目标和背景文献报导的数据显示终端操作者感受到视觉故障、经常引用的故障同观察者适应响应的关系以及工作环境中多色显象管数目的增长,都促使开展本研究工作。本研究的目的,是为了研究当观察彩色背景上呈现彩色目标时,色差对目视适应性的影响。众所周知,不同波长的字符会以不同方式聚焦在眼睛视网膜上。相对使消色目标聚焦所需的折射来讲,短波长目标可聚焦至远 Data reported by the target and background literature suggest that terminal operators perceive visual faults, the frequently cited fault-observer adaptive response, and the increase in the number of multicolor kinescopes in the work environment, all contributing to this work. The purpose of this study was to investigate the effect of color differences on visual adaptability when viewing color targets on a colored background. It is well known that characters of different wavelengths will be focused on the retina of the eye in different ways. The short wavelength target can be focused as far as the refraction required to achromatize the focus
