Masunaga: Japanese Heritage and Professional Optometry in Marin

In the history of fine eyewear, Masunaga stands as the pioneer of the Japanese optical industry. Established in 1905 in Fukui—now the global epicenter of titanium eyewear—Masunaga has spent over a century perfecting the art of the frame. At 20/20 Optical in San Rafael, we curate Masunaga for the individual who demands uncompromising quality and a timeless, refined aesthetic. As a leading hub for optometry in Marin, we provide a sophisticated environment where 120 years of Japanese tradition meets world-class clinical care. Residents of Ross and Kentfield visit our boutique because they know we balance the legendary craftsmanship of Masunaga with the precision of a top-rated optometrist in Marin.

The technical appeal of Masunaga lies in its In-House Integration. While most brands outsource parts, Masunaga manufactures every component—including their own molds—to ensure a flawless fit. This is particularly evident in their Masunaga | K3 collection, a collaboration with the late Kenzo Takada that features intricate 18K gold and titanium detailing. Because these frames undergo over 200 manual steps, they possess a structural integrity that mass-produced frames cannot replicate. At our San Rafael showroom, David provides a precision custom fit for every Masunaga piece. Drawing on his 45 years of experience, David ensures the hand-polished acetates and custom-engineered titanium nose pads are perfectly aligned with your facial anatomy. For our clients in Tiburon searching for an optician in Marin who specializes in the maintenance of heirloom-quality Japanese eyewear, 20/20 Optical offers the specialized expertise your vision requires.

To match the "Optical Purity" of the Masunaga collection, we specialize in pairing these frames with the world's most advanced optics, including Nikon SeeMax Ultimate and Zeiss lenses. As a trusted name for comprehensive optometry in San Rafael, we focus on providing edge-to-edge clarity that matches the frame’s meticulous engineering. David works in our on-site lab to integrate Crizal Sapphire anti-reflective coatings, ensuring your lenses are virtually invisible so the focus remains on Masunaga’s subtle ornamentation and refined finishes. Whether you require high-definition progressive lenses for a board meeting or a pair of polarized Masunaga sunglasses for a drive through the Marin headlands, we ensure your visual experience is as sharp as the brand's century-old legacy.

The medical heart of 20/20 Optical is led by Dr. Kathy Ong, a highly regarded Marin County optometrist. Dr. Ong provides thorough eye health evaluations and precise prescriptions, ensuring that your artisanal Japanese frames are backed by expert medical oversight. Because Masunaga frames are designed for long-term comfort and durability, Dr. Ong often recommends them for patients who value a "medical-grade" fit that won't lose its shape over time. If you are looking for an optometrist in Marin who takes the time to understand your visual needs and your appreciation for history and precision, Dr. Ong offers the clinical excellence you expect. Whether you are choosing a classic frame from the Heritage line or a modern GMS model, 20/20 Optical is where the soul of Fukui meets the best of San Rafael optometry.
