Take a deeper look at the Noctura 400 Sleep Mask

  • The Noctura 400 Sleep Mask is supplied in two parts. The first being the soft cushioned fabric mask and the second being the 'pod' which contains organic light-emitting diodes (OLEDs)

  • Before you go to sleep, touch the 'on' sensor to activate the pod. The green lights will become visible and you then slide the pod into the fabric mask

  • The light therapy has been designed so that it doesn’t interfere with your sleep and each mask records patient usage
