摘要： 本实验用作业效绩与眼肌调节时间变化率作指标,研究了计算机终端CRT显示的亮度对比度对视觉功能的影响。结果表明,在屏面背景亮度20cd/m~2左右时,8:1—12:1范围的对比度具有最佳的视觉功能。对比度偏离这个范围时,视觉功能水平随偏离程度而降低。4:1—18:1是CRT亮度对比的宽容度范围。

Abstract: This Experiment was carried to investigate the effects of theluminance contrast between the symbols and background of VDT. Usingaccommodation and convergence time of eyes and the performance ofreading symbols, eight luminance contrasts ranging from 3: 1 to 18: 1 werecompared. It was confirmed that when the luminance of background wasabout 20cd/m~2, the optimum contrast range was about from 8: 1 to 12: 1and the permitted luminance contrast range was from 4: 1 to 18: 1.
