Frame identity and lens safety require different evidence. Inspect the claim, preserve interventions and prepare an honest next transaction.
The five-part evidence system
Do not let one familiar detail carry the conclusion.
Frame
Geometry, acetate or metal, hinges, temples and finish
Marks
Temple text, size codes and logos read in context
Lenses
Prescription or UV claims supported by qualified optical testing
Interventions
Replacement lenses, hinge repair, adjustment and provenance
Repair-aware inspection
Three legitimate changes that still need an explanation.
Repair history is neither automatic proof nor automatic suspicion. The useful question is whether the current object and its records tell one disclosed story.
Replacement lenses
Legitimate new lenses may remove original marks or tint. Document provider and protection specification.
Heat-adjusted frame
Adjustment can change alignment and temple geometry without implying counterfeit origin.
Replaced hinge or temple
Mixed parts need accurate disclosure and may affect model comparison.
Preserve the evidence
Before cleaning, servicing or adjusting.
- 01Use an optical professional for lens performance or fit claims.
- 02Photograph model markings before adjustment or replacement.
- 03Avoid heat and household chemicals on acetate and coatings.
- 04Keep lens invoices and test specifications with the frame record.

Eyewear FAQ
Questions that protect the next decision.
Does a logo on the lens prove authenticity?
No. Marks can be copied and lenses can be replaced. Examine the frame identity separately.
Can PieceID verify UV protection?
No. UV protection is a performance claim requiring appropriate optical testing.
Are replacement lenses a red flag?
Not automatically. They should be documented because they change the current configuration.
Why do temple codes differ?
Size, region, production period and frame variant can differ; compare the exact claim.
