Key point first

Uneven height in plastic frames should be checked through front twist, bridge contact, ear height, temple bends and acetate deformation.

01 · FRAME ALIGNMENT

Is the front twisted?

Start by checking the acetate front itself.

Heat or pressure can create subtle front-back or vertical differences between the rims.

If you adjust only the temples while the front is distorted, you may simply compensate for the wrong reference.

02 · BRIDGE CONTACT

Does the bridge contact both sides of the nose evenly?

If one side of the bridge sits deeper or only one edge presses, frame height and centering can change.

The wearer’s nose can also be asymmetric.

Because many plastic bridges have limited adjustment, good bridge-to-nose compatibility matters from frame selection onward.

03 · EAR HEIGHT

Different ear heights can affect the frame

A higher ear can make one side of the same temple geometry sit higher or lower.

Front-back ear position can also alter the temple path and the position of the front.

04 · TEMPLE BEND

The two temple bends do not have to be identical

If the ears differ, bend position and curvature can also differ.

A balanced result on the actual face is more important than making both sides look identical on a workbench.

05 · ACETATE DEFORMATION

The frame may have changed over time

Heat, repeated handling and poor storage can change acetate shape.

If the frame was fine before and recently began to tilt, inspect both frame deformation and hinge condition.

SOLUTION GUIDE

Solutions at a glance

The frame itself is distorted

Check the front for twist.

One side of the bridge presses more

Compare bridge contact on both sides.

One ear is higher

Adjust the temple bend to the actual ear.

It started tilting recently

Check acetate deformation and hinge condition.

GLANOS FITTING CHECK

GLANOS fitting check order

  1. Front
    Check the frame for twist.
  2. Bridge
    Compare left-right nose contact.
  3. Width
    Check temple path and side support.
  4. Temple bend
    Adjust to the actual ear heights.

CAUTION

Do not force only one temple to make the frame look level

If the source is the front or bridge, changing only the temple can create new problems. Restore the frame to a proper reference state first, then account for facial and ear asymmetry.
