ABSTRACT:
A hinge for glasses pivotably connects an endpiece (2) attached directly on a lens (3) or provided on a frame with a temple (1). The hinge has a hinge pin (12) held rotatably in a hinge support (22) of the endpiece (2), which hinge pin is disposed on the temple (1). The hinge pin (12) forms a predetermined breaking point (122) for the hinge, which releases the temple (1) when an admissible force on the endpiece (2) is exceeded. A preferred embodiment is described, according to which the hinge pin (12) is formed in one piece with the temple (1) in an injection molding process.
