Abstract

To investigate the relationship between refresh frequency and human visual comfort in lighting, an experiment was designed based on subjective emotion and physiological parameters. The impact of three monochromatic light (red 623 nm, green 537 nm, and blue 445 nm) and two different white lighting (3000 K, 6500 K) were also examined. According to experimental results, each lighting has a frequency that is most comfortable in the situation of non-static light. Although both dynamic and static light have an effect on human physiological parameters, it is clear that dynamic light causes more significant changes. A physiological analysis found that lower light flicker frequencies and red/blue flicker had the greatest effect on visual acuity, and that changes were greater in myopic than orthoptic eyes. The findings demonstrate that the refresh frequency of lighting has impacts on physiological parameters as well as subjective emotions.
