Explore our foundational optical and performance frames engineered with aerospace polymers, high-density acetate, and surgical-grade metals compliant with Japanese JIS B 7285 frame standards.
A technical overview of material dynamics, consumer expectations across Kansai commercial hubs, and how export-ready precision OEM manufacturing satisfies stringent Japanese retail criteria.
The Kansai metropolitan region—centered on Osaka, Kobe, and Kyoto—represents Japan's second-largest eyewear retail theater. For decades, Japanese optical chains like Megane Ichiba, JINS, and Zoff have educated Osaka consumers on the merits of featherlight polymer frames. However, market intelligence demonstrates a marked evolution in consumer intent: modern Osaka eyewear users demand high dimensional stability, non-slip Asian cranial curvature, and structural endurance that exceeds typical bargain-tier polycarbonate offerings.
As an international manufacturing powerhouse rooted in Singapore since 1960 and operating advanced CNC, molding, and testing centers in Shenzhen alongside our French design atelier, we bridge this commercial demand. TR90 (polyamide Grilamid TR) has emerged as the definitive material answer for Japanese optometrists and mass retailers seeking to minimize warranty returns and achieve superior tactile satisfaction.
Our TR90 formulations eliminate the embrittlement typically caused by high sebum exposure, summer humidity along Osaka Bay, and frequent optical bench heating during lens mounting.
| Performance Metric | Commercial Virgin TR90 (Our Factory) | Secondary Recycled TR90 | Standard Polycarbonate (PC) | Traditional Cellulose Acetate |
|---|---|---|---|---|
| Specific Density | 1.02 – 1.05 g/cm³ (Featherlight) | 1.12 – 1.18 g/cm³ (Inconsistent) | 1.20 – 1.25 g/cm³ (Noticeable Mass) | 1.28 – 1.32 g/cm³ (Heavy Structure) |
| Flexural Elastic Memory | Superior (Recovers original curvature) | Moderate (Prone to permanent warp) | Brittle (Snaps under cold deflection) | Thermo-plastic (Requires wire reinforcement) |
| Hydrolytic Stability | Negligible moisture swell (<0.2%) | Elevated absorption causes clouding | Prone to stress cracking with solvents | Absorbs skin sweat and discolors |
| Heat Deflection Temp | 175°C (Stable during thermal glazing) | <130°C (Distorts in display heat) | 135°C (Rigid frame stress) | 110°C (Requires warm water softening) |
| Suitability for High-Diopter Rx | Exceptional (No bevel slippage) | Risk of groove deflection | Poor edge retention | High (Classic optical fit) |
Strategic categorization matching the varied demographic and socioeconomic retail micro-climates of the Kansai metropolitan corridor.
Office executives, developers, and corporate professionals commuting along the Midosuji Line demand frames offering blue-light filter capability without clamping pressure. Our ergonomic TR90 rectangle and pantos-cut silhouettes exert gentle, calibrated lateral pressure (<1.2N), entirely preventing temporal headaches during 10-hour screen sessions.
Cyclists on the Yodogawa river trails, amateur pickleball players around Nanko, and marine sports enthusiasts require wraparound aerodynamics. Utilizing TR90 sports frames coupled with polycarbonate amber contrast lenses ensures impact resistance against gravel, sweat impermeability, and continuous frame stability without slipping.
Children in elementary schools across Osaka Prefecture require frames that withstand intense kinetic movement. Harnessing our award-winning EYELET innovation, we integrate flexible TR90 fronts with our proprietary nylon-string soft-lock temple mechanism—eliminating loosened screws and protecting developing nasal bridges from blunt impact trauma.
With Japan's hyper-aging demographic, Osaka's mature population demands reading and progressive eyewear that feels virtually weightless on fragile skin. Our COUPLE series utilizes ultra-slim TR90 bridges with oversized vertical depths, supporting modern multifocal digital lenses without localized pressure sores or slippage.
