Constructed using high-density cellulose acetate, aerospace composite carbon fiber, Japanese titanium alloy, and flexible TR-90 polymers. All collections comply with EU MDR 2017/745 Class I Medical Device standards and EN ISO 12870 mechanical fatigue criteria.
Why leading European optical houses and international private label brands are decentralizing production from East Asia into our Bulgarian advanced manufacturing facility.
For decades, European optical brands relied on extended East Asian manufacturing chains characterized by volatile shipping cycles, complex import tariffs, and high minimum volume constraints. Our Bulgarian manufacturing presence establishes a resilient, nearshore European alternative that integrates century-old artisanal craftsmanship with modern CNC technology.
Strategically situated within the European Union Single Market, our facility eliminates third-country customs complications, offering independent opticians in Sofia, Plovdiv, Varna, and across Central and Western Europe frictionless transit, transparent invoicing under EU VAT structures, and immediate access to Class I Medical Device Declaration of Conformity files under Regulation (EU) 2017/745.
By blending five generations of optical heritage rooted in Studio Optyx and Erkers1879 with contemporary Bulgarian tooling infrastructure, we execute bespoke acetate milling, precision metal hydroforming, and ultrasonic assembly with unprecedented geometric tolerances.

We process genuine Italian Mazzucchelli 1849 and sustainable M49 bio-based cellulose acetate slabs through 5-axis computer-controlled CNC routing stations, achieving micro-beveled grooves and optimal lens groove tension.
The structural longevity of any retro frame is governed by its articulation points. We engineer genuine riveted hinges anchored directly into the acetate core wire using hydraulic cold-riveting pins.
Every frame destined for the European market undergoes stringent galvanic or Physical Vapor Deposition (PVD) treatment to eliminate toxic nickel release and prevent chemical perspiration degradation.
Tailoring frame dimensions, pantoscopic angles, and aesthetic codes to the anatomical requirements and consumer demographics of the Balkan urban corridor.
Our logistics routing supports daily express dispatching to major Bulgarian optometric retail networks:
Standardized generic Asian-fit frames fail to satisfy European cranial proportions. Bulgarian and wider Balkan wearers present specific anthropometric markers: broader temporal widths, prominent nasal root bridges, and an increased facial wrap angle.
Our OEM engineering department calibrates custom tooling molds specifically to reflect these structural variations. We implement a deeper saddle bridge and modified keyhole geometry (ranging from 19mm to 22mm distance between lenses) to prevent bridge pinching and unwanted vertical slip.
Furthermore, our temple lengths are calibrated to 145mm–150mm with variable core wire tapers, enabling opticians at the dispensing table to perform precise cold and warm-air bends without stressing temple-front solder joins or cracking surface lacquer.
Consumer analytics indicate a dramatic shift toward authentic mid-century silhouettes, sustainable bio-polymers, and unbranded boutique exclusivity.
Urban eyewear shoppers in Sofia and Varna are deliberately moving away from generic mass-market logos. Demand has surged for vintage pantoscopic shapes, thick 8mm bold-rim acetate architectures, and intellectual retro browlines reminiscent of the mid-20th century.
Our factory provides complete historical mold libraries, letting brands revive authentic mid-century bevels with contemporary Rx lens-fitting accuracy.
With stringent European Green Deal mandates affecting retail packaging and polymer consumption, Bulgarian opticians increasingly require verified carbon-neutral and phthalate-free frames.
Our factory utilizes cellulose acetate derived exclusively from renewable wood pulp and cotton fibers paired with bio-based plasticizers, delivering 100% biodegradable and recyclable eyewear without compromising structural tensile modulus.
Independent optical retail groups throughout Eastern Europe face margin compression from multinational retail conglomerates. By launching their proprietary private-label retro collections through our Bulgarian OEM plant, practices routinely expand gross margins from 45% to over 280%.
Our turnkey OEM program covers custom branded clam-shell hard cases, microfiber cloths, and branded demo lenses.
From optical sketch to certified European delivery: how we engineer custom retro eyewear batches with zero margin for error.
