What changes when nose-pad height changes?

01 · WEARING HEIGHT

Nose-pad height affects how high the frame sits

If the point where the pads support the nose changes, the frame can move up or down.

This also changes the relative position of the lens centers and the eyes.

When pad height is changed, judge how far the frame itself actually moves on the face. The same movement of a pad arm can produce a different wearing-height change depending on its geometry, so the eye-to-lens relationship is more important than the pad coordinate by itself.

02 · LEFT-RIGHT LEVEL

Different pad heights can affect frame tilt

If one pad supports the frame higher than the other, the two lens heights and overall tilt can change.

When one side looks higher, compare pad height, angle and contact along with the alignment of the frame front.

Changing only one pad can affect both vertical level and frame rotation. Before moving one side because one lens appears higher, distinguish front distortion, nasal asymmetry, unequal ear height and unequal temple forces.

03 · VERTEX DISTANCE

Height adjustment can also change front-back distance

Depending on the direction in which the pad arms are moved, the frame can come closer to or farther from the face.

If eyelashes or cheeks begin to contact after a height adjustment, recheck vertex distance and pantoscopic tilt as well.

Height adjustment can also move the pad arms forward or backward, changing vertex distance and pantoscopic tilt. With higher powers or lenses designed from position-of-wear data, even a modest change may be perceptible, so the final wearing position should be checked again.

04 · LENS POSITION

This is especially important with progressive lenses

With progressive lenses, it matters which vertical part of the lens the eye looks through.

If pad adjustment changes wearing height, it can alter the original fitting height, so any change in vision should be rechecked.

With progressive lenses, the objective is not simply to place the frame as high as possible. The fitting height used for the design and measurements needs to be reproduced in the final fit. If vision changes after adjustment, verify frame position and fitting references before attributing everything to adaptation.

05 · PRESSURE

Do not increase pressure just to raise the frame

Pushing the pads too far inward to raise the glasses can increase pressure on both sides of the nose.

Wearing height, nose contact, vertex distance and long-wear comfort should be balanced together.

Trying to gain height by excessively narrowing the pads or pushing the arms inward may raise the support point while concentrating pressure. Evaluate wearing height, vertex distance, broad pad contact and long-term comfort together.

GLANOS FITTING CHECK

GLANOS fitting check order

1. Front
   Confirm frame reference alignment.
2. Nose pads
   Check height, angle and any vertex-distance change together.
3. Width
   Check lateral support.
4. Temple bend
   Stabilize the final wearing position.

CAUTION

Higher is not automatically better
