红光照明条件下VDT不同显示色的视觉效果比较

本研究以VDT上持续进行的视觉作业速度和眼的调节辐合时间作为指标,对红光照明条件下VDT显示的红、黄、绿、蓝、白五种字符色的视觉效果进行了比较.实验中,VDT背景光的主波长为630nm.结果表明,五种字符色在两项指标上均表现出显著差异;绿色显示的视觉效果最好,红色显示的效果最差,黄、白、蓝三色处于中间.

A Comparison of the Visual Effectiveness of Different Display Colors at a VDT Under the Condition of Red Illumination

With the speed of visual work at a VDT and the accommodation and convergence time of the eye as indicators, a comparison was made of the effectiveness of different colors of characters at a VDT under the condition of red illumination Five colors were chosen for VDT display: red, yellow, green, blue and white It was found that green was the best in terms of both visual performance and fatigue effect and that red was consistently the worst, with yellow, white and blue falling in between
