In the world of fine eyewear, there are brands that follow trends and then there are brands that define standards.
Masunaga Optical belongs firmly in the latter.

Founded in 1905 in Fukui, Japan, Masunaga has spent more than a century perfecting the art of eyewear making. Every frame is still produced in-house, allowing complete control over quality, materials, and finish. At the very top of this legacy sits Masunaga MOC — Masters Of Craft — a collection created to showcase what is possible when design, engineering, and craftsmanship are given absolute priority.

The Philosophy Behind MOC

Masunaga MOC is not designed to appeal to everyone and that is precisely the point.

Each frame is conceived as an object of purpose and presence. Sculptural forms, confident proportions, and meticulous detailing come together to create eyewear that feels intentional rather than decorative. Production is deliberately limited, with small runs released to a select group of optical practices worldwide, ensuring the collection remains rare and highly considered.

This is eyewear for those who value restraint, integrity, and authenticity.

Craftsmanship Without Compromise

What distinguishes Masunaga MOC is the uncompromising approach to materials and execution:

• Premium Japanese acetate, layered and hand-finished for depth and strength
• Lightweight titanium structures for balance, durability, and comfort
• Sterling silver (925) detailing as a subtle signature of craftsmanship
• Thick gold plating on metal components for longevity and refinement

Every element is engineered with intention. Nothing is added without reason, and nothing is left to chance.

 Optical Frames and Sunglasses

At Spex Design Optometrist, we are proud to offer both the Masunaga MOC spectacle frames and the Masunaga MOC sunglass collection to view in store.

The sunglass range carries the same Masters Of Craft philosophy, pairing bold architectural frames with mineral glass lenses that deliver exceptional clarity and sun protection. Together, the optical and sunglass collections present the most complete expression of Masunaga’s highest-level work.

A Private Masunaga MOC Experience

For clients seeking a more personal experience or those selecting a truly special gift we offer private Masunaga MOC viewings by appointment.

During these sessions, the showroom is reserved exclusively for you. A carefully selected bottle of champagne, fine wine, or premium Scotch is poured, and time is taken to explore the collection in a calm, unhurried setting.

There are no pressure and no interruption.
Every frame is explored thoughtfully.
Every decision is intentional.

This experience is designed to honour both the craftsmanship of the collection and the individuality of the client.

Why Masunaga MOC at Spex Design

Every collection at Spex Design Optometrist is chosen deliberately. Masunaga MOC aligns with our belief that true luxury lies in quality, restraint, and the confidence of knowing something has been crafted properly.

It is eyewear for those who appreciate rarity, detail, and the quiet confidence that comes from owning something exceptional.

Experience Masunaga MOC

We invite you to visit our practice to view the Masunaga MOC spectacle and sunglass collections in store, or to enquire about a private appointment for a more tailored experience.

Because the finest eyewear is never rushed it is chosen with intention.
