Plastic eyeglass frames can be adjusted at home, but it's important to be careful as they can break easily. If your glasses are crooked, you can soak the temple corners in hot water for 30-60 seconds and then gently bend them to the desired shape. You can also use a hairdryer to heat the frames before gently bending them. If your glasses are too loose, you can tighten them by applying inward pressure to the ends of the arms. If they are too tight, you can loosen them by applying outward pressure to the warmed frames. If your glasses are pinching your nose, you can adjust the nose pads if your frames have them, or buy adhesive nose pads.

What You'll Learn
Adjusting plastic frames with a hairdryer
Firstly, ensure your hands are clean so that you do not risk damaging the frames. If your glasses are too loose or too tight, point the hairdryer at the bridge area and gently warm the frames up. This will allow you to more easily tighten or loosen them. You can also use a hairdryer to heat the arms of the glasses, but be sure to keep the lenses out of the direct line of the hot air. Once heated, apply gentle downward and inward pressure on the end of the arms to achieve a tighter fit. If the frames are too tight, do the opposite and make the angle less than 90 degrees.
It is important to note that this method is only suitable for minor adjustments. For more complex issues, it is recommended to visit a professional optician. Additionally, if your glasses have anti-reflective coatings, be aware that heat can damage these coatings.
Practice makes perfect when it comes to adjusting plastic frames with a hairdryer. It is a valuable skill to have, as it allows you to personalise the fit of your glasses for maximum comfort and vision.

Tightening plastic frames with hot water
Plastic frames typically need to be heated before they become flexible enough to adjust. To tighten plastic frames with hot water, follow these steps:
Step 1: Prepare the necessary items
You will need your glasses, a bowl of hot tap water, and a towel. Place the bowl of hot water on the towel to prevent spilling.
Step 2: Soak the temple end piece in hot water
Submerge one temple end piece (the part that goes over your ear) into the hot water for 30 seconds. Avoid soaking the lenses in water to prevent damage.
Step 3: Check the temperature
Carefully remove the temple from the water and touch the end to ensure it is not too hot.
Step 4: Hold the glasses face-up and support the frames
Hold the glasses with the lenses facing you. Place your four fingers under the temple, with your index finger resting at the natural temple bend to support the frames.
Step 5: Gently push the temple end down
Use your right hand to slowly and gently push the temple end down. You should feel it bend against your index finger. Adjustments should be slight, and you do not need to push too far.
Step 6: Repeat with the other temple end
After adjusting one side, repeat the process with the other temple end.
Additional tips:
- If your glasses keep sliding down your face, you can bend the earpiece closer to a 90-degree angle to tighten the fit.
- If the frames pinch your nose, you can adjust the nose pads outward or inward. An outward rotation helps with glasses that sit too high on the nose, while an inward rotation is suitable for frames that fall too low.
- If the arms of your plastic frames are challenging to adjust, you can run them under warm water to make them more flexible.
- You can also use a hairdryer to heat the frames before making adjustments.
- Always keep your glasses in a case when they are not in use to prevent misalignment.

Loosening plastic frames with hot water
Plastic frames typically need to be heated before they become flexible enough to adjust. One way to do this is by using hot water.
First, place a bowl of hot water on a towel. Then, place one temple end piece (the part that goes over your ear) into the water for 30 seconds to a minute. Make sure to keep the lenses out of the water to avoid damage.
After removing the temple from the water, test its temperature with your fingertip to ensure it's not too hot. Then, hold the glasses face-up with the lenses facing you. Place your four fingers under the temple, with your index finger resting at the natural temple bend to support the frames. Use your other hand to slowly and gently push the temple end down. You should feel it bend against your index finger. Remember, all adjustments should be slight. Repeat the process on the other side.
Alternatively, you can use a hairdryer to heat the plastic to a pliable state. Once the plastic is pliable, adjust it to the desired position and hold it in place until it cools down. The heat will break the molecular bonds in the plastic, and the subsequent cooling will form new ones.

Bending plastic frames by hand
Plastic frames typically need to be heated before they become flexible enough to adjust. You can use a hair dryer or hot water to heat the frames. Hold the hair dryer at least 10 inches away from the frames and move the warm, blowing air over the frames for at least 20 seconds. You can also submerge the temple ends of your glasses in hot water for 30-60 seconds. Remember to keep the lenses out of the water to avoid damage.
Once the frames are heated, you can start to bend them. 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. You can also bend the temple portion, the part of the frames that rest over each ear, by grasping the frames firmly with both hands and gently bending the curve of the temple over your index finger. Work in small, subtle movements, reheating the frames as necessary.
If your glasses are sliding down your nose, bend the temples down. If they are rubbing the back of your ears, bend the temples up. You can also straighten the entire temple and re-bend the curve to tighten the fit around your ear. If your glasses are slipping down your face, you can also apply downward, inward pressure to the ends of the arms to make them fit better behind your ear.
If your plastic glasses have plastic nose pads, you can adjust them by heating them with a hair dryer and then applying pressure to move them closer together or further apart. Move them closer together if the glasses are sliding down your nose and push them apart if the nose pads are sitting too high on your nose. Once you've adjusted the nose pads, cool them down with cold water to set them in place.

When to see a professional optician
While there are many ways to adjust your eyeglasses at home, there are some instances where you should seek the help of a professional optician.
Firstly, if your glasses are crooked or uneven, you can try adjusting them at home by following guides available online. However, if you are uncertain about your glasses' frame material or the specific adjustments required, it is best to consult a professional optician. Opticians are skilled in making precise adjustments to ensure your glasses fit comfortably and securely.
Secondly, if you experience issues with your glasses sliding down your face or pinching your nose, it could be due to the frame size or shape not suiting your face. Opticians can help select the perfect frame style and size for your face to prevent such issues. They can also advise on frame materials, as some materials, like metal, are more pliable and easier to adjust, while plastic frames often require heating before becoming flexible enough to adjust.
Thirdly, when purchasing new glasses, an optician will take measurements to ensure a proper fit. Ill-fitting glasses can cause discomfort and impact your vision. An optician will ensure the optical centres of the lenses align with your pupils and that the frames suit your lifestyle and personal style.
Finally, if you experience any ongoing issues with your eyewear, such as persistent eye strain, headaches, blurred vision, or dizziness, it is essential to consult your optometrist or optician. They can help identify if the issues are due to prescription errors, incorrect frame size, or other factors, and provide appropriate solutions.
While it is convenient to adjust your glasses at home, seeking professional help ensures that you receive expert advice and guidance tailored to your specific needs. Opticians are trained to understand the complex relationship between eyewear and vision health, providing you with glasses that enhance both your vision and confidence.
