Abstract: A pair of eyeglasses includes two temples connected to a lens seat unit by two connecting seats, respectively. Each of the connecting seats includes a first pivotal portion, an intermediate portion, and a second pivotal portion having two pivotal plates. Each of the intermediate portions has first and second vertical walls, and upper and lower horizontal walls so as to define a retaining space. Each of the temples includes a retaining portion inserted into the retaining space in the corresponding connecting seat, and a pivotal portion connected fixedly to the retaining portion and connected pivotally to the pivotal plates of the corresponding connecting seat. In each of the connecting seats, the first vertical wall is formed with a rib engaging a selected one of positioning slots in the retaining portion of the corresponding temple. The ribs and the positioning slots are concealed within the connecting seats.
