Why KARUSON Polarized Lenses Matter to KARUSON

Polarized lenses reduce glare, enhance contrast, and improve visual comfort in bright, reflective environments. For retailers and brands, offering polarized options raises perceived product value while reducing returns related to visual dissatisfaction. KARUSON approaches lens development with a design-first philosophy: matching tint profiles and polarization strength to real-world use cases such as driving, fishing, skiing, and everyday urban wear.

Targeted performance profiles: high-contrast amber for fishing, neutral gray for accurate color perception, brown for depth enhancement.
Material choices: lightweight polycarbonate for impact resistance, CR-39 for optical clarity, and high-index options for slimmer lens profiles.
Coatings and enhancements: anti-reflective, hydrophobic, scratch-resistant, and oleophobic finishes to extend in-field durability.

FAQ

What is the minimum order quantity (MOQ) for polarized lenses when ordering in bulk?

MOQ varies by lens type, coating complexity, and customization. KARUSON offers flexible MOQ tiers to support new brands and larger distributors. Simple standard polarized lens batches often start with modest MOQs, while fully customized lens+frame assemblies require higher minimums. For exact MOQ guidance based on your specification, contact nicole@karusonco.com with your lens material, tint, polarization level, and projected annual volumes.

How long does it take to produce a custom polarized lens order from prototype to shipment?

Typical timelines depend on complexity. Rapid prototyping for lens samples can be completed within days to two weeks. Once samples are approved, production lead time for bulk polarized lenses generally ranges from 4 to 10 weeks depending on order size and finishing processes. KARUSON’s two-factory setup helps compress lead times for larger or staggered deliveries; provide your required delivery window to get a precise schedule.

What customization options are available for polarized lenses and associated eyewear?

KARUSON provides end-to-end customization: polarization strength and direction, tint color and density, lens materials (polycarbonate, CR-39, high-index), AR and hydrophobic coatings, and bespoke laser engraving for logos. For full eyewear solutions KARUSON also offers custom frames, hinges, temple designs, and packaging tailored to brand positioning. All options are supported by in-house prototyping and tooling services.

How does KARUSON ensure the optical quality and safety of polarized lenses supplied in bulk?

Quality control is performed at every production stage. KARUSON tests polarization efficiency, UV protection, impact resistance where applicable, and maintains optical clarity standards. Incoming raw materials undergo inspection and traceability checks. Final batches include visual and instrumented optical inspections, and KARUSON can supply testing certificates and compliance documentation for major markets in Europe and the Americas upon request.

Can you ship samples and small pilot runs internationally, and what are the shipping options?

Yes. KARUSON supports international sample shipments and small pilot runs to validate designs and market performance. Shipping options include air freight for rapid delivery and sea freight for cost efficiency on larger shipments. KARUSON can coordinate DAP, FOB, or CIF terms and assist with customs documentation.
