Plastic spectacle frames can be adjusted at home, but in some cases, they may need to be taken to a professional. Misalignment is a common issue with glasses, which can be caused by bumping or dropping them, or even just by wearing them for a long time. To adjust plastic spectacle frames, the frame usually needs to be heated to make it flexible. This can be done by running the plastic parts under hot water for 30 seconds to 1 minute, or heating with a hairdryer for 2-3 minutes. Once heated, the frame can be carefully bent to achieve the desired fit. However, some plastic frames may resist adjustment, such as those made with memory plastic.

What You'll Learn
Plastic frames need to be heated before adjustments
First, run the temple ends of your glasses under hot tap water for 30 seconds to a minute. You can also submerge the ends in a bowl of hot water for the same amount of time. Ensure that you keep the lenses out of the water to avoid damage.
After heating, carefully dry the frame with a towel and test the temperature with your fingers to ensure it is not too hot. Then, hold the glasses face-up with the lenses facing you. Place your thumbs on the underside of the frame temple, right where the curve begins. Position your index fingers on top of the bend.
Now, gently push downward with your index fingers while your thumbs push up. Make only slight adjustments, as small changes can significantly impact the fit. Try to preserve the natural curve behind your ear and avoid overcorrection.
If your glasses are too tight and hurting the back of your ear, you can adjust the earpiece to be less of an angle. On the other hand, if your glasses are too loose and sliding down your face, bend the earpiece closer to a 90-degree angle to tighten the fit.

Use hot water or a hairdryer to heat the frames
If you want to adjust your plastic spectacle frames, you can use hot water or a hairdryer to heat the frames before bending them. This method is ideal for making slight adjustments to the frame.
Firstly, ensure your hands are clean so you do not risk damaging the frames with dirt or oil from your fingers. Then, run the plastic parts of the frames under hot water or use a hairdryer to heat them for 20 to 60 seconds. Be careful not to overheat the frames, as this can lead to deformation.
Once the frames are warm, you can carefully bend them to achieve the desired fit. If you need to adjust the arms of the glasses, apply gentle pressure to the ends of the arms while trying on the glasses until you get the right amount of space. Remember that too much bending will damage your spectacle frames.
If your frames slide down your face, you can bend the earpiece closer to a 90-degree angle to tighten the fit. Conversely, if the earpiece is too tight and hurts the back of your ear, adjust it to be less of an angle.
By using hot water or a hairdryer to heat your plastic spectacle frames, you can make slight adjustments to achieve a comfortable and secure fit.

Adjust the arms to prevent pinching your nose
Adjusting the arms of your plastic spectacle frames can help prevent your glasses from pinching your nose. This is a simple process that can be done at home, but it is important to be careful to avoid damaging your frames. Firstly, ensure your hands are clean and dry. Then, run the arms of your glasses under hot water for 15 to 25 seconds, or soak them in warm water for 30-60 seconds. This will make the plastic pliable, allowing you to adjust the arms without snapping them.
Once the plastic is warm, gently apply upward and outward pressure on the end of the arms to achieve a wider fit. Make slight adjustments at a time, testing the fit of your glasses after each change. You can always adjust them again later if you find they are still uneven. It is important to avoid overcorrection and preserve the natural curve of the arms behind your ears.
If your glasses are still pinching your nose after adjusting the arms, you may need to adjust the nose pads. First, check that your nose pads are symmetrical by holding your glasses up at eye level. If the nose pads are uneven, gently bend them into the correct position so that they are in the same position on each side. You can also try pulling the nose pads towards the centre of the frames and away from the lenses, being careful not to bring them too close together.
If your glasses continue to pinch your nose, you may need to replace the nose pads with wider ones. Nose pads that are too narrow can cause your glasses to slip down your face, while wider nose pads will provide more support and prevent pinching. You can buy replacement nose pads in a glasses repair kit or online, and they can be easily snapped or screwed into place.

Tighten loose glasses to prevent them from sliding
If your plastic glasses are loose and tend to slide down your nose, there are several ways to tighten them. However, it is important to note that some glasses are more challenging to adjust than others and may be prone to breaking. Therefore, it is always recommended to consult an optician for adjustments whenever possible.
One common method to tighten plastic spectacle frames is to heat the temple ends or arms of the frames. This can be done by running them under hot or warm water for 15 to 60 seconds, depending on the source. Alternatively, a hairdryer can be used to heat the frames, but this method carries a risk of damaging the frames and lenses. Once heated, the temple ends can be gently bent downwards to tighten the glasses. It is important to avoid exerting too much force when bending the frames to prevent damage.
Another way to tighten plastic spectacle frames is to adjust the nose pads. This method is more applicable to metal frames with adjustable nose pads, but some plastic frames also have adjustable nose pads. To tighten the glasses, the nose pads should be gently bent inwards. For metal frames, this can be done by pinching the nose pad with the thumb and finger, or with needle-nose pliers. For plastic frames without adjustable nose pads, anti-slip adhesive nose pads can be purchased to improve the fit.
Additionally, adjustments can be made to the screws that attach the arms to the lenses of the glasses. This can be done with a small screwdriver, typically found in eyeglass cleaning and repair kits. However, it is important to be cautious when tightening the screws to avoid over-tightening, as this can damage the plastic or metal of the frames.
When making adjustments, it is important to work in small, careful steps to avoid damage. It is also recommended to fine-tune the fit by testing the glasses on your face after each adjustment.

Check for loose screws and tighten with a screwdriver
Before you adjust your plastic spectacle frames, it's important to check for loose screws at the temple corners, or hinges, of the frames. Sometimes, these screws can become loose or even fall out, causing your frames to feel wobbly or uncomfortable. You can avoid this by regularly checking on the screws and tightening them with a screwdriver.
To do this, you'll need an eyeglass repair kit that includes a small screwdriver, or any screwdriver that fits the screw head. If a screw falls out or an arm becomes detached, it's best to have an optician adjust your glasses professionally rather than attempting to fix them yourself.
If your glasses are too loose, they may slide down or fall off your face, while glasses that are too tight may cause discomfort and headaches. Adjusting the temples, or arms, of your glasses is a common way to address these issues. A slight change in their position can keep glasses from sliding forward or feeling uncomfortable behind your ears.
Before making any adjustments to plastic spectacle frames, it's important to heat the frames. This can be done by running the plastic parts under hot water or heating them with a hairdryer for 2-3 minutes. Once the frames are heated, you can then tighten the screws with a screwdriver.
By regularly checking for loose screws and tightening them with a screwdriver, you can help ensure that your plastic spectacle frames fit comfortably and securely on your face. This simple maintenance routine can make a big difference in your overall comfort and help extend the life of your glasses.
