OVERVIEW
Premium eyewear clusters in a few regions not simply because they have skilled artisans, but because many different processes are connected at close range
Follow premium eyewear manufacturing and the same place names recur: Fukui and Sabae in Japan, Morez and the Jura in France, and Belluno in Italy. Different brands often share the same production regions.
It is only half-correct to explain this by saying those regions have better hand skills. A frame can involve cutting, pressing, brazing, polishing, plating, hinges, wirecores, acetate, titanium, assembly and inspection. Premium products usually tighten the tolerances and finishing expectations between those processes.
These regions are not powerful because one factory contains every operation. Their advantage comes from a long-developed ecosystem of specialist firms and craftspeople that can divide the work, correct problems and test new materials or constructions without rebuilding the supply chain from zero.
This Brief does not rank Japan, France and Italy against one another. It asks why premium eyewear repeatedly returns to a small number of manufacturing clusters, and what those clusters have to maintain if the advantage is to survive.
01 · CLUSTER, NOT ONE FACTORY
The difference in premium manufacturing often comes from the density and speed of specialist connections rather than one factory’s capability
Eyewear uses more processes than its small size suggests. Metal and acetate frames need different techniques, while a metal frame alone may require pressing, machining, brazing, surface treatment and plating.
In a cluster, one company does not need to internalize every skill. A design company can revise samples with a prototyping specialist, hardware suppliers can provide hinges and wirecores, and polishing or plating companies can finish the surface.
The advantage is not only cost. When a new frame fails, proximity shortens the loop between design, machining, sample and correction. Small-volume products can still access highly specialized processes.
Premium collections often have smaller runs, more material variation and more finishing options than mass retail. A dense network of specialist workshops can therefore be better suited to complex low-volume production than one very large standardized plant.
02 · SABAE
Sabae grew through a distributed system that has often functioned like an entire city acting as one factory
Sabae City currently describes itself as the center of a region producing more than 96% of Japan’s domestically made spectacle frames. Fukui’s eyewear industry began in 1905 when Masunaga Gozaemon invited craftsmen from Osaka to teach local residents frame making.
Fukui’s eyewear industry began in 1905 when Masunaga Gozaemon invited craftsmen from Osaka to transfer frame-making skills. Sabae City says the industry later developed through division of labor, which pushed individual firms and craftspeople toward deeper specialization.
That structure leaves titanium processing, pressing, machining, lasers, joining, surface treatment and finishing spread across multiple local specialists rather than concentrated inside a single vertically integrated factory.
The modern advantage is not history alone. Titanium processing, lasers, plating, machining and polishing companies remain connected in the same region, and many of those technologies now extend into medical and electronic components.
03 · MOREZ / JURA
The French Jura shows how an existing metalworking culture can evolve into a specialized eyewear industry
Morez traces its eyewear story to 1796, when a local nail maker used wire to make a spectacle frame. The region already had water-powered metalworking, clockmaking and enamel trades.
Morez became a major French eyewear center during the nineteenth century. Jura Tourisme still describes it as the nerve center of French frame making, with around 1,500 industry employees and roughly two million frames produced annually.
The Jura advantage is therefore more concrete than a vague idea of French taste. It includes metalworking, surface finishing, small-series production and hand finishing that have accumulated within the same geographic area.
The training system also remains close to industry. Lycée Victor Bérard in Morez explicitly describes its optical and eyewear programs as developing in close relationship with local manufacturers and sector institutions.
04 · BELLUNO
Belluno combines artisanal production and large-scale industrial manufacturing inside one unusually dense eyewear district
Belluno in Veneto is the center of Italian eyewear manufacturing. The Italian Trade Agency describes the 2025 industry as roughly 800 companies, 22,000 workers and €5.64 billion in production value.
The same source says more than 80% of Italian eyewear production is concentrated in Veneto, particularly Belluno. The area around Pieve di Cadore, Agordo, Lozza and Longarone alone accounts for more than 70% of national production.
The district contains major international groups including EssilorLuxottica, Safilo, De Rigo, Marcolin and Thélios alongside many smaller manufacturers and specialist suppliers.
That means global licensing, high-volume production and smaller premium work do not exist in completely separate worlds. Tooling, components, product development, quality control and production-management talent can circulate within one broad industrial ecosystem.
