PC (Polycarbonate) Sunglasses Manufacturer

Impact-Resistant Frames and Lenses Engineered for Safety, Sport, and Promotional Programs

Polycarbonate is the standard material wherever eyewear needs to meet a genuine impact-resistance standard — built for repeatable geometry, dependable structure, and stable supply across scalable programs.

What PC (Polycarbonate) Sunglasses Mean

Polycarbonate is one of the only materials in eyewear that functions as both a frame material and a lens material. As a frame, PC is injection-molded — heated resin injected into a steel mold — competing with TR90 and other injection plastics. As a lens, PC competes with CR-39, TAC, and glass, valued specifically for its near-unbreakable resistance to shattering.

If your program needs eyewear that reliably meets a genuine impact-resistance standard — safety glasses, sports eyewear, kids' eyewear, or high-volume promotional product — PC is the material built for that requirement.

For frame-only applications prioritizing flex-and-recover comfort over lens-grade impact resistance, TR90 may be a better fit — we'll advise honestly on which material suits your specific program.

PC Frame vs PC Lens — Why the Distinction Matters

Most content treats "PC sunglasses" as a single category. It isn't — the relevant performance properties differ depending on which application is intended, and your brief should specify which one (or both) you need.

PC as a Frame Material Structure

Injection-molded into the front frame and temples, competing with TR90 and nylon for the same structural role. Tolerates flex and twisting well — a frame that gets sat on or bent during active use has a real chance of returning toward its original shape rather than cracking.

Relevant properties: flexibility, impact resistance, hinge durability

PC as a Lens Material Optics

Molded into the optical element itself, competing with CR-39, TAC, and glass. Up to 10× more impact-resistant than standard plastic lenses, inherently UV-blocking, and the standard choice wherever a shattered lens presents a genuine injury risk.

Relevant properties: optical clarity, light transmission, coating performance

A brief that simply says "PC sunglasses" leaves this distinction for the manufacturer to assume. Specify frame, lens, or both — read our full breakdown in What Is PC (Polycarbonate)? The Material Behind Safety and Sport Eyewear.

Why Brands Choose Polycarbonate

Highest impact resistance

Roughly 10× more impact-resistant than acetate — the property behind PC's role in safety, sport, and kids' eyewear.

Inherent UV protection

Polycarbonate naturally blocks UV radiation without requiring an additional applied coating for that specific function.

Cost-efficient at volume

The lowest-cost injection material at promotional volume, with repeatable geometry across production runs.

Key Advantages for Safety and Sport Programs

Drop-Ball Test Performance

When properly manufactured, PC frames reliably meet or exceed FDA drop-ball impact testing and similar global standards.

Lightweight Structure

Lighter than metal and most acetate, supporting all-day comfort for active and youth wearers.

Repeatable Shape Control

Mold-controlled geometry stays consistent across batches and seasonal runs.

Lens + Frame in One Material

One of the few materials suitable for both frame and lens, simplifying sourcing for impact-rated product lines.

PC vs TR90: How They're Actually Different

Both are injection-molded plastics in a similar cost tier, but they are chemically distinct and suited to different parts of an eyewear line.

PC's Strength Is Impact Resistance and Lens-Grade Application — TR90's Is Flex-and-Return Comfort

Property PC TR90
Chemical family Polycarbonate Nylon-12 (Grilamid)
Primary strength Impact resistance Flexibility with memory return
Lens use Common, standard material Not typically used as a lens material
Frame flex behavior Flexes and resists fracture Flexes further, returns to shape
Best for Safety-certified eyewear, lens + frame programs Sport, kids', fashion frames where all-day flex matters most

PC is generally the more complete specification when the product needs to function as genuine impact-rated safety or sport eyewear — both lens and frame — since TR90 is not standardly used as a lens material. For frame-only programs where all-day comfort and bend-and-return behavior matter most, see our dedicated TR90 sunglasses page and our detailed PC vs TR90 comparison guide.

Design Possibilities with PC Molding

PC's flexibility supports curved, wraparound, and shield profiles that more rigid materials can't achieve as easily — useful for sport and safety-positioned silhouettes.

Curved and wraparound profiles for sport coverage

Clean geometry suitable for classic and modern silhouettes

Controlled thickness transitions for structured looks

Mirror, gradient, and polarized lens combinations

Engineering-First Tooling for Stable Long-Term Production

In PC injection programs, tooling and structural planning determine how consistent production will be. We plan geometry, wall thickness, and assembly points to support repeatable outcomes — and impact performance — over time.

What Safety Standards Should PC Sunglasses Meet?

PC is widely recognized, tested, and accepted across major compliance frameworks for safety and sport eyewear. In the US, the FDA requires sunglasses to pass a drop-ball impact test simulating blunt-force impact — PC reliably meets or exceeds this when properly manufactured.

For sport and protective eyewear specifically, ANSI Z87.1 is the relevant US standard, with equivalent frameworks in other major markets. We'd rather confirm exactly what your target market requires than assume PC alone guarantees compliance — material choice and proper manufacturing both matter.

All PC frames can be tested using the FDA drop-ball method with test reports provided upon request

ANSI Z87.1 and equivalent regional standards apply specifically to sport and protective-positioned eyewear, not all sunglasses

If safety certification matters to your brand, confirm testing documentation with us before bulk production — not after

What We're Direct About

FDA drop-ball test Required for all US-market sunglasses; PC meets it when properly made
ANSI Z87.1 Applies to sport/protective eyewear specifically — confirm relevance to your line
Optical clarity Good, but lower Abbe value than CR-39 — chosen for impact resistance, not max clarity
Scratch resistance Lower uncoated — standard hard coating addresses this on all PC lenses we produce

FAQ

Typical MOQ is 1,000–1,200 pieces per model, plus 300 pieces per colorway. Mold (tooling) cost runs $1,470–$4,500 depending on frame complexity and cavity count. Sampling takes 5–10 working days once the mold is confirmed, with bulk production following in 35–55 working days depending on order volume.

No. Polycarbonate and TR90 are chemically different materials. TR90 is a branded nylon-12 formulation (Grilamid TR90), while polycarbonate is a distinct polymer family. Both are injection-molded and share some performance similarities — light weight and flexibility — but PC's defining strength is impact resistance and lens-grade application, while TR90's strength is flex-and-return comfort in frame-only construction. See our PC vs TR90 comparison for full detail, or visit our dedicated TR90 page.

Yes — this is one of the few eyewear materials that functions in both roles. As a frame material, PC competes with TR90 and nylon. As a lens material, PC competes with CR-39, TAC, and glass. Your brief should specify which application — or both — is intended, since the relevant performance properties differ between the two uses.

For the US market, the FDA requires all sunglasses to pass a drop-ball impact test. For sport and protective eyewear specifically, ANSI Z87.1 is the relevant standard, with equivalent frameworks in other major markets. PC reliably meets or exceeds these when properly manufactured — we provide test reports on request and recommend confirming which standard applies to your specific product positioning before bulk production.

The same molecular flexibility that gives PC its impact resistance also makes it softer than glass or CR-39, which makes it more prone to surface scratching. This is addressed with a hard scratch-resistant coating applied after molding — standard practice on every PC lens we produce, and virtually all commercially sold PC lenses.

Yes. Series planning is a common use case for PC injection programs — one mold investment can support a multi-color, multi-SKU release calendar. Color is typically set per production run rather than mixed freely within a single batch, so plan your colorway split before tooling is finalized.
