Plastic eyeglass frames are a popular choice for eyewear due to their versatility and range of colours. However, they may not always fit properly and adjustments are often needed. This can be done at home by applying heat and pressure to the frames. Firstly, it is important to identify the area that requires adjustment. This could be the temple arms, the nose pads, or the bridge. Once the area is identified, the plastic part can be heated with hot water or a hairdryer for 30 seconds to 2 minutes and then carefully bent to achieve the desired fit. It is important to make small adjustments to avoid damaging the frames. If the frames are too tight, bend them slightly away from your face to relieve the pressure. If they are too loose, bend them closer to a 90-degree angle to tighten the fit.

What You'll Learn

Heat plastic frames with hot water or a hairdryer before bending
To shape plastic eyeglass frames, you will need to heat the plastic before bending it. Two common methods for heating the frames are with hot water or a hairdryer.
If you choose to use hot water, it should be noted that some sources recommend using warm water instead of boiling water, as boiling water can damage plastic lenses. It is also recommended to use a damp cloth as insulation between the water and the frames to protect them from overheating.
If you choose to use a hairdryer, it is best to use medium heat and keep the hairdryer moving so that no single area gets too hot. This will help prevent warping or melting.
It is important to be cautious when applying heat to plastic eyeglass frames, as some types of plastic cannot be adjusted, and others may be damaged by heat. If you are unsure about the type of plastic your frames are made of, it is recommended to call the manufacturer and ask about adjustment procedures before applying heat.
Once the plastic is heated and softened, you can begin to bend it into the desired shape. This can be done by hand or with needle-nose pliers, which can provide more precision. It is important to be patient during this process and work slowly to avoid cracking or breaking the frames.

Bend the temple arms to adjust the frame's width
To adjust the width of your plastic eyeglass frames, you will need to bend the temple arms. This process is best done by an eye care provider, but it can be done at home if necessary.
First, check the material of your frames. Some materials, like titanium, memory titanium, memory plastic, and aluminum alloy, are difficult to adjust. If your frames are made of plastic, you will need to heat the arms with warm water or a hairdryer before bending. Stainless steel or plastic/acetate temple arms with embedded stainless steel rods are more readily adjustable.
Next, stand in front of a mirror wearing your glasses. Look down and peer into the mirror to check the alignment of your frames. If the left lens is closer to your face, gently pull the left temple arm in or push the right temple arm out. If the right lens is closer to your face, gently pull the right temple arm in or push the left temple arm out. Make minor adjustments, checking the glasses in the mirror as you go, to avoid over-correcting.
To make the glasses tighter on your face, bend the earpieces inwards. To make them looser, bend the earpieces outwards. The temples should bend at about a 45-degree angle, starting just behind your ear. If the bend in the temple starts before your ear, you will need to loosen the temple arms.

Adjust the nosepads to get the right height
Adjusting the nosepads of your plastic eyeglass frames to get the right height is a simple process, but it requires patience and precision. Here is a step-by-step guide to help you achieve the perfect fit:
First, ensure your hands are clean and dry to avoid leaving any marks or smudges on the lenses or frames. Cup the outside left lens area firmly in your left hand, with the nosepads facing upwards. Using your right hand, grasp the bridge of the frame securely.
Now, it's time to make the necessary adjustments to the left nosepad. Using your right hand, gently pinch the nosepad with your thumb and index finger. Make small and gradual adjustments by wiggling the nosepad outwards or inwards until it sits comfortably against your nose. Remember to make minor changes to avoid over-adjusting. The goal is to achieve a secure and comfortable fit without exerting too much force on the delicate nosepads.
Once you're satisfied with the position of the left nosepad, it's time to move on to the right side. Simply repeat the same process on the right nosepad, ensuring that you make equal adjustments to maintain symmetry. Use your right hand to grasp the bridge and your left hand to adjust the nosepad, mirroring the adjustments made on the left side.
After adjusting both nosepads, take a moment to assess the overall fit. Put on your glasses and check if they feel secure and comfortable on your nose. If needed, make small fine-tunings to ensure both nosepads are at the desired height and position. Remember, it's better to make gradual adjustments than to risk over-tightening or bending the nosepads too far.
By following these steps, you can effectively adjust the nosepads of your plastic eyeglass frames to achieve the right height and a personalized fit. Enjoy your perfectly adjusted glasses!

Bend the earpiece to a 90-degree angle to tighten the fit
If your plastic eyeglass frames are sliding down your face, you can adjust the earpieces to form a 90-degree angle to tighten the fit.
Firstly, you need to make the plastic pliable by heating it. You can do this by running the earpiece under hot water or heating it with a hairdryer for 30-60 seconds. It is important to never try to bend or adjust any plastic frame parts without first heating up the frame, as this will cause the frame to break.
Once the plastic is heated, you can carefully bend the earpiece to form a 90-degree angle. This will tighten the fit and prevent your glasses from sliding down your face. If the glasses are too tight and hurting the back of your ear, do the opposite and make the angle less than 90 degrees.
You can also try adjusting the nose pads to achieve a more comfortable fit. If the eyeglasses sit too high on your face, move the nose pads further apart. If the eyeglasses sit too low, pinch the nose pads closer together. Make sure to bend each of the nose pieces together or apart at equal distances to keep the symmetry of your glasses.
If you are still having issues with slippage, try using a gripping wax or nose pads with nose pelts to stop the slippage. Glasses that pinch your nose can be uncomfortable and cause headaches or migraines.

Push the arms inward and downward to prevent slipping
If your plastic eyeglass frames are slipping, you can adjust them at home by pushing the arms inward and downward. Firstly, heat the plastic by running the frames under hot water for 15 to 25 seconds, or submerging them in warm water for 30-60 seconds. This will make the plastic pliable, allowing you to adjust them without snapping. Place the temple arms in the water, ensuring the lenses stay dry.
Once the plastic is warm, remove the glasses from the water and dry the ends. Hold the glasses face-up with the lenses facing you. Then place the four fingers of your left hand under the temple, with your index finger resting at the natural temple bend to support the frames. Use your right hand to slowly and gently push the temple end down. You should feel it bend against your index finger. Repeat this process on the other side.
Only slight adjustments are necessary, so be careful not to push too far. After making adjustments, test the glasses to ensure they are comfortable and secure. If they are still slipping, you may need to bend the arms further, or try using glasses wax or silicone nose pads.
If you are unsure about adjusting your glasses, or if they are still slipping after adjustments, consider taking them to an optician for professional fine-tuning. Many optical centres offer free adjustments, and it is important to ensure your eyewear is adjusted properly to protect your eye health.
