About Elistro Dealer Program ContactEvery SKU is engineered for repeatable prescription mounting, dimensional stability during heat customization, and compliance with European CE standards (EN ISO 12870:2018).
Integrating traditional hand-finishing craftsmanship with high-throughput ISO-compliant optical testing lines to mitigate procurement risks for B2B distributors.
Every batch undergoes mechanical endurance testing (20,000 hinge flex cycles), perspiration testing according to ISO 12870 clauses, bridge deformation resistance, and dimensional stability checks under thermal stress up to 60°C.
We use aged, low-plasticizer Italian/Mazzucchelli-grade cotton-derived cellulose acetate sheets. CNC cut fronts undergo 72 hours of multi-stage tumbling in walnut and pumice barrels followed by hand buffing to yield silky nose bridges.
Aerospace-grade pure titanium (Grade 2) and Beta-Titanium alloys eliminate heavy nickel migration (complying with REACH standard EN 16128). IP vacuum ion plating preserves luster against skin perspiration.
Lower your retail merchandising costs. Every wholesale frame can be bundled with an OEM customized structural rigid hard case, high-density microfiber cloth, certificate warranty card, and foil-stamped gift box.
We provide complete optical parameters (A/B measurement, DBL bridge width, ED effective diameter, and temple length) engraved clearly via laser on inner arms to expedite laboratory lens edging.
Support independent optometry practices and national retail distribution networks. Choose from ready-to-ship catalog inventory (low MOQ 50-100 pcs) or fully bespoke architectural tooling (300-500 pcs/colorway).
Optimize your seasonal buying budget by matching demographic prescription demands with optimal chassis metallurgy and polymer tensile strengths.
| Technical Characteristic | Cellulose Acetate (Organic) | Beta-Titanium (Aerospace) | Medical Stainless Steel (AISI 304/316) | High-Tensile TR90 / Polymer |

How progressive optical chains and regional brand buyers are adapting their supply chain strategy for 2026-2030 market leadership.
Regulatory bodies and modern eco-conscious optical consumers are steering global demand toward bio-acetate—formulated using plant-derived diethyl phthalate substitutes. Optical businesses are prioritizing suppliers with certified zero-waste tumbling systems and closed-loop chemical reclamation to satisfy incoming European Corporate Sustainability Due Diligence Directives (CSDDD).
Optical retail displays are rapidly evolving to feature architectural frames with modular temple channels ready to accommodate miniaturized bone-conduction transducers or electrochromic variable tint lenses. Sourcing teams are selecting chassis architectures that blend traditional ophthalmic glaze grooves with rigid structural reinforcement at the hinge lug.
Rather than holding heavy capital in static retail stock, multi-branch optical dispensaries are moving toward digitally synchronized procurement. By utilizing our centralized high-definition 3D CAD libraries, AR try-on assets, and low-run batch replenishment, optical entrepreneurs compress lead times from 90 days to under 10 business days for rapid reorders.
Clear answers to vital regulatory, dimensional, and supply inquiries for B2B optical buyers.
Our products are registered under EU Medical Device Regulation (MDR 2017/745) Class I for corrective spectacle frames. We provide the complete Declaration of Conformity (DoC), technical construction files (TCF), test certificates for EN ISO 12870:2018 (endurance, ignition, perspiration, and bridge deformation), and REACH Annex XVII nickel release compliance reports (EN 16128:2015).
All eyewires and rim profiles are cut with standardized 115° to 120° V-grooves at uniform depths of 0.55mm to 0.65mm. This eliminates lens slippage or pin-out issues during installation on Essilor, Nidek, or Briot computerized edgers, accommodating both shallow demo lenses and high base curves (2C through 6C).
Yes. We offer high-definition fiber laser engraving on inner temple arms, nose pads, and demo lenses. In addition, our integrated packaging workshop provides customized rigid clamshell cases, microfiber cloths with hot-stamped logos, and exterior presentation boxes with Pantone-matched cardstock.
For ready-to-ship catalog frames (acetate or titanium), our MOQ starts at 50 to 100 units across mixed colorways, shipping within 7 business days. For customized OEM manufacturing (bespoke shapes or custom color acetates), the MOQ is 300 to 500 units per style, with a standard production cycle of 45 to 60 days including tool preparation.
Finished frames are stabilized using computerized oven stress-relief cycles prior to assembly. Frames are individually sealed in anti-static PE sleeves with silica gel desiccants and packaged in rigid internal divider cartons designed to withstand maritime humidity and high-pressure container stacking.
Our in-house R&D team provides full 3D DFM (Design for Manufacturing) evaluations. We assist international clients in tailoring bridge curves and nose pad geometry to specific demographic anthropometrics—including Asian fit, European universal fit, and wide bridge configurations.
