CR-39 vs Polycarbonate: A Technical Lens Selection Guide for OEM Eyewear Brands

CR-39 and polycarbonate are the two most widely used lens materials in OEM sunglasses and optical eyewear production. They are not interchangeable. Each has a specific optical profile, impact performance, and processing requirement that maps to a defined set of product categories. Selecting the wrong material for the wrong application does not produce a slightly inferior product — it produces a structurally mismatched one. This guide provides the technical basis for making that decision correctly.

TR90 vs Carbon Fiber vs Titanium Sports Sunglasses | OEM Frame Guide

If you're sourcing custom sports sunglasses—whether for a cycling brand, an outdoor retail chain, or a private-label fitness line—frame material is one of the first decisions that shapes everything downstream: price point, target audience, tooling complexity, and the story your product tells on shelf. As a lens manufacturer working with OEM and ODM partners worldwide, we're often asked the same question: which material is right for my product? This guide breaks it down clearly so you can walk into your next sourcing conversation with confidence.

Frequently Asked Questions About Eyewear Manufacturing

Everything You Need to Know About Our Custom Manufacturing Process and Global Partnership.

Can't find your answer?

What is your Minimum Order Quantity (MOQ) for custom private label sunglasses?

We offer flexible solutions to support brands at different stages. While standard mass production typically starts at 300-600 units, we provide private label sunglasses with no minimum options for selected stock models to help startups test the market rapidly.

How long does the prototyping and mass production process take?

As a high-efficiency eyewear factory, we provide fast prototype sampling within 7-14 days. Once the sample is approved, standard mass production typically takes 30-45 days, depending on the complexity of the design and material requirements (e.g., Acetate vs. Titanium).

Does Karuson provide certified RX (Prescription) lens customization?

Yes. We specialize in precision optical engineering. Our facility includes a professional RX lab capable of customizing Myopia, Hyperopia, Progressive, and Polarized RX lenses that meet international optical safety standards.

Are your products compliant with global import regulations like CE and FDA?

Absolutely. Every pair of glasses manufactured by Karuson undergoes strict QC and is fully certified for CE, FDA, and ISO 9001. We provide all necessary documentation to ensure smooth customs clearance in Europe, North America, and other global markets.

Can you provide one-stop branding and packaging solutions?

Yes, we offer a complete retail-ready ecosystem. Beyond frame manufacturing, we provide bespoke branding (laser/printing) and full packaging sets, including custom hard cases, microfiber cloths, and luxury gift boxes tailored to your brand identity.
