摘要

People have extended working hours with rapid change of social change today. Some studies find the long working hours and high use of eyes would have physical and mental conditions be in long-term fatigue and further increase the risks of emotion, sleep problems, and low work efficiency. How to improve the office workers' state is the most important issue. Therefore, we propose 12 lighting environment with different colour temperatures, illuminations and peak wavelengths of blue lights and analyse the physiological and psychological impacts for visual fatigue. In addition, Grey relational analysis is applied to analyse the correlations between physiological and psychological evaluations to control and stabilize the quality of experiment.
