Take a deeper look at the Noctura 400 Sleep Mask

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

  • Before you go to sleep, insert the pod into the fabric mask and activate it by gently covering the left side of the mask with the palm of your hand for up to 5 seconds. This is where the ‘On’ sensor is located, and the green lights will become visible.

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

More than just a mask

The treatment is part of an ongoing monitored therapy and regular check-ups are provided.

At the end of a 12 week period, the mask is returned for analysis and a replacement mask is provided. The collected usage data allows the clinician to compare the patient's usage of the mask with changes in vision.
