Summary:PURPOSE:To vary the angle of spectacles while moving up and down lenses by fitting both bows outside of both lens frames vertically rotatably, and by bending both nose pieces or making them vertically movable. CONSTITUTION:Channel-shaped supporting frames 6 are fitted to the outside parts of lens frames 2 of spectacles for short-sighted and long-sighted eyes, one end of a coupling piece 10 is inserted between an upper plate 7 and a lower plate 9, and the coupling piece and side plate 8 are fitted rotatably. To the lower part of a center coupling piece 3, nose pieces 14 are fitted through supporting bodies 13. Each nose piece is bent up and down in a dogleg shape and has an upper contact surface 15 and a lower contact surface 16 on the surface. When distances between the upper and lower contact surfaces and the angle of the lenses are different, the same effect is obtained, and the upper and lower contact surfaces may be provided on different supporting bodies. Further, one contact surface may be made vertically rotatable.
