了比较。在实验中三项指标得到一致的结果。绿色显示的工效最好,红色与紫红色最差,蓝、黄、白处于中间,三者间无显著差异。

In this study, speed of visual task, rate of eye muscle accommodation and convergence time, and subjective assessment were used as indicators of the visual performance in comparison of VDT seting differently colored characters. Six kinds of colors were chosen for VDT display: white, green, blue, yellow, red and purple. The results of those three indicators were consistent with each other. Green characters for the visual display on VDT was the best, whereas blue yellow and white characters were the second. There were no significant differences among them. The red and purple chara- cters were the worst in terms of visual performance.
