The research also showed improvements in subjective measures of positive moods, work performance, fatigue in the evening, irritability, ability to concentrate and focus and eye strain. The workers also reported improved sleep at night.
The blue-enriched white light is thought to be more effective because it targets a recently discovered novel photoreceptor in the eye. (more…)
