A hinge for the temples and the lens frame of glasses comprises engaging rods and bushings that are respectively formed at two sides of the lens frame and fronts ends of the temples. A spiral guiding slot and a guiding block are separately formed at an external surface of the engaging rod and at the inner surface of the bushing. The spiral guiding slots at the two sides of the lens frame have the same spiral orientation. The temples at the two sides of the lens frame are respectively slid upward and downward to be staggered in time of folding due to the cooperation of the spiral guiding slot and the guiding block. As a result, the dimension of the glasses is reduced, which conduces to convenient storage for users.
