Generally, visual distance is set on 40cm to 80cm on the VDT (Visual Display Terminal) work. Visual distance must be selected with required terms. On this paper, three type visual distances which were 35,55,75cm were set on experimental booth and physiological load was evaluated on each visual distance. As a result, stimulus of great light acted acceleration system and awakening level was held highly till 20 minutes. However, stimulus of great light led fatigue presently and acted break system. Furthermore, awakening level was fell and working accuracy was dropped. While on 75cm visual distance, stimulus of poor light acted break system and awakening level was sank immediately after the start of the work and dropped working accuracy. Against afforesaid two visual distances, stimulus of moderate light acted acceleration system moderately and fatigue did not appear on 55cm visual distance. Then it was cleared this visual distance kept high awakening level and was able to offer hith working accuracy on 1 hour VDT work.
