Explore our flagship OEM/ODM unisex optical frames engineered with Japanese grade-5 titanium, bio-based cellulose acetate, and lab-tested ergonomic balance. Glazing-ready, dimensionally certified, and optimized for global retail reorders.
Navigating technical ergonomics, non-binary facial geometry, and the convergence of medical optics with high-fashion industrial design.
In the contemporary B2B eyewear market, the distinction between menswear and womenswear optical collections has shifted from rigid taxonomic bifurcation to fluid, geometry-driven engineering. Contemporary procurement heads, regional distributors, and boutique optical directors increasingly prioritize unisex optical frames—not as a stylistic compromise, but as an advanced engineering solution designed to maximize shop-floor sell-through, reduce shelf inventory overhead, and satisfy an international consumer base that evaluates eyewear based on pantoscopic tilt, bridge seating, temple spring balance, and material authenticity.
As an ISO 9001 and ISO 12870 compliant optical manufacturing facility, our factory operates at the exact intersection of ophthalmological precision and artisanal tactile refinement. Producing unisex eyewear requires nuanced mathematical considerations that diverge sharply from traditional mono-gender sizing. While conventional male frames historically favored 54mm–58mm eye sizes with wide 18mm–22mm bridges, and female frames catered to 48mm–51mm eye sizes with narrow nasal saddles, modern unisex frames are crafted around unified anthropometric clusters. By leveraging parametric CAD modeling, adjustable pad-arm metallurgy, and anatomical keyhole bridge curves, our OEM/ODM production lines yield frames that sit flawlessly across diverse facial bridge profiles—including Caucasian high-nasal bridges and East Asian flatter nasal structures—without inducing temporal pressure or lateral slippage.
Unisex bridge geometry must accommodate variable pupillary distances (PD 58mm to 68mm) without causing optical decentration or excessive nasal crest pinching. Our CNC-milled acetate keyholes and micro-welded titanium bridges distribute frame mass evenly along the nasal dorsum.
We source raw plant-derived cellulose flake acetates free from phthalate plasticizers. Aged in environmental control chambers for up to 90 days to eliminate internal thermal stresses, preventing post-glazing frame warping or spontaneous temple twist.
Every rim groove is cut with a precise 110° to 120° V-profile, maintaining consistent 0.5mm edge depths. This guarantees high-index (1.67, 1.74) single-vision and freeform progressive lenses snap into place with zero optical ring birefringence.

Our material selection process is governed by a strict non-negotiable protocol. While budget wholesale suppliers rely heavily on recycled secondary acetate or low-grade zinc-alloy die castings, our manufacturing lines enforce pristine raw bar stock and sheet inputs. Secondary acetates suffer from volatile solvent evaporation over shelf time, causing frames to turn brittle, lose rim tension, and eject prescription lenses when exposed to temperature gradients. By contrast, our curated cellulose acetate slabs undergo strict stabilization cycles at 45°C and 60% relative humidity before precision 5-axis CNC machining, ensuring that each eyewear piece maintains its geometry through years of optician handling and daily wear.
Strategic foresight for product directors, optical chain merchandising executives, and venture-backed eyewear founders.
Global optical retail data reveals an accelerated departure from overt temple logos. Discerning end-users demand understated elegance characterized by internal laser etching, hand-chamfered bevels, and subtle rivets. B2B buyers must prioritize frame silhouettes that capture attention through silhouette equilibrium and tactile depth rather than ostentatious branding.
The industry benchmark now requires offering core frames in tandem configurations: an Rx-ready clear demo optical version alongside an identical silhouette fitted with UV400 Category-3 nylon sun lenses. This merchandising dynamic enables retailers to display a cohesive brand story across optical and sunglass display boards while streamlining tooling investment.
European and North American regulatory pressures (such as the EU Corporate Sustainability Due Diligence Directive) require wholesale importers to demonstrate verifiable supply chain footprints. Procurement trends favor factories capable of providing certified bio-based acetates, closed-loop water filtration during tumbling, and recycled titanium smelting credentials.
In addition to material sustainability, the rapid rise of remote telemedicine optometry and virtual try-on (VTO) algorithms has altered how wholesale frames are engineered. Unisex frames must now possess photogrammetrically distinct landmarks—sharp rim transitions, controlled surface reflectivity, and standardized facial indexing points—to render accurately within Augmented Reality (AR) try-on SDKs. Our ODM design department delivers production-matched 3D CAD files (.STP, .OBJ, .GLTF) alongside physical shipments, enabling your digital marketing and e-commerce teams to deploy photorealistic virtual try-on experiences well before cargo touches domestic distribution hubs.
An inside look at our industrialized fabrication protocol, detailing each verification gate in custom unisex frame production.
Transforming client mood boards, technical sketches, or physical reference samples into micron-accurate 2D technical drawings and 3D parametric models. Functional SLA/SLS resin prototypes are produced within 72 hours for ergonomic trial fitting.
Hardened steel stamping dies and multi-axis CNC path files are cut in-house. Acetate slabs are contour-cut under continuous coolant flow, while titanium components are cold-stamped under 300-ton hydraulic presses to maximize crystalline metal density.
Raw acetate front pieces and temples undergo a 4-stage, 72-hour automated polishing cycle inside rotary hexagonal barrels loaded with selected Italian walnut shells, pumice abrasives, and organic vegetable oil pastes, yielding silky smooth bevels.
Master optical technicians hand-pin hinges, insert embedded filigree core wires, mount silicon-air nose pads, and calibrate pantoscopic tilt to a standard 8-degree angle. Every frame undergoes four-point horizontal alignment on calibrated granite slabs.
A crucial quality indicator for high-end optical buyers is the integrity of the hinge mechanism. Budget manufacturers typically press heat-staked hinges directly into warm acetate—a shortcut that inevitably results in loose temples and wobbling arms after minor adjustments. In our factory, all premium acetate lines feature genuine pinned hinges secured through rivets or CNC-counterbored anchoring plates with thread-locking micro-screws. For titanium frames, we utilize vacuum brazing techniques in inert argon environments, eliminating weld oxidation and securing a microscopic joint bond that resists over 250 Newtons of torsional strain.
Every production run is certified against rigorous global optical standards before leaving our logistics hub.
Under ISO 12870:2016 clause 4.8, our pneumatic cyclical testers compress and expand the eyewire 500 times at 40 cycles per minute. The frame must exhibit zero cracking, no plastic deformation exceeding 1.5mm, and retain secure lens groove clamping pressure.
Frames undergo 96-hour continuous exposure to synthetic perspiration solutions buffered at pH 4.7 and 55°C (DIN EN ISO 12870). Metal platings and acetate luster must demonstrate zero blistering, corrosion, discoloration, or delamination.
All electroplated and alloy components touching the wearer's dermis are certified to release less than 0.5 µg/cm²/week of nickel ions. This standard protects private-label brands from European customs seizures and consumer dermatological recalls.
