Influences of visual fatigue on the productivity of subjects using visual display terminals in a light-emitting diode lighting environment
With international trends of energy saving and low emissions, pursuing healthy and low-emission buildings as well as ensuring the quality of interior environments have become critical issues in the 21st century. By means of applying critical flicker frequency to the quantitative assessment of objective visual fatigue, and using a visual fatigue questionnaire to evaluate subjective visual fatigue, this study attempts, in 500lux and 200lux lighting environments, to investigate the influence of visual fatigue on working performance when using visual display terminals. Changes in productivity as a result of subjective and objective visual fatigue under different artificial lights have been analysed. The outcome shows that with light-emitting diode lighting, the sense of alertness and productivity was better. In terms of productivity, the 200lux lighting environment was even better than the 500lux lighting standard for a general operation environment, as suggested by the Illumination Engineering Society.
