Plastic frames are a popular choice for eyeglass wearers due to their versatility and style. However, achieving the perfect fit can be challenging, and ill-fitting glasses can cause discomfort and even lead to headaches, eye strain, and vision problems. To adjust plastic frames, it is usually necessary to heat the frame first, either by running it under hot water, using a hair dryer, or employing glass bead pans or hot air blowers. Once the frame is heated and softened, it can be carefully bent to achieve the desired fit. This may involve adjusting the arms of the glasses or the nosepads to ensure the glasses sit comfortably on the face and provide clear vision.

Heat the plastic frames with hot water or a hair dryer before adjusting
To adjust plastic frames, it is important to first heat the plastic to make it more malleable. This can be done by running the frames under hot water for 30-60 seconds, or by using a hair dryer. If you choose to use a hair dryer, move it back and forth over the area you want to adjust, similar to how you would use a hair dryer to dry your hair. Avoid holding the hair dryer in one place for too long, as this could damage the frames.
Once the frames are heated, you can begin to carefully bend them to your desired shape. It is important to be gentle during this process, as too much bending can damage the frames. After you have achieved your desired shape, cool the frames by dunking them in cold water. This will set the shape and prevent the plastic from returning to its original form.
It is worth noting that some types of plastic may be more difficult to adjust than others. For example, materials like titanium, memory plastic, and aluminum alloy are known to resist adjustment. If you are unsure about the material of your frames or are uncomfortable with the heating and bending process, it is always best to consult a professional optician for assistance.
Additionally, when heating and adjusting plastic frames, it is important to take the necessary safety precautions. Be cautious when using hot water or a hair dryer to avoid accidental burns. Also, be aware that heating plastic may release toxic fumes, so ensure adequate ventilation during the process.
By following these steps and taking the necessary precautions, you can safely and effectively adjust your plastic frames for a comfortable and secure fit.

Bend the earpiece closer to a 90-degree angle to tighten the fit
If your glasses keep sliding down your face, you can adjust the fit by bending the earpiece closer to a 90-degree angle. This adjustment will ensure your glasses stay in place and don't require frequent pushing up.
Before bending the earpiece, it is important to heat the plastic frame. Running the earpiece under hot water or heating it with a hairdryer for 30-60 seconds will make the plastic pliable and ready for bending. Avoid bending the earpiece without first heating the frame, as this can cause the plastic to break.
Once the plastic is heated, gently bend the earpiece closer to a 90-degree angle. This will tighten the fit behind your ear. Be careful not to overcorrect, and try to preserve the natural curve behind your ear. After making adjustments, test out the glasses to ensure a comfortable and secure fit.
If your glasses continue to slide down your nose, you can also try adjusting the screws that attach the arms to the lenses. Tightening these screws can help keep the lenses secure within the frames and prevent slippage. However, be careful not to over-tighten the screws, as this can damage the plastic or metal.

Adjust the nosepads to sit higher or lower on your nose
Adjusting the nosepads to sit higher or lower on your nose is a simple process that can greatly improve the comfort and fit of your glasses. Firstly, ensure your hands are clean so you don't risk damaging or smudging the frames or lenses. If your plastic glasses frames are sitting lower on your nose than desired, the temples may be too wide. In this case, you can adjust the temple arms to a tighter fit by running them under warm water for 30-60 seconds and then bending them closer to a 90-degree angle. If the arms are too tight, do the opposite and adjust them to a wider angle.
If your glasses are still sitting too low on your nose, you can adjust the nosepads. To lower the frames, adjust the nosepads outward, away from each other and the lenses. To raise the frames, adjust the nosepads inward, towards each other. Make small adjustments, as only a slight change is needed. You can use your fingers to make these adjustments, or for more precision, use nose pad pliers. To use the pliers, line up the gap on the pliers with where the frames connect to the nosepad and gently squeeze.
If your glasses are crooked, it might be that one side is higher than the other. To fix this, place your glasses on a flat surface and observe if both temples are touching the table. If one side is higher, heat the temple of that side by immersing it in warm water for 30-60 seconds, then bend the temple tip down using slow and steady pressure.

Soak the arms of your glasses in warm water before applying pressure
Soaking the arms of your glasses in warm water is a recommended method to adjust plastic frames. This process makes the plastic pliable, allowing you to bend it into the desired position. It is important to be cautious when applying heat to plastic, as it can be susceptible to snapping even when heated.
To begin the process, fill a container with warm water. Ensure that the water is not too hot, as this could damage the frames. Submerge the arms of the glasses in the water for 30 to 60 seconds. This timing is crucial, as it ensures that the plastic becomes pliable without overheating. After soaking, carefully remove the glasses from the water and dry the arms with a soft cloth or tissue.
Once the arms are sufficiently dried, you can proceed with the adjustment. It is recommended to work on one arm at a time to ensure precision. Hold the glasses with the lenses facing you and place your fingers around the temple arm for a secure grip. Gently apply upward and outward pressure on the end of the arm, adjusting it to achieve the desired width. It is important to make minor adjustments and gradually increase pressure to avoid overcorrection.
Throughout the process, it is essential to try on the glasses periodically to test the fit. This allows you to make any necessary adjustments and ensure that the arms are comfortable and secure. Remember to treat the plastic arms with care, as excessive force can lead to snapping or permanent damage. Always make minor adjustments and check the glasses frequently to achieve the perfect fit.

Visit a professional optician for help with adjusting your frames
While there are some at-home methods for adjusting your plastic frames, visiting a professional optician is a foolproof way to ensure your glasses are modified with precision. Opticians are highly capable of modifying any type of plastic frame, and with their expert help, you'll have a perfectly adjusted pair of glasses in no time.
Opticians can help with a range of adjustments, from tightening your frames to ensuring the optical centre of the lens is directly in front of your pupils. They can also adjust the arms of your glasses, which are the parts of the frames that hook behind your ears. This is a common issue, as one side of your frames may appear higher than the other, requiring you to bend the arms up or down at the hinge or where the arm bends behind your ear.
If your frames do not have nose pads, opticians can adjust the temple tips to achieve your desired fit. They can also advise on how to prevent your glasses from sliding down your nose, which often occurs due to factors like facial oil, perspiration, and sunblock. Opticians may suggest bending the back of the temples tighter around your ears or using gripping wax or nose pads to prevent slippage.
Most opticians will adjust your glasses for free, and it is always better to seek their expertise than risk damaging your frames by attempting adjustments yourself.
