Inside the Clarish™ Range: Ten Acetate Shapes and How They Fit

A model-by-model guide to the ten Clarish™ cellulose acetate optical frames in current production — sizes, shapes, bridge widths and how to assemble them into a retail range.

RTC Eyewear8 min read

Ten models is a small catalogue by the standards of a large factory, and deliberately so. Each one exists to cover a specific position on the sizing curve rather than to pad a page. This is what each does, and how they fit together into a range a retailer can actually sell.

Every size below is read off the temple of the photographed frame, in the standard order: lens width bridge width – temple length, all in millimetres.

The full range at a glance

Model Shape Size Colourways
C.1102 Rectangle 5618 – 145 12
C.1233 Square 5519 – 145 10
C.1262 Round 4919 – 135 12
C.1271 Rectangle 5617 – 145 12
C.213 Rectangle 5518 – 140 12
C.215 Rectangle 5317 – 140 12
C.243 Rectangle 5518 – 140 12
C.245 Soft rectangle 5218 – 140 12
C.319 Square 5421 – 145 10
C.356 Rectangle 5217 – 140 12

Read that table as a sizing curve and the logic appears. Lens widths run from 49mm to 56mm, bridges from 17mm to 21mm, temples from 135mm to 145mm. That spread is what lets one supplier cover a whole market rather than one face shape.

The wide fits: C.1102 and C.1271

Both are 56mm rectangles on 145mm temples, and at first glance they look interchangeable. The difference is the bridge.

C.1102 runs an 18mm bridge. C.1271 drops to 17mm. One millimetre sounds trivial until you fit it: the narrower bridge pulls the lenses closer together, which suits a narrower nose without giving up any lens area. So you can offer the same broad, level front to two different nose widths.

If you are stocking one of them, take C.1102 — 18mm is the more common bridge. If you are stocking a proper range, take both, because the customer who cannot wear one will usually wear the other.

The everyday middle: C.213, C.243 and C.245

C.213 at 5518 – 140 is the most broadly wearable shape we make. Nothing about it is extreme, which is exactly why it tends to be the volume model in an assortment.

C.243 matches it on paper — also 5518 – 140 — but the rim is worked to a softer profile through the lower edge. Same fit, different character. That is a useful pairing: a customer who likes the size but finds C.213 too severe has somewhere to go without being re-measured.

C.245 rounds the corners into a softer, more oval silhouette on a smaller 52mm front. It is the least severe shape in the range and flatters the widest spread of face shapes, which makes it a sensible first model for a new own-brand line.

The narrow fits: C.215 and C.356

C.215 (5317 – 140) and C.356 (5217 – 140) are the small end. Both bring the eye and the bridge down together rather than simply shortening the front — the difference a wearer notices between a frame that is scaled properly and one that has been trimmed.

C.356 is the most compact rectangle we run. Paired with C.1102 at the other end, the two of them bracket the entire rectangular range.

The statement shapes: C.1233 and C.319

C.1233 is an oversized square on a 55mm eye with a heavy browline and a 19mm bridge. C.319 goes further: a 54mm squared eye on a 21mm bridge, the widest we produce.

That 21mm figure is unusual and deliberate. Oversized frames typically fail at fit — a large lens drops onto the cheek. A wider bridge holds the front higher on the face, which is what makes the size wearable rather than merely fashionable. If your market wants bold shapes, C.319 is the one that will come back with fewer complaints.

Both run 10 colourways rather than 12, so plan assortments accordingly.

The compact round: C.1262

C.1262 is the only true round in the range and the smallest frame overall at 4919 – 135. Note the temple: 135mm, shorter than anything else here. That is a genuinely compact fit, not an adult frame scaled down.

The rim is kept slim so the shape stays light, and the bridge is keyhole-influenced, sitting on the sides of the nose rather than across it. Round shapes live or die on that detail.

How to build a range from ten models

A workable starting assortment, if you are launching rather than replenishing:

  • Two everyday rectangles — C.213 and C.245. These carry the volume.
  • One wide fit — C.1102, for the customers the mid-size frames do not reach.
  • One narrow fit — C.356, for the same reason at the other end.
  • One statement — C.319 if your market is fashion-led, C.1233 if it is more conservative.
  • One round — C.1262, which sells to a customer the rectangles will never reach.

Six models covering 49mm to 56mm. Add C.1271, C.215 and C.243 as the range proves itself, since each one deepens a fit you already stock rather than opening a new one.

What is not on this page

Frame weight, hinge type and lens fitting are not published per model, because they depend on the sheet and components specified for a given run. Colourway counts describe what was photographed, not a ceiling — sheet is selected per programme, and a colour that is not in stock can usually be sourced, which affects lead time.

If a shape here is close to what you want but not exact, that is normal and fixable. Sizing, rim profile and colour can all be adapted, which is where ODM development starts.
