A rigid material such as wood needs special arrangements to allow maximum wearing comfort and an easy way to mounting the lenses. The masks from which the glasses are obtained have a spherical curvature, non-cylindrical, so as to facilitate the mounting of vision lenses (spherical). Rimlock, housed in the nose area, help this operation. Flex hinge retractable and adjustable terminal acetate optimize the fit. The curved snout and fins wood made are synonymous of accuracy and enhance the design. Each pair of Dolpi glasses weighs only 24 gr.