05 · WHY PREMIUM BRANDS RETURN TO THESE REGIONS
The attraction is less expensive material than the ability to repeat complex processes at small volumes
Premium brands often produce fewer units than mass-market chains while using more variation in material, hardware, colour and finishing. That production model requires flexibility rather than only maximum throughput.
In mature clusters, suppliers can be recombined around a project. A different plating finish can be tested with one specialist, while a new hinge may require a separate component and machining partner.
Repeated correction is also easier. Premium quality depends less on the fact that something was handmade than on whether very small differences can be revised several times without losing consistency.
The production-place name therefore becomes a compressed description of a supply network. ‘Made in Sabae’ or ‘Made in Jura’ can point to multiple companies and technical relationships rather than one workshop.
06 · QUALITY AS A SYSTEM
Premium quality depends less on one famous craftsperson than on standards surviving from one process to the next
A frame can be excellent at one stage and still fail later. Accurate machining can lose its line in polishing; precise brazing can be distorted during plating or assembly.
The strength of a mature cluster is not merely having many good processors. Companies understand what the next process needs and share practical language about where a problem should be corrected.
Much of that coordination is tacit. It sits in repeated transactions, local habits, quality expectations and experience rather than only in CAD files and specifications.
This is one reason premium brands may hesitate to move production. Changing a factory can mean rebuilding not one supplier relationship but an entire chain of process knowledge, inspection habits and human coordination.
07 · ARE THESE THE ONLY PLACES THAT CAN MAKE GOOD EYEWEAR?
Recognizing cluster strength is different from assuming other countries lack advanced manufacturing capability
It would be inaccurate to treat Japan, France and Italy as the exclusive homes of premium eyewear. China, Korea and other countries have highly capable machining, metal, acetate and electronics industries.
In high-volume manufacturing, automation, cost efficiency and smart-eyewear electronics, different supply chains may be stronger than traditional European or Japanese frame clusters.
What distinguishes Sabae, the Jura and Belluno is not that others cannot make a good frame. It is the accumulated concentration of eyewear-specific suppliers that understand small changes, finishing expectations and frame-specific production problems.
Country of origin alone is therefore a weak quality test. A more useful question is which processes a brand performs where, how the supplier network is organized and what quality-control system connects those steps.
08 · OLD CLUSTERS DO NOT SURVIVE AUTOMATICALLY
The deeper the specialization becomes, the harder the network can be to rebuild when people or suppliers disappear
Manufacturing clusters do not survive on history alone. In 2026 Sabae City explicitly identified successor recruitment, skill transfer and limited capacity for capital investment as shared challenges facing local manufacturing industries.
Belluno is also investing in training. A 2026 MIDO profile of the ITS Eyewear Product Manager program highlighted a historical placement rate above 87% and extensive company internships as part of the district’s talent pipeline.
Morez likewise keeps optical and eyewear education inside the local industrial environment. For the name of a production region to remain meaningful, workshops, schools, younger technicians and new equipment all have to stay connected.
Deep division of labor also creates vulnerability: the loss of one highly specialized supplier can affect the rest of the chain. Preserving old skills and attracting new people therefore become the same industrial problem.
09 · THE NEXT GENERATION OF CLUSTERS
Future manufacturing centers will probably combine inherited craft with digital design, automation and smart-eyewear technology
Sabae has already extended frame-making technologies into medical and electronic components, and in 2026 the city was publicly discussing smart glasses and IT as a new industrial opportunity.
Belluno’s mix of large groups, smaller manufacturers and training institutions similarly gives it an infrastructure capable of absorbing new materials and production technologies alongside traditional frames.
The next competitive advantage may therefore depend less on how long hand skills have been preserved and more on how quickly those skills can connect with digital design, automation, new materials, sensors and electronics.
Premium eyewear remains concentrated in certain regions not because the past is old, but because those regions still have enough technical relationships to recombine themselves when the next product changes.
GLANOS VIEW
A strong production region is less a place with many factories than a place where the technical relationships needed to remake a product still exist
Sabae, the Jura and Belluno share something more important than age: division of labor and connection. Multiple specialists build one object and understand enough of one another’s processes to move backward when a problem appears.
In that system, knowledge is stored not only in machinery and drawings but also in people, trading relationships, local schools, small processors and repeated working habits.
That is why moving production can be harder than changing an address. Even with similar equipment, the links and judgment standards between processes take time to rebuild.
The real asset of premium manufacturing is therefore not the origin label itself, but whether the region can continue to reproduce the capability needed to make the next product.
