N2 - This study examined the influence of color temperature and illuminance on visual perception. Computer-based and paper-based reading tasks were performed under various lighting conditions. Result implies that the 750 lx under 3000K color temperature condition was not recommended for office tasks due to severe glare and visual discomfort. Target illuminance for the 3000 K conditions should not exceed 500 lx to ensure visual comfort for office tasks. The 4000K color temperature functioned effectively to keep a comfortable visual environment. The 500 lx and 750 lx conditions with 4000K lamps, and the 500 lx condition with 6500K lamps effectively mitigated negative visual perception. The influential factors on visual comfort were glare, color of light, visual distraction and eye fatigue.
