  • By using sensors that replicate the photoreceptors in the eyes, the LYS wearable and app measure your surrounding light and direct you to the right light at the right time of the day.
  • Different types of light naturally affect your body: bright blue light stimulates energy and boosts concentration. Warm dim hues prompt the production of melatonin, preparing you for restorative sleep.
  • Working together, the LYS wearable and app make sure your urban lifestyle will not get in the way of your sleep-wake cycle.
  • Trial data showed that using the wearable and app for three weeks decreased the time to fall asleep by 40% and tripled users' perceived energy levels during the day.
  • LYS empowered users to make small changes in their daily routine that had significant impact on their wellbeing. From crossing to the sunny side of the street, to eating lunch by the window or shifting the angle of their work desk, LYS helped users make lasting improvements.
  • With miniature sensors that replicate the photoreceptors inside your eyes, the LYS wearable knows exactly what type of light your eyes are receiving in real-time.
