Define the claim
A polarized label describes a filter intended to reduce certain reflected glare. It does not by itself state UV performance, category, transmission, color accuracy or regulatory compliance.
Request evidence appropriate to the sale
Ask what specification, supplier declaration or test evidence supports the claim and whether it applies to the exact model/colorway being ordered.
Compare the retail use case
Polarized products may be relevant to driving, water or outdoor assortments, while non-polarized fashion tints may serve different styling and price needs. Avoid universal benefit claims.
Keep catalogue and tested facts separate
A site collection should include polarized products only when the supplier record states it. Stronger performance claims require stronger evidence.
Quick answers
Does polarized automatically mean UV400?
No. Polarization and UV protection are different claims and require their own supported specifications.
Can product photos prove polarization?
No. Request appropriate specification or test evidence for the exact product.
How does KUANGTU build its polarized collection?
The collection is limited to product records whose supplier-provided lens description explicitly states polarization.
