Spec Check
Shield verificationglasses safety side shields
Use this Spec Check page to resolve open choices on glasses safety side shields fit, material and standard markings on accompanying frames before you accept an alternative factory offer. Check frame size, lens specification when the brief includes lenses, and standard markings on the quoted eyewear model—not on the shield accessory alone. Use one line per model. Mixed families belong on separate requests.

Do not mix side shields for glasses models on one unit price
| Check | Why it changes the quote |
|---|---|
| Frame fit | Lens width and temple length must accept the quoted shield |
| Shield form | Clip-on, permanent temple or integrated sunglass shield changes tooling |
| Safety mark | Z87 or similar belongs only to the named eyewear model sheet |
Before accepting an alternative, verify whether the substitute changes frame compatibility, shield opacity, hinge type or coating. A cheaper reply that swaps a clear safety clip-on for tinted sunglasses with side shields is not the same glasses safety side shields 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 eyewear model sheet states them; they do not transfer to a clip-on shield SKU automatically.
Selection checks that change the comparable quote
| Check | Buyer confirms | Why it matters |
|---|---|---|
| Frame size fit | Millimetre values on the sample | A one-size claim is not the same offer as marked sizes |
| Shield layout | Clip-on, permanent or integrated | Layout swaps change fit even when colour matches |
| Coating / anti-fog | Included or excluded | Silent omissions break landed-cost comparisons |
| Frame marking | Only if the named eyewear sheet states it | Shield quotes stay separate from full safety eyewear lines |
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.
Technical trade-offs on glasses safety side shields
Marked size
Lens width, bridge and temple length can be checked on the sample so the quoted glasses safety side shields fit the same frame family. Record millimetre values before accepting a cheaper substitute.
One-size claim
Only acceptable if the buyer agrees the fit range is unspecified. Treat that choice as an open item on the brief, not as proof that two factories quoted the same geometry.
Polycarbonate or acetate shield material, temple length clearance and anti-reflective coating on accompanying lenses stay written as included or excluded. Sample approval before bulk quantity remains the buyer's gate; this desk does not run a factory test lab.
