Have you ever ordered a pair of glasses you fell in love with online, tried them on excitedly when they arrived, and felt hugely disappointed when you looked in the mirror? You're not alone.
It's not you, and it's not the glasses either. It's a question of geometry. At Mister Lunettes, we consider optics to be facial architecture. The right frame can enhance your cheekbones, refine your features, and make you look more serious or, conversely, more approachable.
In this comprehensive reference guide (updated for 2025), we'll deconstruct the science of "visagism" together. Get ready to never make a mistake again.

1. The foolproof method for determining your body shape
Many people think they have a "round" face when it is oval, or "square" when it is rectangular. To find out for sure, forget about guesswork. Take the technical test.
The Mirror and Lipstick Test
This is the technique used by professional makeup artists. Here's how to do it:
- Stand in front of a mirror in a well-lit room.
- Tie your hair back or pull it back to completely clear your forehead and ears.
- Keep a neutral expression (do not smile).
- Using lipstick, an erasable marker, or a piece of dry soap, literally trace the outline of your face on the mirror.
- Take a step back and observe the shape you have drawn.
Not sure if your face is "wide" or "narrow"? Take a standard credit card. Place it vertically in the center of your nose.
- If the card reaches the outer edges of your eyes: You have a narrow/medium face.
- If your eyes extend well beyond the card: You have a wide face.
2. Round Face: Focus on Structure
Morphological analysis:
Your face has no prominent angles. The width at the cheekbones is roughly equal to the length of the face. Your cheeks are full and your chin is rounded. It is a face that inspires gentleness, youthfulness, and friendliness.
The optical strategy
You need to add what's missing: angles and length. The goal is to visually stretch the face upward and slim down the cheeks.
✅ What to prioritize:
- Rectangular shapes: They break up the roundness and give structure to the face.
- Geometric frames: Hexagonal or square, very trendy in 2025.
- Transparent or thin bridges: They visually separate the eyes.
- Dark colors: A black or dark tortoiseshell frame "tightens" the features.
❌ What to avoid:
- Round glasses (John Lennon style), unless you want to accentuate the "doll" effect.
- Frames that are too small make the face appear larger by contrast.
3. The Square Face: The Art of Contrast
Morphological analysis:
You have a "movie star face." Your forehead is broad, and your jaw is as wide as your cheekbones. The angles of your jaw are well defined, almost at 90 degrees. It is a face that exudes power and character.
The optical strategy
There are two schools to choose from, depending on your personality:
Option A: Soften features (Recommended)
To make the face appear less severe, curves are used. Round, oval, or "Pantos" style glasses are ideal. Thin metal frames (gold or silver) work wonderfully to add elegance without weighing down the look.
Option B: Embrace power
If you want a distinctly intellectual or very fashionable look, you can opt for thick square glasses. Be careful, though, as this can make your gaze appear much harsher.

Morphological analysis:
This is the "Golden Ticket" of eyewear. Your face is naturally proportioned. It is slightly longer than it is wide, the forehead is neither too wide nor too narrow, and the jawline is rounded.
Anything goes (or almost anything)
Your body shape allows you to be bold with all kinds of eccentricities. Now is the time to experiment:
- Oversized glasses (very large).
- Bold butterfly shapes.
- Bright colors such as Mister Lunettes' signature orange.
The only rule to follow: The width of the frame. Your glasses should be as wide (or slightly wider) as the widest part of your face. If they are narrower, your face will appear unnecessarily elongated.
5. The Triangular (or Heart-Shaped) Face
Morphological analysis:
Often referred to as a heart-shaped or inverted triangle face. Your forehead is wide, your cheekbones are high, and your face tapers to a pointed or narrow chin.
The strategy: Rebalancing the bottom
Since the upper part of the face is wide, you should avoid adding too much visual weight to it. The aim is to draw the eye downwards.
The best choices:
- Perforated or invisible frames: They are barely noticeable on the forehead.
- Elongated shapes (cat-eye): These follow the natural line of your cheekbones.
- Light or pastel colors: To soften the upper part of the face.
6. Technique: How to choose the right size?
Beyond shape, size is crucial for comfort. Have you ever noticed small numbers written inside the arms of your glasses (e.g., 50▢20 140)? Here's how to read them so you can order online like a pro.
1. The Caliber (e.g., 50)
This is the width of a lens in millimeters.
Small face: 47-50mm
Medium face: 51-54mm
Large face: 55mm and above
2. The Bridge (e.g., 20)
This is the width at the nose.
Narrow nose: 16-18mm
Standard nose: 19-21mm
Wide nose: 22mm and above
Note: At Mister Lunettes, we indicate these measurements on each product page to ensure your satisfaction.
7. Trend 2025: The Connected Revolution
No matter your body type, one pair of glasses is redefining the rules of fashion and technology: Ray-Ban Meta.
Why are we talking about this in a style guide? Because Ray-Ban had the foresight to use its iconic Wayfarer frame. Created in the 1950s, the Wayfarer is known for being the only frame that suits (literally) everyone. Its trapezoidal shape suits round, oval, and square faces.
Why choose Ray-Ban Meta?
- 📸 Capture the moment: 12 MP ultra-wide camera built into the frame.
- 🎵 Immersive sound: Listen to your music without headphones thanks to directional speakers.
- 🤖 Built-in AI: Make calls and send messages using your voice.
- 🕶️ Timeless Style: No one will guess that you're wearing a computer on your nose.

8. Frequently Asked Questions (FAQ)
Here are the answers to the questions our customers ask us most often before making a purchase.
What color glasses should I choose if I have blue eyes?
To bring out the blue in your eyes, play with contrast or complementary colors. Orange, brown tortoiseshell, or copper frames are best because orange is the opposite color of blue. Steel gray or silver also works very well for a tone-on-tone look.
Should my glasses hide my eyebrows?
Absolutely not! That's the golden rule. The top line of the frame should follow the line of your eyebrows or sit just below them. If your eyebrows are invisible behind the lenses, you lose all your facial expression. The only exception is oversized sunglasses for women.
How can you tell if your glasses are too big?
If you can fit more than one finger between the arm and your temple, they are too wide. If they slide down your nose when you lower your head, the bridge is too wide. If they touch your cheeks when you smile, the lenses are too high.
Can I get a refund for my glasses purchased from Mister Lunettes?
Yes, we accept returns. In addition, our glasses may be eligible for reimbursement by your health insurance provider, depending on your policy. We provide a detailed invoice in accordance with regulations.