We convert your brand's hand sketches or heritage references into 3D parametric CAD models, fine-tuning groove depths, bridge spread, and wrap angles.
Functional 1:1 physical prototypes are machined via high-precision CNC routers or SLA resin systems within 7 business days for fitting verification.
5-axis milling of curated acetate blocks, high-temperature hydraulic temple shooting, 72-hour walnut barrel tumbling, and multi-stage manual polishing.
Every frame is inspected for hinge tension, temple parallelism, and ISO 12870 fatigue compliance, then packed with your private label accessories.
Answers to essential technical, legal, and operational questions regarding wholesale ordering, minimum quantities, and regulatory compliance.
Our baseline OEM minimum order quantity begins at 300 pieces per model, which can be split across up to 3 distinct colorways (e.g., 100 pcs Classic Havana, 100 pcs Tokyo Tortoise, 100 pcs Jet Black). For established independent optical chains ordering recurring seasonal runs, we offer flexible framework agreements with quarterly phased deliveries.
For ready-to-ship catalog frames from our Studio Optyx brands (including Erkers1879, NW77th, Tocco, and The Neighbors), sample orders and opening stock orders begin as low as 50 pieces total.
Under EU Regulation 2017/745 on Medical Devices, corrective optical frames are classified as Class I Medical Devices. As a European manufacturing facility, we manage complete Technical Files, Unique Device Identification (UDI) implementation, and General Safety and Performance Requirements (GSPR) documentation.
Every shipment is accompanied by an official EU Declaration of Conformity (DoC), ensuring that Bulgarian optical chains, ophthalmological clinics, and EU distributors face zero regulatory scrutiny during national market surveillance inspections.
Because goods originate inside the European Union customs zone, shipments to Bulgarian destinations (Sofia, Plovdiv, Varna, Burgas, Ruse) arrive within 24 to 48 hours via standard domestic courier services (Speedy, Econt) without customs clearance delays or import brokerage fees.
For cross-border clients throughout Greece, Romania, Austria, Germany, and the wider Schengen area, consignments travel via bonded road freight or air cargo within 2 to 4 business days. No import duties, single administrative documents (SAD), or unexpected customs impounds occur.
Yes. Customization is the core of our OEM/ODM operation. We offer high-precision custom wire core embossing, enabling your brand's unique filigree or insignia to show through translucent acetate temple arms.
Branding options include laser engraving with color infill, hot foil stamping, inlaid metal temple logos, pad-printed inner temple specifications, and customized demo lenses with anti-reflective coating and UV protection marking.
We work with an extensive portfolio of high-grade optical materials:
Physical prototypes are typically fabricated, polished, and delivered within 10 to 14 business days following final CAD drawing sign-off. Once prototype samples receive client approval, bulk manufacturing of 300 to 2,000 frames is completed within 35 to 45 days.
This timeline represents a significant lead-time advantage over traditional Far East manufacturers, who frequently demand 90 to 120 production days plus 4 to 6 weeks for ocean transport.
Yes. Every retro optical frame we engineer is drafted with optical dispensing ergonomics in mind. Our acetate eyewire rims feature standardized 0.6mm V-grooves cut at a 115-degree bevel angle, providing secure retention for high minus and plus prescriptions without frame deformation.
Furthermore, our retro frame geometries maintain sufficient vertical lens depths (B-measurements > 38mm), ensuring ample reading corridor zones for modern progressive and occupational free-form multifocal lenses.
We welcome visits from eyewear brand owners, retail directors, and registered opticians to our production workshops. You can inspect our material vault, examine our 5-axis CNC machining centers, and witness hand-buffing procedures in real time.
Additionally, for premier retail practices across the region, we sponsor and organize dedicated brand trunk shows, providing extended frame sample kits, display collateral, and technical training for dispensing opticians.
Whether you are an independent boutique optician in Sofia looking to develop a proprietary house collection, or an established European fashion label scaling production of heritage optical frames, our team delivers five generations of craftsmanship, rapid turnaround, and certified quality.
