Exploded view of the TriEye mirror lens stack: high-definition lens, polarizing film, anti-reflective coating, anti-fog mesh, and precision mounting housing
The optical stack

Five layers. One clear view.

Every layer earns its place. Tap to see what each one does.

  1. 1 High-definition lens

    Curved impact-resistant lens engineered for optical clarity edge-to-edge. The mirror surface is integrated here — not glued on top — so what you see in the mirror is as sharp as what you see through the lens.

  2. 2 Polarizing film

    Cuts horizontal glare from wet roads, sun on water, and oncoming car windscreens. Without it, the mirror would wash out in bright conditions exactly when you need it most.

  3. 3 Anti-reflective coating

    Suppresses internal reflections that would otherwise bounce around the inside of the lens and create ghosted images in the mirror. The reason the rear view stays crisp.

  4. 4 Anti-fog mesh

    Manages the temperature gradient between your face and the outside air. Why the mirror doesn't fog when you push hard up a climb in cold conditions.

  5. 5 Precision mounting housing

    The mechanical interface that holds the mirror at exactly the right angle — and keeps it there through years of vibration, sweat, and 60 km/h descents.

From the founder

I started TriEye after one too many close calls on the road — that moment when you realize a head-check just took your eyes off where you were going. The first prototype was crude. The second was worse. We're hundreds of iterations in, and the lesson is the same every time: the mirror has to be sharp in every condition a rider will actually meet, or it isn't worth wearing.

— Jonas Nyrén, founder & optical engineer
