Persol frames are built to last decades — but even the best-made sunglasses need occasional adjustment as temples loosen and nose pads shift. A proper fit keeps the lenses positioned correctly and stops the sliding.
Here’s how to adjust them carefully without damaging the frame.
However, when you buy a new pair of Persol sunglasses, it’s important to make sure they fit properly. If they’re too loose or tight, the sunglasses won’t provide you with the protection you need. To ensure your Persol sunglasses provide you with the best possible vision, you should adjust them to fit your face. Here’s how:
First, hold your sunglasses up to your face and use the nose pads to adjust the frames so they sit comfortably on your nose. Make sure the frames are even on both sides and that the weight is evenly distributed over your nose.
Next, use the temple tips to adjust the arms so they rest behind your ears. Again, make sure the arms are even and not stretching or pulling on either side.
Finally, use the temple adjuster on the arms to adjust the length of the arms. This will ensure the arms fit securely and comfortably behind your ears.
Can Persol frames be adjusted?
It is generally possible to adjust Persol frames to better fit your face and improve comfort. Persol frames are designed to be adjustable, and most styles come with adjustable nose pads and temple tips to help you achieve a comfortable and secure fit.
To adjust Persol frames, you may need to use a small screwdriver to loosen or tighten the screws on the nose pads or temple tips. Some Persol frames also have adjustable hinges that allow you to change the angle of the frames to better fit the shape of your face.
If you are having trouble adjusting your Persol frames or you are unsure how to proceed, you may want to consider seeking the help of a professional eyewear technician. They can help you adjust your frames and ensure that they fit properly and comfortably.
Can Costa sunglasses be adjusted?
Yes, Costa sunglasses are designed to be adjustable to ensure a comfortable and secure fit. Most Costa sunglasses come with adjustable nose pads and temple tips that can be adjusted to better fit the shape of your face.
Once adjusted, your Persols should sit perfectly: clear vision, comfortable fit, and full sun protection whatever you’re doing. Small, careful tweaks are all it usually takes.
If the frames have Persol’s flexible stem system, tiny bends go a long way — and gentle warmth makes acetate models pliable. When in doubt, any optical shop will adjust designer frames like these, often free of charge. Content reviewed and updated in October 2026.
