Top 10 Polarized Sunglasses Wholesale Manufacturers & Exporter

Our manufacturing facilities employ a proprietary thermal-laminate bonding sequence with medical-grade PVA (Polyvinyl Alcohol) polarizing films encapsulated between optical-grade cellulose triacetate shields. We conduct accelerated boiling tests (100°C for 2 hours) and autoclave environmental exposure checks (60°C at 95% relative humidity for 72 hours). This protocol guarantees that our polarized lenses maintain structural adhesion and eliminate film separation or bubbling in tropical and marine environments.

For catalog SKUs in ready stock (including PC, TR90, and Metal lines), our MOQ starts at 50 to 100 units per colorway with laser-etched custom temple logos. For custom pantone-matched acetate frames or ground-up bespoke tooling (OEM/ODM mold creation), our typical production run starts at 300 to 600 units per style, allowing brands to test new market segments with minimal capital exposure.

Yes. Every production run is tested using spectrophotometric systems to confirm UV400 performance, blocking 100% of UVA and UVB spectrums up to 400nm. We verify transmittances (Category 2, 3, or 4), refractive power balances, optical prism deviation, and drop-ball mechanical impact resistance (FDA 21 CFR 801.410). Complete laboratory test certificates from independent institutions (SGS, Intertek, or TUV) are furnished on request with each shipment.

Yes. Our acetate and TR90 collections, along with our premium Monel and stainless-steel chassis, are engineered with standard 4.5-base to 6-base lens grooves and balanced pantoscopic tilt. This ensures that in-store opticians and finishing labs can cold-insert or heat-mount single-vision, progressive, and prescription polarized lenses without distorting frame geometry or stressing bridge solder joints.

We provide full commercial documentation including certified Commercial Invoices, Packing Lists with volumetric metrics, Certificates of Origin (Form A, EUR.1, or RCEP), Drop Ball Impact Test declarations, and airway/bill of lading documentation. We execute under Incoterms EXW, FOB (Shanghai, Ningbo, or Nhava Sheva Mumbai), CIF, and DDP to handle door-to-door fulfillment through DHL, FedEx, and sea freight forwarders.
