The light is the feedback.
Lenses tint and clear so trainings happen in real life — not on a screen.

Narbis Edge electrochromic lenses work as a universal feedback display for clinical EEG, Muse S Athena, Muse 2, and any 10–20 site. They support EEG, fNIRS, HRV, GSR, and EMG feedback.
4-channel dry EEG with Aux input for neurofeedback trainings.
Supported
EEG + fNIRS for multi-modal brain-activity insight.
Supported · fNIRS
Connect clinical EEG systems and any 10–20 site for screen-free feedback.
Clinical integrationPair your EEG device with Narbis Edge and the app translates brain activity into lens feedback in real time.
Connect your Muse 2 or Muse S (Athena) to the Narbis companion app via Bluetooth.
The app reads brain activity and converts focus metrics into real-time lens-tint commands.
Focused? Lenses stay clear. Attention drifts? They gently tint. No screen needed — feedback lives in your peripheral vision.
Edge lenses can display any physiology that can be measured. One device, unlimited modalities.

Neurofeedback uses operant conditioning to train attention, focus, and relaxation. When you're distracted, the lenses tint. When you're focused, they clear. Your brain learns to sustain the clear state.
Narbis glasses are training tools, not medical devices. For those with medical conditions, use under professional supervision.
