Adjusting Your Glasses for a Perfect Fit: A DIY Guide

Adjusting Your Glasses for a Perfect Fit: A DIY Guide

Having glasses that fit perfectly is crucial for both comfort and optimal vision. Glasses that are too loose can constantly slip down your nose, while those that are too tight can cause discomfort and even headaches. Fortunately, many common fit issues can be addressed at home with a few simple adjustments. This guide will walk you through the process of assessing the fit of your glasses and making necessary adjustments to achieve a comfortable and secure fit.

1. Assessing the Fit of Your Glasses

Before you start making any adjustments, it's important to accurately assess how your glasses are currently fitting. Here's what to look for:

Slipping: Do your glasses constantly slide down your nose? This is a common issue, especially with plastic frames.
Pressure Points: Do you feel any pressure points behind your ears, on your nose, or on the sides of your head? These can lead to discomfort and headaches.
Unevenness: Are your glasses sitting crooked on your face? This can affect your vision and overall appearance.
Distance from Eyes: Are your eyes properly centred in the lenses? The lenses should be positioned so that you are looking through the optimal part of the lens for your prescription.
Temple Length: Do the temple arms extend far enough to comfortably hook behind your ears without being too long or too short?

Once you've identified the specific issues with your glasses' fit, you can move on to making adjustments. Remember to proceed with caution and make small adjustments at a time to avoid damaging your frames.

2. Tightening Loose Screws

Loose screws are a common cause of glasses slipping or feeling unstable. Here's how to tighten them:

Identifying Loose Screws

Check the screws at the hinges of your glasses, where the temple arms connect to the frame. If you can see a gap between the screw head and the frame, or if the temple arms feel wobbly, the screws are likely loose.

Tightening the Screws


  • Gather Your Tools: You'll need a small screwdriver specifically designed for eyeglasses. These screwdrivers are typically very small and have a flat head. You can often find them in eyeglass repair kits or at pharmacies.

  • Position Your Glasses: Hold your glasses securely in one hand, with the screw facing upwards.

  • Tighten Carefully: Gently insert the screwdriver into the screw head and turn it clockwise until it's snug. Be careful not to overtighten, as this can strip the screw or damage the frame.

  • Test the Temple Arm: Check the temple arm to see if it feels more secure. If it's still loose, repeat the process, but be extra cautious not to overtighten.

Common Mistakes to Avoid

Using the Wrong Screwdriver: Using a screwdriver that's too large or the wrong type can damage the screw head and make it impossible to tighten. Always use a screwdriver specifically designed for eyeglasses.
Overtightening: Overtightening the screws can strip the threads or even crack the frame. Tighten gently until the screw is snug, but not overly tight.
Ignoring the Problem: Loose screws can lead to further damage and even loss of your glasses. Address loose screws as soon as you notice them.

If you're unable to tighten the screws yourself, or if the screws are stripped, it's best to seek professional assistance from an optician. You can learn more about Glassesonline and the services we provide.

3. Adjusting Nose Pads

Nose pads are the small cushions that rest on your nose and help to support your glasses. Adjusting them can significantly improve the comfort and stability of your glasses.

Identifying Nose Pad Issues

Slipping: If your glasses are constantly slipping down your nose, the nose pads may be too wide or not providing enough grip.
Pressure: If you feel pressure or pinching on your nose, the nose pads may be too narrow or positioned incorrectly.
Red Marks: Red marks on your nose after wearing your glasses indicate that the nose pads are too tight or applying pressure unevenly.

Adjusting the Nose Pads


  • Locate the Nose Pads: Identify the nose pads on your glasses. They are usually made of silicone or plastic and are attached to the frame with small arms.

  • Gently Bend the Arms: Use your fingers or a small pair of pliers to gently bend the arms that hold the nose pads. To make the nose pads wider, bend the arms outwards. To make them narrower, bend the arms inwards. Make small adjustments and try on your glasses after each adjustment to check the fit.

  • Adjust the Angle: You can also adjust the angle of the nose pads to better conform to the shape of your nose. Gently bend the arms up or down to change the angle of the nose pads.

