Zero21

Cape Town's streets, milled into frames at The Oculus's own atelier.

The Story

Zero21 is The Oculus's in-house frame line, named after 021, the dialling code of the city it was born in. Every frame carries the name of a Cape Town street, suburb or landmark — Adderley, Bree, Kloof, Long, Whale, Higgovale, Roeland, Ocean View. Hung together, the collection reads as a map. The city is the catalogue and the streets are the line.

What sets Zero21 apart is simple and rare: The Oculus designs and mills its own frames. Almost every optical house buys frames in and puts a name on them — Zero21 is made from scratch in Cape Town. Each frame is sculpted from a solid block of Italian acetate at the De Waterkant atelier, machined on the same CNC pipeline that cuts the lens grooves and hinge pockets — a one-piece manufacturing process, start to finish, under one roof.

Because the frames are cut rather than moulded, the line thinks in two dimensions at once. A street name is the lens shape — the silhouette, bridge and proportions. A sculpting method is the cross-section, the way the front face is carved. The same Adderley keyhole aviator becomes a different object depending on how its surface is treated. These are not colour variants; they are four distinct frames that happen to share an outline.

The four sculpting methods

* Bevelicious — the front face steps down through two angled bevel planes before it reaches the lens groove. Each plane catches the light at a different angle, so the rim reads as layered rather than flat. Cut from 8mm acetate, heavy and deliberate in the hand, finished on an acetate barrel hinge with no exposed hardware. * Classic Zero21 — one continuous curved surface, no steps, tapering gently toward the viewer. The quietest of the four and the thinnest in the hand. Hung on a metal barrel hinge with two visible screws — engineering left honestly on show. * Rivages — four to five concentric channels machined horizontally across the front face, like sedimentary strata or the contour lines of a shore. Rivages is French for shores or banks. The most demanding method to machine cleanly, and the most distinctive to wear. * Convexus — the front face bows outward in a slow arc from bridge to temple. Nothing is flat. Light travels across the surface in one unbroken sweep rather than breaking at an edge.

Materials & Craft

• Italian acetate, milled in-house: Every frame is cut from a solid block on The Oculus's own CNC machines at the De Waterkant atelier — design, milling, grooving and finishing in one continuous process.
• One-piece manufacturing: The full frame shape, lens groove and hinge barrel pockets are machined as a single sculpting job, not assembled from bought-in parts.
• Four cross-section treatments: Bevelicious, Classic Zero21, Rivages and Convexus — each a different way of carving the same lens shape.
• A 72-name acetate library: Smokey Brown, Surreal, Serendipity, California Red, Antique Gold, Verde, Shocking Pink and more — the product palette every street ships in.
• Two hinge systems: Acetate barrel hinges with hidden hardware, or metal barrel hinges with the screws left visibly on show.
• Cape Town origin: Each frame is tied to the street it is named after, down to its place on the city map.

Signature Style

Zero21 is object-led and frills-free — eyewear as a sculpted thing rather than a fashion accessory. It belongs in the company it keeps at The Oculus: alongside Mykita, Kuboraum and the other houses that treat a frame as a piece of engineering. The names do the talking. A frame's identity is its street, its sculpting method, its acetate colour and its millimetres — no slogans, no story stretched over it.

The range is broad because the city is broad. Aviators, cat-eyes, hexagons and flat-tops, each named for the road it came from, each available in up to four carved cross-sections and dozens of acetate colours. The look is confident and a little playful — the same subdued, Wes-Anderson-leaning register the brand uses across its imagery — but the substance underneath is pure craft: a frame cut from a block, by the people who sell it.

Frequently Asked

What does a Zero21 frame cost?

Pricing on request — contact The Oculus for a quote. We'll walk you through frame, sculpting method and lens options before you commit.

How long until my prescription glasses are ready?

Typically 2–3 weeks from prescription to collection, depending on the lenses you choose. Because we make the frames ourselves, lead times on the frame side stay in our hands.

What's the difference between Bevelicious, Classic Zero21, Rivages and Convexus?

They're four ways of carving the same lens shape. Bevelicious steps down through bevel planes, Classic Zero21 is one smooth curve, Rivages has horizontal channels cut across the face, and Convexus bows outward. Same outline, four different objects.

Why are the frames named after streets?

Zero21 is named after Cape Town's dialling code, so every frame takes the name of a city street, suburb or landmark — Adderley, Kloof, Long, Whale and the rest. The collection is laid out as a map of the city.

Does The Oculus really make these in-house?

Yes. Each Zero21 frame is milled from a solid block of Italian acetate on our own machines at the De Waterkant atelier. Most eyewear is bought in and rebranded — we design and manufacture ours from scratch, which is unusual for an optometry studio.

What colours can I get?

Zero21 draws on a 72-name acetate library — from Smokey Brown and Antique Gold to California Red and Shocking Pink. Not every colour ships in every street; we'll show you what's available for the shape you choose.

Can I get the same shape in a different size?

Most streets come in multiple block sizes (small, medium and large proportions) and more than one bridge type. We'll fit you in person to find the right one.

Are Zero21 frames available as sunglasses?

Yes — most shapes work as both optical and sun. Speak to us about tints and lens options.

Can a Zero21 frame be repaired or remade?

Because we mill them ourselves, we can adjust, refinish and in many cases recut a frame in-house. Bring it in and we'll take a look.

Why does The Oculus put its own name on Zero21?

Because making our own frames is the thing no one else around us does. Zero21 is where our optical craft, our city and our design sense come together in one object.
