01 · MULTIPLE CHANGES

One movement can change several fitting variables

Moving a pad arm in one direction may change not only spacing but also height, angle and the distance from the face.

Which variables change and in which direction depends on the arm geometry, adjustment direction and nose shape.

That is why even a small adjustment should be judged in the context of the full wearing position.

A pad arm behaves like a small bent lever: moving one point can change the position and angle at its end at the same time. Simple finger pressure to narrow or widen the pads therefore rarely changes only one variable and can quickly increase left-right asymmetry.

02 · LEFT-RIGHT BALANCE

It is easy to create left-right differences

When each side is moved by hand, it is difficult to reproduce the same reference on both sides.

If one pad becomes higher or farther forward, the frame can tilt, one side of the nose can take more pressure, and vertex distance can differ left to right.

03 · METAL FATIGUE

Repeated bending stresses the metal

Repeatedly correcting and reversing an adjustment can accumulate fatigue in the thin pad arm.

The degree varies with material and construction, but repeated bending increases the risk of permanent deformation or breakage.

04 · FRAME ALIGNMENT

The real cause may not be the nose pads

Slipping or pressure can originate from the frame front, overall width, temple spread or the behind-ear bend.

Adjusting only the nose pads without finding the cause can increase nose pressure while leaving the original problem unresolved.

If slipping is actually caused by frame width or spread temples, narrowing the nose pads may make the frame feel temporarily more secure while increasing nasal pressure. The main risk of self-adjustment is often not the force itself but compensating the wrong part because the cause was never separated.

05 · LENS POSITION

Lens position also changes

Nose-pad adjustment can change wearing height, vertex distance and sometimes pantoscopic tilt.

With progressive or high-prescription lenses, the change in lens position matters in addition to comfort.

Once lenses are already edged and mounted, changing the nose pads can change the relationship between the eyes and the lenses. If vision or dizziness changes after adjustment, recheck wearing height, vertex distance, pantoscopic tilt and frame alignment before calling it adaptation.

SOLUTION GUIDE

Solutions at a glance

1. Is the frame itself straight?

Check front alignment first.

2. Is pad contact stable?

Look for edge pressure.

3. Do the two pads differ in height or angle?

Compare the pads and arms.

4. Where is the cause in the whole fit?

Adjust only the necessary part and as little as possible.

GLANOS FITTING CHECK

GLANOS fitting check order

  1. Front
    Check the frame reference state.
  2. Nose pads
    Check height, spacing, angle and contact.
  3. Width
    Check lateral support.
  4. Temple bend
    Check support behind the ears.

CAUTION

Do not repeatedly narrow and widen the pads by hand

Being adjustable does not mean the parts can be repeatedly moved in any direction without consequence. Find the cause first and make the minimum adjustment appropriate to the arm structure.
