This collection was developed with the aim of irritating wearers with as little weight as possible. Consequently, the ZERO+A1 frame comes with a light and slim design. Since the frame consists of stainless steel, it is resistant and, despite its delicate structure, provides a secure hold. The hinge system does without screws or welded connections. All components are adjustable, allowing the glasses to be precisely fitted to the shapes of the face and of the head.
