What is the SPINE hinge?

Inspired by the interaction between vertebrae, SPINE solves age-old hinge limitations. Typical optical hinges have ‘dead points’, meaning they are either open, or shut, and nothing in-between. They do not naturally have ‘give’. This limits comfort and increases fragility. In solving this issue, our design brings even more benefits. Our hinges gently flex to fit any head size, they lightly grip the face which means no more frames slipping down the face. They are durable as each part works together seamlessly, sharing each other’s load. There are no screws used in the working mechanism, so nothing to loosen, and due to the dual spring and cable the temples shut automatically when removed from the face.
