Fitting can improve many problems, but frame size, bridge design, and excessive front or lens weight can create limits that adjustment alone cannot remove.
01 · ADJUSTABLE
Some variables can be changed through fitting
Metal frames allow relatively fine adjustment of nose-pad position and angle, temple spread and rear bends.
Plastic frames can also be adjusted at the temples and rear bends depending on material and construction.
Mild tilt, looseness and pressure often improve with fitting.
02 · FRAME SIZE
Fitting cannot completely change the actual frame size
Forcing a frame that is far too narrow to stay widely spread can place continuous stress on the hinges and front.
Forcing an overly large frame much narrower can reduce stability and distort its shape.
When the size mismatch is large, frame selection is the more fundamental issue.
03 · BRIDGE DESIGN
Bridge design can also be a structural limit
If a plastic bridge is substantially mismatched to the nose, temple fitting alone may not solve the problem.
Adhesive pads or custom nose-pad modifications can help selected frames, but not every frame is suitable and structure, material and machining allowance need to be considered.
04 · LENS WEIGHT
Lens and front weight can also limit fitting
Very large or thick lenses, or a heavy frame front, do not become lighter simply by tightening the temples.
A high prescription does not automatically mean high weight, so lens size, material, design, thickness and frame construction should be considered together.
05 · RESELECT
Choosing a different frame can be the better solution
The purpose of fitting is not to force every frame onto every face.
When the required correction exceeds the safe or practical adjustment range, choosing a frame better matched to the face and lens requirements can be more stable.
SOLUTION GUIDE
Key points at a glance
Mild tilt, nose-pad angle, temple pressure, rear bends and minor looseness from use.
Large mismatch in overall width or a bridge that is fundamentally unsuitable.
Review lens size, material, thickness and frame selection.
Reassess structural limits and overall frame suitability.
GLANOS FITTING CHECK
GLANOS fitting check order
- Front
Check the frame reference state. - Nose pads / bridge
Determine the realistic adjustment range at the nose. - Width
Compare total frame width with face width. - Temple bend
Check whether the rear fit is compensating for a front problem.
CAUTION
Repeating fitting does not solve every problem
Continually forcing a frame beyond its adjustment range can add unnecessary stress to the hinges and front. Choosing a more suitable frame is sometimes part of good fitting judgment.
