PROBLEM TO BE SOLVED: To provide eyeglasses in which a lens is easily attached to and detached from a frame and a nose pad, so that the lens is very easily replaced, and further when the lens is mounted on the frame and the nose pad, the lens is not distorted, and the optical performance and strength of the lens are not adversely affected. SOLUTION: An elastically deformable locking member 2 comprising a pair of locking claws 2a, 2b is projectingly provided in at least one location of an outer peripheral edge of a lens 1, an angle at which the centerline Ca of one locking claw 2a crosses the centerline Cb of the other locking claw 2b is 10 to 120 degrees, the locking member 2 is locked to at least either of a lens frame 3 and a nose pad 4.
