Explore our flagship precision-engineered acetate and titanium eyewear series designed for global enterprise procurement.
Navigating European Medical Device Regulations (MDR EU 2017/745) and ISO Standards for Optical Lenses & Eyewear Procurement.
Under European Union regulations, corrective optical lenses and prescription frames are categorized as Class I Medical Devices. CE Marking is not merely a label; it represents rigorous adherence to essential health, safety, and biometric compatibility criteria. Our optics manufacturing process complies with strict technical documentation mandates, declaration of conformity protocols, and continuous post-market surveillance.
All optical lenses manufactured at our facility undergo fundamental performance testing governed by ISO 8980-1 (Uncut finished spectacle lenses), ISO 8980-2 (Transmittance specifications), and EN ISO 14889 requirements. This ensures structural impact resistance, optical clarity, zero geometric aberration, optical axis stability, and 100% UV spectral cut-off up to 400nm wavelength.
Frame materials, including Italian Mazzucchelli bio-acetate and 100% Pure Japanese Titanium (β-Titanium), are strictly verified for biocompatibility (EN ISO 10993). Nickel release testing under EN 16128 guarantees non-allergenic contact for wearers, while RoHS compliance ensures zero heavy metal toxicity across coatings, dyes, and structural components.

How localized industrial synergy and vertical Integration deliver total cost ownership (TCO) optimization for global optical distributors.
Shenzhen, Guangdong Province, stands as the global epicenter for high-end optical lens production and precision frame crafting. Processing over 70% of the world's premium optical goods, the local supply chain infrastructure offers unmatched efficiency in sourcing rare raw materials, specialized high-index resins, ultra-pure titanium sheets, and custom metal hinges.
By maintaining our state-of-the-art facility in Fuji Land Building Industrial Park, Yintai Eyewear leverages immediate proximity to advanced surface treatment labs, PVD vacuum plating facilities, and specialized mold tooling masters. This cluster effect dramatically reduces lead times from initial 3D design to prototype validation by up to 40% compared to fragmented international supply chains.
Yintai Eyewear brings 15 years of dedicated R&D, precision manufacturing expertise, and scale to enterprise buyers.
Located in the industrial park at Fuji Land Building, equipped with: fully automated production lines, CNC machining centers, Class 10,000 cleanrooms, and more, ensuring both stable production capacity and consistent quality.
We have over 200 dedicated employees, including a 10-member elite R&D and technical team that continuously drives product innovation and process optimization.
From raw material procurement and mold development to finished product assembly, we have achieved vertical integration across core production processes. This translates to more controllable costs, faster delivery cycles, and more consistent product quality.
Comprehensive OEM/ODM capabilities designed for optical chains, retail distributors, and prescription eyewear brands worldwide.
Integrating next-generation material science and optical design to meet evolving consumer and medical demands.
As wearers prioritize ergonomic comfort, pure titanium (Japanese Grade 1/2) and β-titanium frames weighing under 15 grams have become the industry standard. High strength-to-weight ratios combined with hand-carved detailing deliver ultimate durability without skin irritation.
Modern digital lifestyle requires hybrid lenses that integrate high-transmittance HEV blue-light absorption (415nm-455nm filtering) with fast-responding spin-coating photochromic technology, transitioning seamlessly from indoor clarity to outdoor UV protection.
Environmental sustainability drives global retail compliance. We utilize bio-degradable acetate derived from plant-based cellulose flakes (free from traditional chemical plasticizers), fulfilling EU REACH standards while preserving rich color depth and hand-polished lustre.
Tailored optical engineering solutions customized for diverse demographic markets, professional environments, and healthcare networks.
Designed for white-collar professionals spending extended hours before screen displays. Lightweight titanium round and square frames paired with anti-reflective, blue-light filtering lenses minimize eye fatigue, prevent computer vision syndrome (CVS), and present an elegant minimalist aesthetic suitable for corporate environments across North America and Europe.
Optometric practices and boutique optical stores require high structural stability for easy lens edging and mounting. Our thick-rim vintage acetate and hand-carved titanium frames feature reinforced 5-barrel or 7-barrel hinges, allowing seamless lens insertion by opticians without structural warping.
Technical, regulatory, and commercial answers for optical buyers, importers, and brand owners.
Select from our extensive catalog of certified titanium, acetate, and rimless optical frame solutions.
