Perceived weight in plastic frames depends on acetate mass, lens size, bridge contact area, frame width and behind-ear support.
01 · ACETATE THICKNESS
A thick frame has material weight of its own
Acetate fronts and temples can be quite thick depending on the design.
A larger frame also contains more material and can weigh more.
A thick front combined with large lenses can also shift the center of mass forward.
02 · LENS SIZE
Large lenses add to total weight
As lens area increases, lens mass generally increases as well.
With higher prescriptions, finished thickness and weight depend on lens design, material and frame size.
For a large plastic frame, consider the actual lens requirements as well as the frame design.
03 · BRIDGE CONTACT
Is only a narrow part of the bridge carrying the load?
In plastic frames, the bridge transfers front load to the nose.
If the bridge does not contact broadly and instead loads a small edge, the glasses can feel much heavier than their actual mass suggests.
If nose pain accompanies the heavy feeling, check bridge contact first.
04 · FRAME WIDTH
Too-wide or too-narrow frames interfere with load sharing
A frame that is too wide can lose lateral stability and move forward, while a frame that is too narrow can compress the temples.
The bridge should support the front load stably while the temples control lateral movement without excessive pressure.
05 · EAR SUPPORT
Is the frame supported enough behind the ears?
A loose bend can let the frame move forward and concentrate more pressure at the bridge, while a bend that is too deep can create ear pain.
The bridge mainly supports the front load, while the temples and behind-ear fit stabilize front-to-back and side-to-side movement as needed.
SOLUTION GUIDE
Solutions at a glance
Check overall frame size and material volume.
Check lens size, material and thickness.
Check bridge contact area.
Check frame width and behind-ear support.
GLANOS FITTING CHECK
GLANOS fitting check order
- Front
Make sure the frame is straight. - Bridge
Check broad, stable contact on the nose. - Width
Check whether frame width matches the face. - Temple bend
Confirm only the necessary amount of rear support.
CAUTION
Do not solve weight by bending the temple ends too deeply
Trying to hold a front-heavy frame only behind the ears can create ear pain or temple pressure. If the frame itself is excessively large and heavy, choosing a different frame may be better than repeated fitting.
