Every Barton Perreira frame is handmade in Japan by highly skilled artisans and craftsmen. A rigorous six-to-eight-week manufacturing process focuses on perfecting every detail, from the frame’s foundation to its deep glossy finish. This meticulous process results in beautiful eyewear with an emphasis on finish, feel, and fit.
Barton Perreira believes that every pair of glasses should fit as perfectly as a well-tailored piece of clothing. To ensure this, all of their plastic frames contain metal corewiring, providing a skeletal foundation that allows each frame to be adjusted to fit the wearer’s face while also helping them keep their unique form. In order to achieve their signature lightweight frames, a resin-based polymer plastic called zylonite is employed. It’s tumbled for several days before being hand polished twice to create a seamlessly smooth surface. This material selection and uncompromising process results in a light, durable product with a deep gloss finish.
