摘要： 本实验研究了VDT不同屏面亮度与对比度对视疲劳的影响。实验中采用远近视点的眼肌调节时间变化率作指标,对VDT作业的不同时段进行视疲劳测定。屏面亮度取20、30、40Cd/m~2三种水平,对比度取3:1至15:1,分成七等。实验结果表明,在本实验所取的屏面亮度范围内:(1)9:1～11:1对比度所引起的视疲劳最轻,对比度愈趋近高低两端所引起的视疲劳愈深;(2)不同水平的屏面亮度对视疲劳有不同程度的影响。对比度小于7:1时,高亮屏所引起的视疲劳程度比低亮屏的轻;对比度大于7:1时,高亮屏比低亮屏更易引起疲劳。

Abstract: This paper is the experimental results of our study on the relation- ship between the luminance contrast of a VDT and visual fatigue. The accommodation and convergence time of the subjects' eyes were used as an evaluation oriterion in our experiment. The screen luminance was 20, 30 and 40 cd/m~2. The range of contrst was from 3 : 1 to 15 : 1. The results were as follows: (1) The visual fatigue was not serious within the range of luminan- ce contrast from 9 : 1 to 11 : 1; The more contrast levels deviated from the range, the more the degree of visual fatigue became greater. (2) The level of screen luminance significantly affects visual fati- gue. When the contrast was under 7:1, the visual fatigue caused by high level lunminace had less than that caused by low level luminance. When the contrast was above 7:1, the visual fatigue caused by high level lun- minace was more serious than that caused by low level luminance.
