01 · METAL FRAME
Metal frames can be adjusted within limits
Nose-pad arms, temples and some parts of the front can be adjusted depending on the material and construction.
A severely folded area or a part that has been bent repeatedly needs closer inspection for fatigue, microcracking and fracture risk.
Metal frames can often be adjusted at pad arms, temples, bridges and selected front areas, but different metals and cross-sections tolerate different bending. Pure titanium, titanium alloys and stainless steels do not behave identically, and weld locations deserve special inspection before straightening.
02 · METAL FATIGUE
Straightening does not return the material to its original condition
Repeated bending can accumulate fatigue and increase the risk of small cracks.
Welds and thin components in particular should be checked carefully after repeated repair.
A frame that looks straight again is not necessarily materially identical to a new frame. Repeated plastic bending can accumulate work hardening, fatigue damage or microcracks depending on alloy and history, so repaired areas should be checked for renewed deformation and surface changes.
03 · ACETATE FRAME
Acetate can be adjusted with controlled professional heat
During professional fitting, only the area that needs adjustment is heated within a range appropriate for the material and structure.
The heating method must also consider the frame construction and lens condition; severely deformed or degraded acetate may not fully recover.
Acetate can be reshaped within limits using controlled heat, but shrinkage, cracking, whitening or severe distortion cannot always be returned to factory condition. Whole-frame heating with hot water or a household dryer is difficult to control and can move adjacent rim and bridge areas.
04 · CRACK
A crack is no longer just a fitting problem
If the bridge, rim or hinge area is cracked, forcing the frame back into shape can enlarge the damage.
A crack is not simply a fitting error. Cracks around bridge, rim or hinge occur in load-bearing areas, and forcing the frame back into shape can extend the fracture; structural damage should be assessed before fitting.
05 · REPEATED REPAIR
Repeatedly repaired frames require more caution
If the same area keeps going out of shape, check frame sizing, use habits and structural causes as well.
If the same area bends repeatedly, look beyond accidental handling. Frame width, asymmetric ear position, hinge condition or bridge weakness may be recreating the problem, so repair should aim to reduce the recurrence condition as well as restore shape.
SOLUTION GUIDE
When evaluating a deformed frame
Alignment and fitting may improve it.
Adjustment may be possible depending on material and structure.
Check fatigue, cracks and fracture risk.
Professional repair or replacement assessment comes before ordinary fitting.
GLANOS LENS CHECK
Restoring shape and achieving a good fit are different tasks
After repair, fit should still be checked in order: front → nose pads/bridge → width → temple bend.
CAUTION
Do not force a bent frame straight or heat acetate with hot water at home
A small deformation can become a larger failure.

There is a reason glasses feel uncomfortable.
