Masked 40 Hz Light

NSS is a non-invasive medical device designed for neurostimulation and brainwave entrainment.


Optoceutics has devised a unique, patent-protected method to stimulate the human visual receptors and processing cortex through alternating white lights of different wave lengths, which neutralizes the visible flicker from normal stroboscopic 40 Hz light, without losing the stimulating effect on the brain.



Our light flickers with mixed colours, such that the flashing becomes undetectable to the eye while still retaining the intended stimulus in the brain.


We use eye tracking data to measure, evaluate, and give you feedback on usage. This technology allows for unique insights into your behaviors and progress.


The lamps have a unique, functional and timeless design. All manufactured and designed in Denmark.
