Spec Check
polarized polycarbonate lenses
Quotes are comparable only when the frame size or lens design matches. Use this Spec Check page to resolve open choices on polarized polycarbonate lenses, frame size, lens specification and standard markings before you accept an alternative factory offer. We are an independent sourcing desk, not the lens laboratory.
- Name the polarized polycarbonate lenses form being priced.
- State millimetre sizes, lens colour and whether polarization is included.
- List pair counts by model and the US ship-to code.
Not included unless the reply writes them in
- Coatings beyond the stated polarization film
- Case, cloth or display
- Freight and duty
Safety glasses with polycarbonate lenses: measurements that keep quotes comparable
-
1. Same model
Each quote names the polarized polycarbonate lenses form being priced. A catalogue photo without lens width, bridge and temple in millimetres is not a comparable line.
-
2. Same exclusions
Coatings, case and freight are in or out. Polarization must be written into the pair price or stated as excluded; silent omissions break landed-cost comparisons.
Before accepting an alternative, verify whether the substitute changes base curve, temple length or the polarization path. A cheaper reply that swaps a non-polarized blank for a polarized film is not the same polarized polycarbonate lenses line. Ask for the documents that cover the quoted item rather than a generic factory brochure. Markings such as Z87 apply only when the named model sheet states them.
Selection checks that change the comparable quote
| Check | Buyer confirms | Why it matters |
|---|---|---|
| Lens width / bridge / temple | Millimetre values on the sample | A one-size claim is not the same offer as marked sizes |
| Polarization | Included, excluded or undecided | Film routes change cost even when the outer blank matches |
| Coatings | Hard coat or anti-reflective included or excluded | Silent omissions break landed-cost comparisons |
| Safety marking | When the named model sheet states it | Plano and prescription-adaptable lines stay separate |
These checks are procurement verification steps, not factory test certificates owned by this desk. Sample approval remains the buyer's decision before bulk quantity releases. Review inquiry options when the form is known.
