Miu Miu MU 51XV Square 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.
Miu Miu
The second house of Prada
Miuccia Prada created Miu Miu in 1993 as Prada Group's second house — not a diffusion line, but a separate label with its own collections and creative direction. The eyewear is younger, more experimental and predominantly women's-led.

The Miu Miu MU 51XV is a full-rim square eyeglass frame for women, with a metal front and metal temples. It comes with demo lenses, so you can add single-vision, progressive, reading or non-prescription lenses when you order. It has an adjustable nosepads fit and often suits round, oval and diamond face shapes.
A square drawn in thin metal, which is an uncommon combination — it gives the frame the angularity of acetate with almost none of the mass. The MU 51XV runs 54mm on a 17mm bridge with a 135mm arm, shorter than nearly everything else in the optical range, and that combination of wide front, narrow bridge and short temple makes it a specific fit rather than a general one. It is made in one size only, with nothing to fall back on. Gold. Try these eyeglasses before ordering: when they suit you they suit you completely, and when they do not there is no second option.

Is Miu Miu the same as Prada?
No. Miu Miu is Prada Group's second house, created by Miuccia Prada in 1993 and run as a separate label with its own collections and creative direction — not a diffusion version of Prada.
Who makes Miu Miu eyewear?
EssilorLuxottica, under the Prada Group licence that also covers Prada and Prada Linea Rossa. The agreement now runs to the end of 2030 with an option to 2035.
What are the main Miu Miu eyewear lines?
Runway is the recurring core of the range. Glimpse, Regard and Vedette sit alongside it. Frames also carry MU reference codes inside the temple.
How does Miu Miu eyewear differ from Prada's?
It is more experimental and more decorative — strongly drawn oversized or narrow-rectangular fronts with glitter, crystal and coloured acetate treatments, and it skews younger and more women's-led.
Can Miu Miu sunglasses be glazed to prescription?
Most can, and Miu Miu produces a full optical range separately. Shield and mask shapes restrict the prescription range — our opticians will confirm the frame before ordering.
Are these frames authentic?
Yes. Miu Miu frames are sourced through authorised supply and arrive with their branded case, cloth and manufacturer documentation, with a one-year warranty against manufacturing defects.
