摘要 研究VDT屏面亮度和文件背景照度对视觉核读作业的影响效应。以核读速度、眼肌调节辐合时间和主观舒适性为测评指标。结果上述三项指标均随VDT屏面亮度和文件背景照度的变化而发生变化。结论推荐VDT屏面亮度的合适范围为 15~ 2 0cd/m2 ,文件背景照度的合适范围为 30 0~ 45 0lux。 The effects of VDT screen luminance and file background illumination on visual proof reading performance were examined. Proof reading speed,eye accommodation and convergence time, and subjective visual comfort were employed as indexes. It was found that those indexes varied correspondingly with the changes of VDT screen luminance and file background illumination. It was concluded that the visual proof reading performances were best when the VDT screen luminance level was in the range of 15 to 20 ck/m2 and the file background illumination was in the range of 300 to 450 lux. The match between VDT screen luminance level and file background illumination were emphasized.
