The ingenuity of the Vettron is apparent in its unique aesthetic and unexpected functionality. Optic Nerve started with a retro-forward design and updated the geometry to sync with today's trends. They then added innovative mechanics including a Gate Hinge system which allows the user to lift and unfold half of the frame to release the lens from the frame channel. The result not only nails the rapidly growing trail to tavern philosophy but pushes well beyond it.
