PROBLEM TO BE SOLVED: To provide spectacle lenses in which mounting when framing the spectacle lenses into a spectacle frame is performed precisely and easily, the stress of the lenses can be reduced and the framing in a stable state into the spectacle frame is possible. SOLUTION: A rim face 30c of the spectacle lens is formed to a slope, inclined at an angleγwith respect to the lens optical axis 10 so as to face approximately parallel to an inner peripheral surface 4a of the rim 4 of the spectacle frame 3. The inclination angleγof the rim face 30c is equal to the inclination angleβ, with respect to the direction (B direction) orthogonal to the lens optical axis 10 of the rim groove 5 of the rim 4. As a result, a lens rim 33 can be made to face diametrically to and fitted into a rim groove 5 of the rim 4. COPYRIGHT: (C)2008,JPO&INPIT
