The invention provides glasses provided with a dismountable spring hinge structure, solving the problems that existing glasses are troublesome to assemble and are not dismountable. The glasses comprise a frame and an earpiece, wherein a pile head is arranged on the frame; a hook head part is arranged on the pile head; an open slot in the hook head part inclines toward the frame; a limit slot for containing the pile head is formed in the earpiece; a spring used for hooking the hook head part and pressing the hook head part to the inner side of the earpiece so that the pile head is in the limit slot is arranged on the earpiece; one end of the spring is connected on the earpiece and the other end hooks the hook head part and has elastic pressure for pushing the hook head part to cling to the interior of the limit slot of the earpiece; the spring can rotate in the open slot and drive the earpiece to rotate to realize opening and closing of the earpiece; a gap exists between the spring and the earpiece. The glasses have the advantages that the glasses are simple to assemble, save materials and are convenient to use; when damaged, the earpiece or the frame can be immediately separated and replaced by a new part.
