Verified wholesale optical frames and technical sun collections, calibrated for the rigorous durability standards and aesthetic tastes of Hamburg and the metropolitan Elbe region.
Understanding how Grilamid TR90 polyamide behaves under North Sea atmospheric conditions, urban bicycle commuting, and sterile commercial working environments.
Hamburg’s proximity to the Elbe and the North Sea exposes everyday items to continuous marine salinity and fluctuating humidity. Traditional cellulose acetate absorbs trace moisture over time, leading to temple warping, frame whitening (desiccation), and core-wire corrosion. Urband’s Swiss EMS TR90 polymer exhibits near-zero moisture absorption and absolute chemical inertia against brackish marine breezes, ensuring zero structural degradation in coastal environments.
With thousands of Hamburg commuters traversing the city via bicycle through rain, wind, and abrupt thermal shifts, TR90 provides high flexural fatigue strength. When fitted beneath cycling helmets or subjected to accidental impacts during rapid transit changes, the frame’s shape memory allows it to deflect under stress and immediately snap back to optical alignment without permanent plastic deformation or lens dislodgement.
Hamburg's burgeoning media, gaming, and IT sectors (Bahrenfeld, Speicherstadt) demand optical frames optimized for 10-hour desk stints. Weighing significantly less than acetate or monel metal counterparts, TR90 frames eliminate mastoid pressure points and nasal bridge indentations, making them the superior substrate for corporate blue-light filtering and progressive digital freeform lenses.
How shifting consumer values in Hamburg, Altona, and the wider DACH territory are reshaping retail procurement protocols.
German optical retail consumers actively query DIN EN ISO compliance regarding bio-compatibility. Traditional electroplated alloy temples are vulnerable to sweat-induced galvanic corrosion, causing nickel contact dermatitis. Medical-grade TR90 contains no plasticizers, heavy metals, or free monomer residues, satisfying stringent German consumer health expectations.
In accordance with the functionalist Bauhaus design ethos prized in Northern Germany, retail practices report rising friction with loose hinge screws. Urband’s patented screwless hinge and active mechanical links remove tiny hardware points of failure, practically eliminating after-sales maintenance visits for independent opticians.
With clinical myopia management interventions rapidly expanding across pediatric optometry clinics in Germany, frames must maintain precise optical centering for peripheral defocus lenses. TR90's rigid bridge geometry ensures pediatric patients retain strict pupillary distance (PD) calibration throughout active school routines.

| Elastic Memory Return | 100% Elastic Recovery (High) | Low (Requires Heat Re-alignment) | Brittle (Snaps Under Bend) | Moderate to High (Beta-Ti) |
| Salt Spray Corrosion (Hamburg Pier) | Totally Inert (Zero Oxidation) | Core wire corrosion / Bleaching | Moderate chemical degradation | Extreme corrosion resistance |
| Hypoallergenic Safety (DIN ISO 10993) | 100% Biocompatible / Nickel Free | Requires skin barrier coating | Contains trace stabilizers | 100% Biocompatible |
| Cold Impact Toughness (-10°C) | Retains High Impact Ductility | High Risk of Brittle Fracture | Prone to Stress Fractures | Retains Full Strength |
A heritage rooted in optical retail since 1960, paired with advanced French industrial design studios and vertically managed ISO-certified manufacturing hubs.
Founded by optical pioneer Yang Wah Kiang, co-founder of Nanyang Optical in Singapore. Our frame design principles stem from direct hands-on lens grinding, optical dispensing, and anatomical fitting expertise rather than purely cosmetic rendering.
Backed by an indisputable record: 14 design awards, 6 nominations, and 1 invited recognition across the iF Design Award, Red Dot Design Award, SILMO d'Or, President's Design Award, and IDSA between 2006 and 2024.
Strict fulfillment of EU Medical Device Regulation (MDR) 2017/745 Class I, CE declarations of conformity, REACH Annex XVII testing (nickel, cadmium, azo dyes, lead release), and EN ISO 12312-1:2022 sunglass ratings.
One global corporate B2B trading relationship gives Hamburg buyers direct access to five distinct specialized brands: EYELET (pediatric RX), GLOSSI (women's acetate/TR90), URBAND PARIS (sports/active), and COUPLE (ergonomic reading).
Technical, regulatory, and supply chain clarity for optical branch managers, purchasing syndicates, and specialty distributors.
Whether shipping via sea freight direct to Container Terminal Altenwerder (CTA) / Burchardkai or expedited air freight via Hamburg Airport (HAM), Urband provides complete customs documentation. Every shipment includes HS Code-certified commercial invoices (typically HS 9003.11 for plastic frames), Packing Lists with verified dimensional weight, Certificates of Origin, and product-specific EU Declaration of Conformity documents to guarantee swift ATLAS customs release.
Yes. Ophthalmic corrective frames in Germany are classified as Class I Medical Devices. Urband frames carry complete technical documentation, including biological safety evaluation under ISO 10993-1, structural stability validation under EN ISO 12870, and fully traceable Batch Quality Records ensuring full audit-readiness under German medical device oversight bodies (BfArM).
Yes. Our TR90 frame grooves are CNC-milled with standardized V-bevel angles (110° to 120°) and uniform groove depths. High-minus lenses up to -8.00D or plus lenses with standard base curves insert seamlessly via cold snap-in or gentle heating at 60°C without risk of frame deformation or crazing, ensuring precise lens wrap and optical axis integrity.
For in-stock branded inventory (EYELET, GLOSSI, URBAND PARIS, COUPLE), we offer flexible minimum orders of 50 to 100 units across mixed styles. For full OEM/ODM private-label partnerships targeting retail chain expansions across Germany, minimum production runs begin at 300 units per model, inclusive of custom pad-printing, custom pantone coloration, and localized packaging suites.
