Subjective experiment was conducted to identify the difference in visibility of the target with different wavelength at peripheral vision and the effects on visibility of luminance level and luminous colour to which the subjects adapted.As results, all subjects could perceive and judge the colour of the target exposed at the centre of the visual field under every experimental conditions. No significant effects of the change in luminance or luminous colour to which the subjects adapted were found on the visibility level of luminous colour at central vision. In the case when the eccentric angle of the target from the subjects' vision became larger than 40 degree, the percentage of the subjects who could judge the colour of the target correctly decreased dramatically. It also could be seen that the percentage of the young subjects who could judge the luminous colour of blue was higher than that of green in the case when they evaluated under the conditions of 2 lx.

通过主观实验研究了不同波长的目标物在周边视觉上的可见性差异，以及被试所适应的亮度水平和发光颜色对可见性的影响，结果表明，在各种实验条件下，所有被试都能感知和判断暴露在视野中心的目标物的颜色。没有显着的影响，在亮度或发光颜色的主题适应的变化被发现在中央视觉的发光颜色的可见度水平。当目标与被试视觉的偏心角大于40度时，被试能正确判断目标颜色的百分比显著下降。还可以看出，在2 lx条件下进行评价时，年轻受试者能够判断蓝色发光颜色的百分比高于绿色。
