Which glasses suit my face?
The 2026 Expert Guide: Find the perfect frame for your face shape in 2 minutes.
Buying glasses online can be daunting: "Will they actually look good on me?"
However, optics follow simple geometric rules. Whether you are looking for stylish sunglasses for summer or your new daily
prescription glasses, the secret lies in balancing proportions.
At Visionet, we apply the golden rule of stylists: Contrast. If your face is round, add angles. If it's square, add softness. Here is how to make the right choice, every time.
1 Analyze your morphology
Don't guess. Stand in front of a well-lit mirror and tie your hair back to reveal your forehead. Observe your jawline, the width of your forehead, and your cheekbones.

2 The 5 Face Shapes
Your features are soft, with no sharp angles. The width and height of your face are almost identical.
- ✅ Do: Choose rectangular, square, or geometric shapes to "break" the roundness and refine your features.
- ❌ Don't: Avoid perfectly round glasses (John Lennon style) or small frames, which make the face look fuller.
Your jawline is strong and well-defined, your forehead is wide. You project strength and character.
- ✅ Do: Go for oval (Panto), round, or Pilot shapes to soften the angles of the jaw. Thin metal frames are ideal.
- ❌ Don't: Avoid strict square or massive shapes that harden your expression.
The "Holy Grail" of opticians. Your proportions are naturally balanced. It is the most versatile shape.
- ✅ Do: Anything! Dare to wear Oversize shapes, designer frames, or bold colors. Have fun with it.
- ❌ Don't: The only mistake is choosing a frame that is too wide for your temples, disrupting the balance.
You have a wide forehead and a narrow chin (inverted triangle). The goal is to minimize the width of the upper face.
- ✅ Do: Choose discreet frames, rimless models, or light "Cat-Eye" shapes that lift the gaze upwards.
- ❌ Don't: Avoid heavy top bars (thick acetate) that draw too much attention to the forehead.
Your face is noticeably longer than it is wide. The objective is to "cut" this verticality.
- ✅ Do: Tall frames that cover a good portion of the face (e.g., Wayfarer). A low or thick nose bridge also visually shortens the nose.
- ❌ Don't: Avoid narrow or thin rectangular glasses that emphasize length.
3 The 3 Pro Rules from Opticians
Beyond shape, visual comfort and aesthetics depend on three technical points we always check in-store:
1. The Eyebrow Line
For prescription glasses, the top of the frame should follow your eyebrow line without cutting it or covering it completely. If the eyebrow is visible inside the lens, it creates a strange expression. (Note: For Oversize sunglasses, this rule is flexible).
2. Temple Width
Glasses should not squeeze your temples. If the arms leave marks, the frame is too small. Conversely, if you can fit a finger between the arm and your temple, it's too wide. Use our size guide (pupillary distance) to check this.
3. The Smile Test (Cheekbones)
Smile widely! If your cheeks push the bottom of the frame up, the glasses will move every time you speak. This is uncomfortable and smudges the lenses. Choose models with adjustable nose pads if you have high cheekbones.
