Red Tinted Sunset Lenses

Aston Sunset

Aston translates New York’s architectural edge into a bold flat-top frame with clean geometry and graphic confidence.

Geometric flat-top Medium to large fit Architectural bio-acetate

Design story

Linear, bold and city-built.

Aston is shaped around a graphic flat-top line that gives the frame immediate structure and a more directional visual identity.

The geometry feels inspired by the hard lines of the city skyline — angular where it matters, but still wearable through balanced proportion. Bio-acetate keeps the frame comfortable while allowing the silhouette to stay visually crisp.

It is a strong frame for those who prefer clarity over softness: modern, assertive and unmistakably urban.
