A study on the relationship between visual work and color vision under LED lighting – In the case of varying the work time –

Abstract

Color vision is one of the important factors in visual work. However, there are no research reports or guidelines on visual work and color vision in LED lighting. In this research, an experiment of color sorting work under LED lighting of neutral white by varying the work time was conducted. A filter that can simulate two types of color vision (protanopia and deuteranopia) and 100 hue test was used in the experiment. From the results of color sorting experiment, it was clarified that the misjudgment of colors increased in the case of protanopia and deuteranopia compared with common type, and the judgment result did not improve even if the work time was increased. From the subjective evaluation results, it was reported by participants that it was difficult to work with protanopia and deuteranopia.
