不同距离反射眩光对视觉判读作业绩效的影响

Effects of Reflectance Glare in Different Distance on Visual Task Performance

该研究在控制眩光亮度和面积的条件下，使用正确率、反应时作指标，研究了不同距离反射眩光对视觉判断作业绩效的影响。实验结果证明：当视标亮度为１．５ｃｄ／ｍ２，反射眩光的亮度为２．０ｃｄ／ｍ２时，反射眩光对被试的视觉作业绩效有一定影响，而且反射眩光离判读者越近，视觉作业绩效越差，但这种效应不太显著。

An experiment was conducted to investigate the effects of reflectance glare in different distances on the visual performance.The indenpendent variable was the distance of glare ranging from 5cm to 15cm.The luminance of visual task is 1.5 cd/m 2. RT and correct Rate were analysed.The results showed that the visual performance got worst when the distance of glare changed from 15cm to 5cm. The distance of glare was one of the important factors affecting the visual performance.
