Our passion for artisanal eyewear takes us on a yearly trip back to Japan.
Eye Theory’s eyewear collection is ever-expanding to include a range of makers with varying approaches to design and daily functionality. We want glasses that make us stop and look twice. Not because of pure aesthetics, but the heart behind them. Glasses that are made with intention. Curated with quality materials. A well-crafted pair of glasses should always reflect the purpose behind its construct.
Enter Sabae. This small and unassuming city in Fukui, Japan carries a massive reputation. It’s one of the world’s leading eyewear manufacturers.
A frame’s character is often found in the little details. For generations, Sabae’s skilled eyewear makers have quietly poured their vision into their work. While they share the same foundation in Japanese craftsmanship, everyone has their own idea of what a great frame should be.
Our two new favourite labels, Naito Kumahachi and Leowl in eye, are housed by the same Sabae-based maker, Naito Optical. Both labels carry its own unique personality.
Together, they make the perfect introduction to genuine and classic artisanal eyewear. The kind that reads ‘Made in Japan’ in a shimmery small font, on the underside of its case.

Naito Kumahachi: A bridge between past and modernity
Naito Kumahachi or in short, Kumahachi was born from a love for vintage eyewear. A beloved original label of Naito Optical, its shapes possess a familiar old-school flair.
Upon closer look, you’ll notice how the curve of its bridge, delicate engravings, blend of materials, and the way its frame flows to meet its temples tell a unique and interesting story.
Why celluloid frames add charm
Naito Kumahachi draws much of its refined character from celluloid. Unlike conventional plastic frames that look dull and uniform, celluloid adds a warm richness and dimension to its frames that catch the light when polished, almost transporting its wearer back to another time.
What you get is a refined pair of glasses that’s classy and sleek without overdoing it. Casual enough for everyday wear with just a touch of je ne sais quoi.
Naito Kumahachi’s subtle, classic collection makes a gentle yet refreshing start for anyone who’s new to Japanese eyewear.
Leowl in eye: Soft framing with bold character
Like the round, curious eyes of an owl, Leowl in eye explores softer, circular frames that feel almost whimsical in nature.
Complementary colours, fine detailing, and careful choice of materials keeps its frames expressive without having to shout about it.
Its subtle stylishness allows it to double as a quiet fashion statement that can become a distinctive part of your everyday look.
Gentler and more playful in style, Leowl in eye’s attention to detail stays true to its deep roots in Japanese craftsmanship.
