How Should Sunglasses Fit? A Guide to Finding the Right Size
A good pair of sunglasses should stay comfortably in place without pinching your temples, pressing heavily on your nose, or sliding every time you look down.
The right fit matters for more than appearance. Sunglasses that fit properly are easier to wear while driving, boating, fishing, traveling, or spending a long afternoon outside. Here is how to tell whether your sunglasses actually fit.
Start With the Frame Width
The front of the frame should be close to the width of your face. It can extend slightly beyond your temples, but it should not look dramatically wider than your head.
If the frame is too wide, your sunglasses may feel loose and slide whenever you turn your head. If it is too narrow, the arms may press against your temples and become uncomfortable after an hour or two.
Look straight into a mirror. The frame should appear balanced across your face, and your eyes should sit reasonably close to the center of each lens.
Check How the Bridge Sits on Your Nose
The bridge is the part of the frame that rests on your nose. It should make comfortable, even contact without creating a painful pressure point.
A bridge that is too wide can cause sunglasses to continually slide down. A bridge that is too narrow may sit too high or leave noticeable marks on your nose.
Some movement during a hot Texas afternoon is normal, especially when sunscreen and sweat are involved. Constant slipping during normal activity usually means the bridge or overall frame is not the right size.
Make Sure the Arms Are Comfortable
The arms should follow the sides of your head without squeezing. They should feel secure around your ears, but you should not have to force them open when putting the sunglasses on.
Signs that the arms may be too tight include:
- Pressure at your temples
- Deep marks along the sides of your head
- Discomfort behind your ears
- A frame that feels stretched when worn
If the arms flare noticeably outward, the frame may be too narrow. If they barely touch the sides of your head, the frame may be too wide.
Check Your Cheeks and Eyelashes
The bottom of the frame should not press heavily into your cheeks when your face is relaxed. A little contact when you smile can happen with larger frames, but the sunglasses should not lift every time you move your cheeks.
Your eyelashes also should not continually brush the lenses. That can leave oil on the lens and become distracting throughout the day.
Try the Movement Test
Once the sunglasses feel comfortable, look down and gently shake your head from side to side. You do not need to recreate a roller coaster. You are simply checking whether the frame stays in its normal position.
Properly fitted sunglasses should remain secure during ordinary movement. That becomes especially important when you are walking near the water, loading a boat, fishing, hiking, or moving around outside.
Several LAKE styles feature a non slip fit designed for active sunny days. The Austin Black polarized sunglasses, for example, combine a lightweight everyday frame with a non slip design.
How to Tell if Sunglasses Are Too Big
Your sunglasses may be too large if they:
- Slide down your nose repeatedly
- Fall forward when you look down
- Extend far beyond the sides of your face
- Sit unevenly or unusually low
- Leave your eyes far from the center of the lenses
An oversized style can still fit correctly. The important difference is that a deliberately large frame remains secure, while a poorly fitted frame moves constantly.
How to Tell if Sunglasses Are Too Small
Your sunglasses may be too small if they:
- Squeeze your temples
- Leave deep pressure marks
- Feel difficult to remove
- Sit unusually high on your nose
- Have arms that bow outward around your head
Persistent pressure is not something you should have to tolerate. A different frame size or shape will usually feel better.
Fit and Face Shape Are Not the Same Thing
Face shape helps you choose a flattering style. Fit determines whether that style is comfortable and secure.
A frame can look great with your face shape and still be the wrong physical size. Start with comfort and stability, then consider shape and color. Our guide to choosing sunglasses for your face shape can help with the style side of the decision.
LAKE offers several frame profiles. The Powell is listed as a good option for medium face shapes, while the larger Travis rectangle frame is intended for medium to larger faces. You can compare both with the rest of the LAKE polarized sunglasses collection.
The Final Fit Check
The best sunglasses are the pair you forget you are wearing. They should feel secure without squeezing, remain balanced on your nose, and stay comfortable throughout the day.
Before choosing a color or lens style, spend a moment checking the bridge, frame width, arms, and overall stability. A proper fit means less adjusting and more time enjoying wherever the day takes you.
