Carrera C FLEX 04/G Rectangle Eyeglasses
On orders over Dhs 500
Most of our frames are “one size,” designed to fit a wide range of faces. A few styles come in multiple sizes. Use your current glasses as the best reference, or follow the quick steps below.
1) How to read frame size (on your glasses)
Look inside the temple (arm). You’ll see numbers like: 52□18–140
-
52 = Lens width (mm)
-
18 = Bridge width (mm)
-
140 = Temple length (mm)
Match these to the new frame for the most reliable fit.
2) Quick fit by face width (no glasses handy?)
Use a ruler (millimeters) across your face at the pupils, or try the “credit-card test” (a card is ~54 mm wide).
| Face width | Typical lens width | Typical bridge | Temple length |
|---|---|---|---|
| Narrow | 48–51 mm | 15–18 mm | 135–140 mm |
| Medium | 52–54 mm | 16–19 mm | 140–145 mm |
| Wide | 55–57 mm | 17–21 mm | 145–150 mm |
Tip: Sunglasses often run 1–2 mm larger than optical frames for a comfortable, slightly looser fit.
3) One-size frames—how to choose
-
Compare the listed size to your current frame stamp (e.g., if you wear 52□18–140, look for something close: 51–53 lens, 17–19 bridge, 140–145 temple).
-
If between sizes, pick slightly larger for sunglasses and closer match for optical.
-
Small adjustments (nose pads, temple bend) by an optician can fine-tune the fit.
4) What each number changes
-
Lens width: overall frame width/coverage.
-
Bridge: comfort on the nose; higher bridge = more space.
-
Temple length: behind-ear comfort; longer temples for larger heads or if temples feel tight/short.
5) Common size examples
-
Optical (unisex): 50–54 / 17–19 / 140–145
-
Sunglasses (unisex): 52–56 / 16–20 / 140–150
-
Smaller faces: start at lens width 48–50
-
Larger faces: look at 55–57
6) Still unsure?
-
Match your current frame numbers first.
-
Check our product photos on model notes (if available).
-
You can message us your current size (e.g., 52□18–140) and preferred fit (snug/standard/relaxed)—we’ll suggest options.
Carrera
Motorsport, in Optyl
Founded in Austria in 1956 by Wilhelm Anger and named after the Carrera Panamericana road race. Unlike the fashion houses, Carrera began as an eyewear company, and Optyl — Anger's 1964 patent — is still its defining material.

What is Optyl?
A heat-cured plastic that Carrera's founder Wilhelm Anger patented in 1964. It is around 20% lighter than acetate and returns to its moulded shape through a memory effect. It is still used in Carrera's heritage-revival frames.
Who owns Carrera?
Safilo Group, which acquired the brand in 1996. Carrera is a Safilo house brand rather than a licensed fashion name, and the headquarters moved to Padova, Italy after the acquisition.
Where does the name come from?
The Carrera Panamericana, the Mexican road race. The brand was founded in Austria in 1956 as a sports and performance eyewear maker.
Which Carrera models are the heritage ones?
Champion, Endurance, Safari and Panamerika, reissued as the Icons line for the brand's 65th anniversary and sold as CHAMPION65, ENDURANCE65, SAFARI65 and PANAMERIKA65. They are remasters of 1980s originals.
What is Carrera Ducati?
A motorsport line using carbon fibre and titanium with wraparound fronts and straight temples. The partnership is confirmed to run to 2029.
Are these frames authentic?
Yes. Carrera frames are sourced through authorised supply and arrive with their case, cloth and manufacturer documentation, with a one-year warranty against manufacturing defects.
