Lineus // Tortoise

Lineus introduces DITA’s most innovative sun clip concept to date, adapting the label’s signature cutout acetate frames to achieve a simple, elegant solution for convertible sun lenses.

Design that finds beauty in purpose

A traditional clip-on lenses require four hooks to securely fasten the clip to the front frame; Lineus features a notch beneath the temple, allowing a sun clip to seamlessly attach to the frame’s exposed titanium core using just two side hooks.

Craftsmanship that celebrates the unseen

Lineus’s temples feature two pieces of acetate, connected by a titanium core; the titanium allows for flexibility and reduces tension at a critical juncture, ensuring comfort while repeating the frame’s signature cutout detail.

Culture that transcends convention

Elegant solutions to technical problems are a hallmark of DITA’s commitment to optical innovation. Lineus reduces mechanical tension through the frame through clever construction, and limits the need for users to touch the clip-on lens with their hands while affixing it to the frame.
