PROBLEM TO BE SOLVED: To provide spectacles where a sub frame is stably and turnably coupled with a mainframe over a long term and also which are stably held at an optional turning position. SOLUTION: The spectacles are equipped with the mainframe 2 consisting of a pair of frames 3 and 3, a bridge coupling the inner edge parts of both frames 3 and 3, a wraparound end-piece 4 coupled with the outer edge parts of the respective frames 3 and a temple 6 turnably coupled with the wraparound end-piece 4 through a hinge 5; the sub frame 8 provided on the front side of the mainframe 2 and consisting of a pair of frames 9 and 9, a bridge coupling the inner edge parts of both frames 9 and 9, and a wraparound end-piece 10 coupled with the outer edge parts of the respective frames 9; and a coupling mechanism 13 provided between the wraparound end-piece 4 of the mainframe 2 and the wraparound end-piece 10 of the sub frame 8 and relatively turnably coupling the sub frame 8 and the mainframe 2. The coupling mechanism 13 is constituted of a magnet unit 14 turnably coupling both wraparound end-pieces 4 and 10, and a guiding unit 18 turnably guiding both wraparound end-pieces 4 and 10.