Osaka’s vibrant street fashion and artistic youth culture crave distinctive geometries without the heavy, encumbering weight of industrial acetate. We supply translucent jewel-toned and matte frosted TR90 frames with sculpted brow lines that mirror luxury bespoke silhouettes while preserving lightweight all-day comfort.
Retail optical chain store operators across Osaka Station underground concourses and major suburbs thrive on 30-minute edging and delivery workflows. Our TR90 frame series features high thermal tolerance for rapid cold-snap or heated lens insertion, preventing rim roll and ensuring rapid technician throughput without breakage.
Actionable data and technical adaptations required to capture consumer demand in Japan's hyper-competitive retail optical climate.
Generic Western optical designs frequently cause irritation and visual axis misalignment for Japanese wearers due to narrower pupillary distances, flatter bridge profiles, and pronounced zygomatic cheekbones. Our export frames for Osaka incorporate an engineered 3D pad-arm geometry with a 14mm to 16mm bridge apex, ensuring adequate clearance from eyelashes while keeping progressive optical centers perfectly positioned.
Japanese customs clearance and consumer protection laws enforce stringent oversight on toxic volatile organic compounds (VOCs). Every TR90 production batch from our facility undergoes comprehensive REACH screening, verifying total absence of nickel release, lead traces, and carcinogenic phthalates. This guarantees trouble-free compliance under Japan’s Pharmaceutical and Medical Devices Act (PMD Act) standards for non-corrective frame imports.
With high myopia incidence in Japan exceeding 65% among urban adults, frames must cleanly conceal thicker 1.67 and 1.74 ultra-high-index lens edges. Our TR90 engineering optimizes rim thickness and utilizes an inward-beveled V-groove architecture that structurally supports high diopter lenses without bowing the front bridge or displacing temple parallelism.
Combining Singapore optical roots, European aesthetic styling, Japanese R&D precision, and high-capacity manufacturing in Shenzhen.
Urband International’s legacy began in 1960 when our founder, Yang Wah Kiang, co-established Nanyang Optical in Singapore after mastering the fine mechanics of hand lens grinding in the 1950s. This profound clinical understanding of lens surfacing, pupillary axes, and bridge biomechanics forms the bedrock of every frame we manufacture today.
Rather than functioning as a standard contract injection shop, we coordinate an integrated global optical matrix: an advanced Design Studio in Greater Paris providing sophisticated silhouettes; historical R&D engineering collaboration with Japan; and a world-class 8,000 m² high-precision manufacturing campus in Longgang, Shenzhen, housing computer-controlled multi-axis CNC machines and automated Swiss polymer molding cells.
Our work has been honored with 21 international design recognitions between 2006 and 2024, including accolades associated with the iF Design Award, Red Dot Design Award, SILMO d'Or, and Singapore President's Design Award.

Yes. Our TR90 optical frames are rigorously designed and engineered to satisfy JIS B 7285 (Ophthalmic optics — Spectacle frames) requirements. This encompasses rigorous endurance against continuous temple folding (minimum 5,000 cycles without hinge mechanical failure), dimensional stability under 60°C thermal exposure, non-deformation under mechanical lateral loading, and complete sweat/perspiration corrosion resistance for all internal wire cores and pad arms.
Standard European/Western frames frequently exhibit pantoscopic tilt and bridge widths (18mm–21mm) that slide down flatter nasal bridges and press against prominent cheekbones. Our specialized molds for Japanese and East Asian markets feature narrower bridge widths (15mm–16mm), a steeper nasal contact angle (splay angle of 28°–32°), deeper integrated or adjustable beta-titanium pad arms, and a flatter front frame wrap angle of 4° to 5° to prevent lens-to-cheek contact.
We routinely dispatch ocean freight shipments from Shenzhen (Yantian/Shekou) directly to the Port of Osaka or Port of Kobe with an ocean voyage time of approximately 4 to 6 business days.
