Based on medical-biological research over the past 20 years, it has been found that low-intensity blue light, presented at the right time and with the right duration, has an energy-stimulating effect and can regulate the sleep-wake rhythm.

Light therapy glasses, using this medical-biological research and currently successful in a study testing 163 active-duty police officers during the night shift in the Central Netherlands, showed that:

  • Police officers sleep quality improved after two months of using the light therapy glasses
  • Police officers in the study would recommend using the light therapy glasses to colleagues
  • Police officers wanted use the glasses more often
  • The light therapy glasses were used frequently indoors
