01 · NOSE PAD
Are the nose pads providing stable support?
If pad angle does not match the nose or contact is unstable, the frame can move forward more easily.
Old pads can become hard or their surface characteristics can change.
Silicone pads may help some wearers, but check position and angle before changing material alone.
02 · FRONT WEIGHT
Check front weight and center of mass
Large lenses, thick lenses or a heavy frame front can move the center of mass forward and increase the sensation of forward shift.
A high prescription alone does not always shift the center of mass forward, so consider lens size, material, thickness and frame construction together.
If you simply narrow the nose pads to compensate, nose pressure can increase.
03 · TEMPLE SPREAD
Are the temples spread too far outward?
If the frame is too wide or the temples flare outward excessively, lateral support is reduced.
The frame can then move forward more easily.
Temples that look spread do not always need to be bent inward at the middle. First distinguish a wide front, an outward endpiece or hinge angle, and an acquired asymmetry in the temples. Correcting the wrong location can increase temple pressure while leaving the forward migration unchanged.
04 · TEMPLE BEND
Is the behind-ear bend too loose?
If the temples do not engage stably behind the ears, the frame can move forward.
But an excessively deep bend can create ear pain, so use only the amount of rear support needed.
The position as well as the amount of the ear bend matters. A bend that begins too far forward can concentrate pressure or feel as if it pushes the frame away, while one that starts too far back may provide little control of forward motion. The bend should follow the ear with only enough contact to stabilize the frame.
05 · BALANCE
This is ultimately a front-and-rear balance problem
The nose pads and rear temple fitting do not work independently.
Stable front support plus appropriate side and rear restraint is what keeps the frame in position.
Tightening the back of a forward-sliding frame can hide the actual cause. Check front alignment, nose-pad contact, and frame width first, then refine temple and behind-ear support. If the front does not fit, using strong rear tension can simply add pressure at both the nose and ears.

GLANOS FITTING CHECK
GLANOS fitting check order
- Front
Check front alignment. - Nose pads
Check stable pad position and angle. - Width
Check necessary side support. - Temple bend
Check sufficient but not excessive rear support.
CAUTION
Do not simply narrow the nose pads because the frame shifts forward
Narrowing the pads can increase grip but also create nose pain and marks. The cause may instead be temple spread or a front-heavy balance, so check the full fitting sequence.
