Spine-Inspired Hinge

Modeled after the human spine, the revolutionary eyeglasses hinge from Spine Optics holds eyeglasses securely in place with a gentle spring tension.

Instead of rotating on a screw, the hinge is made up of a series of segments connected to a pair of springs. The new arrangement takes the stress off the hinge area while creating a gentle tension that “clamps” the glasses to the head for a snug fit, which also allows a single frame to fit different-sized heads.
