PROPEAQ 3 light glasses

The PROPEAQ light therapy glasses deliver a powerful dose of blue light that mimics natural daylight. This stimulates alertness and concentration, giving you an energetic start to the day.

  • Integrated LEDs provide an optimal intensity of 250 M-EDI (≈ 10,000 lux).
  • Just 30 minutes a day is often enough. The glasses switch off automatically after 30 minutes, no need to keep track of the time yourself.
  • With a rechargeable battery offering 3 hours of use, you’ll have enough power for around six sessions.
  • One press of the button starts your light session. Hold the button slightly longer to check the battery status.

In short: simple to use, powerful in effect.
