R01 traces a rectangular line through exposed lenses and clearly defined metal connections. A broad grooved bridge joins the two sides, echoed by matching fittings at the outer edges. Acetate temple tips introduce a change in texture, while the open construction keeps the frame’s essential junctions in view.

The stainless-steel structure has ruthenium plating, with shiny-black acetate temple tips completing the arms. Gradient grey Nylon lenses have an anti-reflective treatment on their inner surface. The lenses are 3.8 mm thick.
