Seamlessly bridging optical prescription frames with sunwear functionality. Produced using proprietary neodymium magnet anchoring, ultra-resilient TR90, and triacetate cellulose (TAC) polarized optics.
Carrying forward three generations of eyewear manufacturing from Lozzo di Cadore, Italy. Complete vertical integration from initial CAD blueprints to automated polarization stress testing.
Full control under one roof. Our Italian heritage centers around proprietary mold-making and micro-hinge design, guaranteeing that the production lot matches client-approved golden samples down to 0.02mm tolerances.
Specialized processing in Mazzucchelli Cellulose Acetate, surgical-grade Swedish stainless steel, titanium alloys, and ultra-flexible Swiss Grilamid TR90 injection systems.
Trusted by global optical chains and boutique private labels across 90+ countries. Every custom magnetic mounting mechanism, bespoke rim geometry, and brand livery is protected under enforceable NDAs.
Modern clip-on sunglasses have evolved far beyond basic wire clips. In contemporary B2B optical distribution, buyers require advanced magnetic locking mechanisms, zero chromatic aberration, and seamless co-planar alignment with prescription lenses.
Our manufacturing workflow incorporates high-grade N52 Neodymium rare-earth magnets seamlessly integrated into the temporal lug cavities. These are coated with triple-layer nickel-copper-nickel galvanic finishes to completely eliminate atmospheric oxidation and corrosion caused by human perspiration.

Whether configuring our signature 5-in-1 Magnetic Clip-On sets or precision FL-41 therapeutic migraine filters, each optical unit undergoes automated spectrometry to ensure 100% UV400 blocking up to 400nm wavelengths.
Key intelligence for enterprise category managers, optical chains, and brand directors preparing procurement roadmaps over the coming half-decade.
Global regulatory bodies like the EU Green Deal are driving requirements for circular materials. Production shifts from fossil-based propionates toward ISCC-certified Bio-Acetate and bio-based TR90 synthesized from sustainably farmed castor seeds.
Clip-on products are moving beyond general solar protection into active therapeutic medical eyewear. Our dedicated cleanroom lines produce clips with precise spectrophotometric cutoff curves, including FL-41 rose tints for chronic migraine and photophobia management.
The marketplace increasingly rejects conspicuous top clips. The modern standard demands sub-surface neodymium embedding, where the magnetic core is encapsulated inside the inner rim wall. This leaves the optical frame visually indistinguishable from non-clip luxury frames.
Clear, direct answers regarding custom tooling, supply chain logistics, and quality assurance.
For existing catalog models with custom laser branding and custom lens tints, our base MOQ begins at 300 units per colorway. Fully customized private-label molds requiring dedicated injection tooling or bespoke frame geometries typically carry an entry MOQ of 1,200 units across up to 3 SKUs.
Our engineering team calculates a calibrated 0.65mm co-axial air gap between the concave back curve of the sun lens and the convex surface of the optical base curve. High-contact stress points are fitted with medical-grade silicone sleeves or micro-flocked buffers to prevent abrasive friction during daily use.
All finished optical assemblies comply fully with EN ISO 12312-1:2013/A1:2015 (Europe), ANSI Z80.3-2018 (United States), and AS/NZS 1067.1:2016 (Australia/New Zealand). Declarations of Conformity (DoC), FDA drop-ball impact test certificates, and RoHS analytical test sheets accompany every commercial export shipment.
Rapid rapid-prototyping via high-resolution SLA resin models takes 7–10 business days. Steel tooling fabrication and physical master sample sign-off typically require 35 days. Mass industrial production, secondary ultrasonic cleaning, final assembly, and 100% QA check runs are completed within 45–60 days depending on lot volume.
From initial design sketches and structural FEA analysis to full-volume mass manufacturing, our Cadore engineering facility delivers the precision and scale your enterprise demands.
