PROBLEM TO BE SOLVED: To provide apron type spectacles which are constituted by attachably/detachably attaching an apron frame to the front of the front part of spectacles, to which the apron frame is stably attached and which are prevented from being bent or twisted in the case of detaching the apron frame. SOLUTION: Magnetic bands 11 and 11 made excellent in flexibility by mixing magnetic powder are attached to the front part 1 and the inner circumference of the rim of the apron frame 2 so as to intervene between the outer circumference of a lens and the inner circumference of the rim. The outside parts 14 and 14 of the magnetic bands 11 and 11 are exposed to the surface side of the rim and the apron frame 2 is attached to the front part 1 by the magnetic force of the magnetic bands 11 and 11.
