How to resize your glasses at home

No matter how much you spend or how good your glasses are, at some point your glasses will probably be wobbly because they are a little too tight or a little too wide. 

Most of us get used to it when it happens. And ultimately, if the glasses still work, why bother? 

The fact is, loose glasses can be uncomfortable and cause unnecessary cranial strain, even if you don't realize it.

In fact, if the glasses are loose or just not fitting properly you're more likely to wrinkle your nose, pinch your ears or pull your cheeks up to keep them on your face. Spending a whole day, or days, doing this kind of facial contortion can cause headaches as if you weren't wearing glasses at all. 

Each type of glasses can face this type of problems (blue light glasses, sunglasses, plastic glasses, metal glasses...)

First and foremost, consider getting an eyeglass repair kit. 

It may sound silly, but you will probably need to use an eyeglass repair kit. You don't necessarily have to use the one with the miniaturized screwdriver, but you will at least need a screwdriver that fits the small screws in your glasses. A typical eyeglass repair kit usually includes replacement screws as well as nose pads, so that the glasses are comfortable and fit properly. 

So here are some tips you can learn to adjust your glasses right from home:

Check the frames

Glasses frame

If the glasses frames are not stable, you will need to adjust your glasses. Metal frames can be harder to resize. 

Use the screwdriver to adjust the hinge screw, which attaches the temple to the frame, to adjust your glasses. If one of the temple arms is higher than the left one for example, feel free to bend the right temple. Using hot water can also be very useful to adjust your glasses, but it depends on the frame materials. 

If it doesn't tighten, try replacing the screw on each temple. Be careful not to overtighten it, especially if it's plastic glasses or a plastic frame. Adjusting the temples of your glasses does not take as long as you might think, it can be done very quickly.

If the temple no longer moves smoothly, loosen it enough so that it moves freely, but without wobbling. Make sure that the angle at which they are tightest does not compress your head or remain too loose.

It is essential to try on the glasses throughout the process, whatever the type of frames.

Check the nose pads

If the pads are still intact and clean, check them for instability. If your nose pads don't fit properly, adjust them using the screwdriver in the repair kit, for example, or another of the same size. If you put the nose pads closer to your eye, make sure that they aren't too close or you'll get the same problem. 

If there are other problems (such as deformation, loss of padding, or other damage), and you can't adjust the pads, replace them with new nose pads that you've purchased beforehand. Also check the angle of the pads. If they are too tight, it is possible that the place where they are screwed into the frame is warped or tilted.

If nothing works

If the glasses still don't fit, repeat the above steps as necessary to ensure that everything has been done to your satisfaction. Be careful not to directly damage the lenses of your glasses. If you are still not satisfied, consider consulting an eyewear specialist. Your optician will usually readjust your eyeglass frames for free, if you stop by and explain your problem. 


For some people, buying eyeglasses can be worrisome because they are concerned about maintenance. This is also the case for those who do not wear prescription glasses, but for example only blue light glasses like those offered by GMG Performance.
