Bvlgari BV50020I Serpenti Viper 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.

Who makes Bvlgari eyewear?
Thélios, LVMH's eyewear manufacturer, since January 2024. Luxottica held the licence from 1996 until it expired at the end of 2023. Bulgari has been part of LVMH since 2011.
What is the Serpenti collection?
The house's snake motif applied to eyewear — geometric scales along gold-finish metal temples, and an enamelled snakehead at the hinge. Serpenti and Serpenti Forever are the two main variants.
How is the range organised?
By jewellery family rather than by shape: Serpenti, Serpenti Forever, B.zero1, Bvlgari Roma, Tubogas, Divas' Dream and Calla. That is how frames are named and asked for at retail.
Is there a men's range?
Yes, though it is the smaller half. Men's styles draw on the Octo Roma and Octo Finissimo watches and use titanium for lightness.
Why have Bvlgari prices changed?
Production moved from Luxottica to Thélios in January 2024, and average retail prices rose with the change. Older listings elsewhere may still show pre-2024 pricing.
Are these frames authentic?
Yes. Bvlgari frames are sourced through authorised supply and arrive with their branded case, cloth and manufacturer documentation, with a one-year warranty against manufacturing defects.
