STEP 01

Start With a Safe Fit Check

Place your glasses on a clean, flat surface and look for visibly loose screws, twisted temples, bent nose pads, or an uneven frame. Put them on using both hands and check whether the lenses sit level and the temples rest comfortably along your head.

Before you begin: Use a soft microfiber cloth and good lighting. Avoid force, heating tools, household pliers, adhesives, and bending the bridge or lens mounts.

STEP 02

If Your Glasses Slip Down

Slipping can result from nose-pad positioning, frame width, temple shape, or the overall frame size.

• Adjustable nose pads: Check for loose or uneven pads. Small repositioning may be possible, but fragile pad arms are best adjusted by an optician.
• Saddle bridges without nose pads: Do not try to bend the fixed bridge to change the fit. Check whether the selected frame dimensions suit your nose and face.
• Temple tips: If the ends do not sit securely around your ears, ask an optician to assess the temple curve.

STEP 03

If the Temples Feel Too Tight

Pressure behind the ears or at the sides of your head may mean that the frame width or temple curve is not suitable. Take the glasses off if they cause discomfort. An optician can check the fit and make material-appropriate adjustments if the frame design allows.

For metal, acetate, and titanium frames, adjustment methods vary. Heating acetate at home or repeatedly bending metal components can damage the finish, hinges, or lens mounting points.

STEP 04

If the Frame Looks Uneven

Check the fit in a mirror with your head level. A frame that appears tilted may be affected by temple alignment, nose-pad position, or natural differences between your ears. Avoid bending the bridge, hinges, or rims to straighten it yourself; an optician can identify the correct adjustment point.

STEP 05

Check Screws and Nose Pads

If you notice a loose hinge or rim screw, stop wearing the glasses until it can be secured. A correctly sized precision screwdriver may be used with very light pressure on an accessible standard screw, but do not force resistant screws or attempt to alter the fit by loosening them.

If a screw is stripped or missing, or a pad arm appears bent, professional service is safer. Use the correct replacement component for your model.

STEP 06

Special Care for Cable Temples & Rimless Frames

Cable temples (ear-hook arms): These curved temples are designed to follow the ear, but their flexibility and adjustment range depend on the specific model. Avoid repeated twisting, sharp bends, or pulling the cable ends open. Ask a qualified optician for fitting help.

Rimless or hingeless frames: The lens mounting areas and flexible components can be sensitive to concentrated force. Do not reshape them at home.

STEP 07

When to Get Professional Help

Visit a qualified optician if the frame is visibly bent, the lenses move, the bridge is distorted, screws are damaged, the glasses remain uncomfortable, or you cannot correct an issue through ordinary cleaning or checking. Professional adjustment is particularly important for titanium, rimless, prescription, and made-to-order eyewear.
