Record the exact assembly
Ask for a model identifier, drawing revision and complete component list. Tie the physical sample label to the same record.

S2 / Concept dossier
A continuous shield study that keeps lens and component assumptions visible.
A continuous lens surface sits beneath a restrained brow. The single-shield concept calls for a different evidence set from the two-lens studies.
Ask for the complete assembly definition before discussing a shield change. The concept image cannot establish edge retention, lens properties or replacement method.
Dimensions above are invented illustrative references. They are not measured from the artwork, not toleranced drawings, and not fit or lens-processing advice.
Interface focus
No hinge-cover mapping is provided for this study. A similar-looking cover from another model must stay outside the reference list.
Nose saddle and temple-tip pair may be discussed as reference candidates. Hinge cover remains unmapped.
Read the evidence boundaryThe dossier has no supplier facts to substitute for the documents below.
Ask for a model identifier, drawing revision and complete component list. Tie the physical sample label to the same record.
Ask the real supplier to identify applicable requirements for the intended use and market. This demo makes no optical, impact, retention or protective claim.
Keep fit observations separate from approval. Record the open issue, who will answer it and what evidence would close it.