  • Ensure Symmetry: Make sure that the nose pads are adjusted symmetrically on both sides of the frame. This will help to ensure that your glasses sit evenly on your face.

Common Mistakes to Avoid

Using Too Much Force: The arms that hold the nose pads are delicate and can be easily broken if you use too much force. Make small, gentle adjustments and avoid bending them too far.
Adjusting While Wearing: Never adjust the nose pads while you're wearing your glasses. This can be uncomfortable and could potentially damage your eyes.
Ignoring the Material: Be mindful of the material of your nose pads. Some materials are more pliable than others. Metal nose pad arms require more care than silicone ones.

If you're uncomfortable adjusting the nose pads yourself, or if you have metal frames, it's best to seek professional assistance. Check our services for more information on how we can help.

4. Adjusting Temple Arms

The temple arms are the part of your glasses that extend behind your ears. Adjusting them can improve the comfort and stability of your glasses, especially if they're too tight or too loose.

Identifying Temple Arm Issues

Slipping: If your glasses are slipping, the temple arms may not be providing enough grip behind your ears.
Pressure: If you feel pressure behind your ears or on the sides of your head, the temple arms may be too tight.
Unevenness: If your glasses are sitting crooked, one temple arm may be bent or misaligned.

Adjusting the Temple Arms


  • Heat the Temple Arms (for Plastic Frames): If you have plastic frames, you'll need to heat the temple arms slightly to make them more pliable. You can do this by running them under warm water for a few seconds or by using a hairdryer on a low setting. Be careful not to overheat the frames, as this can damage them.

  • Gently Bend the Temple Arms: Use your fingers to gently bend the temple arms. To tighten the fit, bend the arms inwards towards your head. To loosen the fit, bend the arms outwards away from your head. Focus on the area where the temple arm curves behind your ear.

  • Adjust the Angle: You can also adjust the angle of the temple arms to better conform to the shape of your head. Gently bend the arms up or down to change the angle.

  • Ensure Symmetry: Make sure that the temple arms are adjusted symmetrically on both sides of the frame. This will help to ensure that your glasses sit evenly on your face.

Common Mistakes to Avoid

Using Too Much Heat: Overheating plastic frames can cause them to warp or become brittle. Use warm water or a hairdryer on a low setting and avoid holding the heat source too close to the frames.
Bending Metal Frames: Metal frames should only be adjusted by a professional optician. Attempting to bend metal frames yourself can easily damage them.
Ignoring the Curve: The curve of the temple arm is designed to fit comfortably behind your ear. Avoid straightening the curve or bending it too sharply.

5. When to Seek Professional Assistance

While many fit issues can be addressed at home, there are certain situations where it's best to seek professional assistance from an optician.

Metal Frames: Adjusting metal frames requires specialised tools and techniques. Attempting to adjust them yourself can easily damage them.
Complex Adjustments: If you need to make significant adjustments to the shape or alignment of your frames, it's best to consult with an optician.
Broken or Damaged Frames: If your frames are broken or damaged, don't attempt to repair them yourself. Take them to an optician for professional repair.
Persistent Discomfort: If you've tried adjusting your glasses yourself and are still experiencing discomfort, it's possible that the frames are not the right size or shape for your face. An optician can help you find frames that fit properly.
Vision Changes: If you're experiencing changes in your vision, it's important to see an optometrist for an eye exam. Your glasses may need to be adjusted or your prescription may need to be updated. You can check frequently asked questions or contact us to book an appointment.

6. Tools You May Need

Here's a list of tools that you may find helpful for adjusting your glasses:

Eyeglass Screwdriver: A small screwdriver specifically designed for eyeglasses.
Small Pliers: A small pair of pliers for gently bending nose pad arms.
Warm Water or Hairdryer: For heating plastic frames to make them more pliable.
Soft Cloth: For cleaning your glasses and protecting them from scratches.
Magnifying Glass: For inspecting small screws and details.

By following these tips and instructions, you can adjust your glasses for a perfect fit and enjoy comfortable, clear vision. Remember to proceed with caution and seek professional assistance when needed. A well-fitting pair of glasses is an investment in your comfort and eye health.
