Eyeglass frame adjustment is the process of correcting how your glasses sit on your face. A proper adjustment can improve comfort, balance, stability, and lens position.
If your glasses slide down your nose, pinch your skin, hurt behind your ears, or sit unevenly, you may not need new glasses. You may only need a professional Eyeglass Frame Adjustment San Francisco service.
A trained technician can adjust the temples, nose pads, bridge, frame angle, and overall alignment so the glasses fit your face better.
Why do my glasses keep slipping?
Glasses usually slip because the frame is too loose, the nose pads are not gripping properly, the temple arms are too wide, or the frame does not match your face shape.
In San Francisco, daily movement can make slipping glasses even more noticeable. Walking hills, commuting, working long hours, wearing headphones, or moving between indoor and outdoor temperatures can all affect how frames feel.
A technician may fix slipping glasses by adjusting the nose pads, tightening the temples, reshaping the frame, or improving the angle behind the ears.
How can slipping glasses be fixed?
The fix depends on the frame type.
For metal frames, the nose pads can often be adjusted closer together or angled better. The temple arms can also be tightened so the glasses stay secure without squeezing.
For plastic frames, the bridge and temples may need careful reshaping with controlled heat. This should be done professionally because plastic can crack if forced.
The goal is to make the glasses stable, not overly tight.
Why do my glasses pinch my nose?
Glasses pinch your nose when too much pressure is placed on a small area. This can happen if the nose pads are too close together, the frame is too narrow, or the glasses are sitting too low.
Heavy lenses can also increase pressure on the bridge of the nose.
A proper adjustment can spread the weight more evenly and reduce pressure marks. In many cases, small changes to nose pad position can make the glasses feel much more comfortable.
Why do my glasses hurt behind my ears?
Pain behind the ears usually means the temple arms are curved incorrectly or pressing too tightly.
The temple tips should rest comfortably behind the ears, not dig into the skin. If the curve is too sharp or the arm length is not right, the glasses can cause soreness after a few hours.
During an Eyeglass Frame Adjustment San Francisco visit, the technician can reshape the temple ends so they hold the glasses in place without causing pain.

Why do my glasses sit crooked?
Glasses may sit crooked because one temple arm is bent, the frame is twisted, the bridge is misaligned, or one side of your face sits slightly higher than the other.
It is important to understand that most faces are naturally uneven. A good glasses adjustment is not only about making the frame look straight on a table. It is about making the frame sit correctly on your face.
That is why professional adjustment is more accurate than trying to fix crooked glasses at home.
Can crooked glasses affect vision?
Yes, crooked glasses can affect how you see, especially if you wear progressive lenses, bifocals, strong prescriptions, or lenses with precise optical centers.
If your glasses sit too low, too high, too tilted, or too far from your eyes, you may look through the wrong part of the lens. This can cause eye strain, blurry vision, headaches, or discomfort.
Before assuming your prescription is wrong, it is smart to check whether the frame needs adjustment.
Why do new glasses feel uncomfortable?
New glasses can feel uncomfortable because the frame has not been adjusted to your face yet. Even if the prescription and lenses are correct, the fit may still need small changes.
Common new-glasses issues include slipping, tight temples, nose pressure, crooked fit, or lenses sitting too close to the eyelashes.
A professional adjustment can usually improve the fit quickly.
Can I adjust my glasses at home?
It is not recommended to force adjustments at home. Glasses can look simple, but frames are delicate. Bending them without the right tools can break hinges, loosen screws, crack plastic, or damage lens alignment.
Plastic frames often need heat before reshaping. Metal frames need pressure in specific areas. Rimless and semi-rimless frames require extra care because the lenses are part of the structure.
A professional adjustment is safer and more precise.
How often should glasses be adjusted?
You should get your glasses adjusted whenever they feel loose, tight, crooked, or uncomfortable. Some people need adjustments every few months, especially if they wear glasses daily.
You may also need adjustment after dropping your glasses, sleeping with them on, carrying them in a bag, or changing nose pads.
Regular adjustments can extend the life of your frame and improve daily comfort.
What happens during a professional frame adjustment?
A technician will usually inspect the frame, check the screws and hinges, look at how the glasses sit on your face, and ask where you feel discomfort.
They may adjust the nose pads, temples, bridge, frame angle, and temple tips. The process often involves small changes followed by checking the fit again.
The best adjustment is comfortable, balanced, and stable.
