Miu Miu MU B09S Oval Sunglasses
On orders over Dhs 500
Offer ends in
The raised upper rim is the detail — it lifts away from the lens line like a spoiler, and it is what separates the MU B09S from the plainer shapes around it. All acetate, 52mm on a 21mm bridge with a 140mm arm, which makes it stable enough for daily wear rather than occasion wear. Black only, with a solid tint rather than a gradient. The manufacturer states the lenses block 100% of UVA and UVB rays for this reference, which is confirmed here and deliberately not assumed elsewhere. One recognisable Miu Miu gesture on an otherwise simple oval.
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 B09S is a full-rim oval sunglass for women, with an acetate front, acetate temples and nylon lenses. It has a high bridge fit and often suits square, diamond and oblong face shapes.
The raised upper rim is the detail — it lifts away from the lens line like a spoiler, and it is what separates the MU B09S from the plainer shapes around it. All acetate, 52mm on a 21mm bridge with a 140mm arm, which makes it stable enough for daily wear rather than occasion wear. Black only, with a solid tint rather than a gradient. The manufacturer states the lenses block 100% of UVA and UVB rays for this reference, which is confirmed here and deliberately not assumed elsewhere.
