What the device does.
- + Smart glasses form factor with 3 EEG sensors
- + NASA-patented neurofeedback algorithm
- + Electrochromic lenses darken when distracted, clear when focused
- + Passive training during normal tasks (reading, homework)
- + Companion app for tracking
- + No screen time required
The trade-offs.
- + **Only neurofeedback device using tinting smart glasses**
- + **Trains attention during real-world tasks** rather than in-app sessions
- + Unique form factor enables ambient neurofeedback throughout workday
- + 2015-founded Pennsylvania-based with US distribution
- − Niche use case (attention-during-work)
- − Smaller brand awareness vs Muse / Neurosity / Mendi
- − General-wellness regulatory positioning
- − Glasses form factor not for all users (eyewear-prescription compatibility issues)
ADHD, attention training, parents of kids with focus issues

Overview
Narbis is the only neurofeedback smart-glasses specialist — founded 2015 in Pennsylvania, with structural value claim fundamentally different from headband-format alternatives: Narbis uses tinting smart glasses to train attention during real-world tasks rather than dedicated app sessions. The structural mechanism: glasses tint when attention drops, providing ambient real-time neurofeedback throughout normal work activities.
For users wanting ambient neurofeedback during real-world tasks (attention training during work without dedicated session time), Narbis is structurally the only consumer-accessible option in this form factor. For users matched to traditional in-app neurofeedback sessions, headband alternatives are appropriate.
When Narbis Makes Sense
Strong fit: Real-world task attention training; ambient neurofeedback during work preference; users without dedicated session time; unique smart-glasses form factor preference.
Weaker fit: Traditional in-app session preference (Muse 2, Mendi); productivity flow-state (Neurosity Crown with on-device AI); fNIRS prefrontal training (Mendi); strongest brand awareness.
3-Year Cost of Ownership
Mid-tier consumer pricing positioning. Compare: Muse 2 ($95), Mendi ($299), Neurosity Crown ($1,499), FocusCalm (sub-$200), Emotiv Insight ($99).
Verdict: Recommended
Narbis earns a recommended verdict on its category-unique neurofeedback smart-glasses positioning (only consumer device with this form factor), trains attention during real-world tasks rather than in-app sessions, ambient neurofeedback enabling integration throughout workday, and 2015-founded Pennsylvania-based US distribution — balanced against niche use case (attention-during-work), smaller brand awareness, general-wellness regulatory positioning, and glasses form factor compatibility issues for eyewear-prescription users.
For real-world task attention training with ambient neurofeedback during work, structurally the unique consumer choice. For traditional session-based neurofeedback, alternatives are better matched.
