Few things are more annoying than sunglasses that fit perfectly in the store and slide off your face a week later. Heat, wear, and wide temples gradually stretch most frames — but ‘stretched out’ doesn’t mean ruined.
Here’s how to bring them back to a snug, secure fit.
Fortunately, there are some easy fixes that you can do to get your sunglasses looking and fitting perfectly again. Here’s what you need to do to fix stretched out sunglasses:
- Use an Adjustable Nose Pads: The best way to keep your sunglasses from stretching out is to use an adjustable nose pad. These are available at most eyewear stores and are designed to help keep your sunglasses comfortably in place. All you have to do is adjust the nose pads to the right size for your face and then press them firmly onto your nose. This should help keep your sunglasses from stretching out.
- Use Heat to Adjust the Frames: If your sunglasses are made from plastic or metal, you can use a bit of heat to reshape the frames and get them back to the original shape. All you need to do is hold the sunglasses over a heat source, such as a hairdryer, and then use your fingers to carefully reshape the frames. This should help make your sunglasses fit snugly and comfortably again.
- Use a Soft Cloth and Soap: If your sunglasses are too loose, you can use a soft cloth and a mild dish soap to make them fit better. Just wet the cloth with the soap and then gently rub it over the frame of the glasses. This should help tighten the frame and make them fit more snugly.
- Take them to an Optometrist: If all else fails, you can take your sunglasses to an optometrist to get them adjusted professionally. This is the safest option, as the optometrist will have the right tools and know-how to make sure your sunglasses fit perfectly.

Frequently Asked Questions
How do you make plastic sunglasses tighter?
If your plastic sunglasses are too loose and you want to make them tighter, there are a few steps you can take:
Adjust the nose pads: Many plastic sunglasses come with adjustable nose pads that can be moved to better fit the shape of your nose. You can use a small screwdriver to loosen or tighten the screws on the nose pads to adjust their position.
Adjust the temple tips: The temple tips, or earpieces, of your sunglasses may also be adjustable. You can use a small screwdriver to loosen or tighten the screws on the temple tips to adjust their position and secure them more firmly to your head.
Use a nose pad grip: If the nose pads of your sunglasses are not adjustable or you are unable to adjust them enough to get a secure fit, you may be able to use a nose pad grip to improve the fit. A nose pad grip is a small, adhesive pad that you can place on the nose pads to provide a firmer grip and improve the fit of your sunglasses.
By following these steps, you should be able to make your plastic sunglasses tighter and achieve a more secure and comfortable fit.
Heat, gentle bending, and cooling — that’s the whole technique for reshaping stretched frames. Done carefully, most pairs come right back to a comfortable, secure fit.
The key principle: warmth makes most frame materials pliable, so small, slow bends are all you need. Polycarbonate sport frames are the exception — they’re designed to flex back and rarely hold a new shape, so a strap may serve you better than repeated bending.
