You stand in front of a massive wall of sunglasses at Karns Vision Center, wondering what might look amazing on you. You try on pair after pair, but nothing seems to look quite “right”. Maybe the sunglasses are sliding down your nose, resting too high on your cheeks, or making your head look strangely wide. We know what this is like, and you’re not alone.
Finding the right fit doesn’t have to feel like a guessing game. To find sunglasses that suit your face, you can start by identifying your face shape and choosing frames with contrasting angles. This is just a helpful guideline, but it can give you a sense of what might work so you have a place to start.
How to Determine Your Face Shape
Look at Your Features in a Mirror
Stand in front of a mirror and pull your hair back so that you can see the full outline of your face without any distractions. Grab a dry-erase marker to gently trace the reflection of your face on the glass.
Step back and look at the shape you drew, paying extra close attention to the width of your jaw and cheekbones. This can give you a sense of your general face shape: Is it more circular or oval? Or do you have a fairly square or diamond-shaped face? You can use this shape to guide you in what frames might complement your features.
Compare Your Facial Proportions
You can also use a tape measure to check your facial proportions. Comparing the width of your forehead, cheekbones, and jawline can help you better understand your facial proportions. This information can be a helpful starting point when you go to try on frames.

Sunglasses for Round and Oval Faces
Shapes for a Round Face
A round face usually features full cheeks and a rounded chin, and the width and length of your face measure about the same. People with this face shape often want to add some contrast to their soft features.
You can achieve this contrast by choosing angular frames. Geometric styles and rectangular glasses add sharp lines to your soft facial curves. You may want to avoid small circular frames because they can make your face look rounder.
Shapes for an Oval Face
An oval face is longer than it is wide, with high cheekbones and a tapered chin. This balanced proportion makes oval faces versatile.
Most frame styles look nice on an oval face. You have the freedom to play with any shape that you’re comfortable with.
Sunglasses for Square and Heart Faces
Frames for a Square Face
A square face has a strong, defined jawline. Your forehead, cheekbones, and jaw are all of similar width. Some people with square features look to balance them by adding curved frames.
You can try round or oval glasses from various frame and lens options to balance your prominent jaw. Dark thin frames can also help draw attention up toward your eyes.
Frames for a Heart Face
A heart face has a wide forehead and a narrow chin. Your cheekbones often look high and prominent, and your face tapers sharply from the top down to the bottom.
Frames that are slightly wider than your forehead can help balance these proportions. Bottom-heavy styles can also help broaden the look of your chin, and light colors keep the glasses from overpowering your delicate facial features.
Frames for a Diamond Face
A diamond face features full cheekbones and a narrow forehead, which creates that distinctive diamond look. You want glasses that complement these high points without hiding them, while still providing effective UV protection.
Frames with heavy tops often work well for a diamond face. They add weight to your narrow forehead while balancing your striking cheekbones. Try cat eye or oval sunglasses to soften your sharp features. Gentle curves can also highlight your eyes beautifully.
Tips for a Comfortable Fit
Check Frame Width and Proportions
Your new sunglasses should fit your face comfortably. They shouldn’t rest on your cheeks when you put them on, and your eyes should sit near the center of each lens, especially if they are prescription.
Our opticians can adjust your frames so that they are custom-fitted to your face. A professional fitting keeps your sunglasses from sliding down your nose or pinching your ears. Regardless of frame shape, look for lenses that provide 100% UVA and UVB protection.
