## Abstract

An adjustable temple for glasses is to divide the foot of the temple into two separate parts, a foot and an ear hook. The foot includes a C shaped slot at one end having a sinewave shaped portion at bottom edge of the opening end. The ear hook includes a reduced portion integrally formed at one end adopted to insert into the slot of the foot. A rail is formed at one side of the rail adopted to guide the reduced portion to slide in the slot, and a protuberance is formed on the rail to be clamped in the sinewave shaped portion to confine movement of the rail within the slot.
