ABSTRACT:
To provide a spectacle lens that is designed optically to suit a spectacle frame with a large camber angle such as a wraparound type spectacle frame. A spectacle lens that is mounted in a spectacle frame with a camber angle of 200° or more, in which cylindrical power for offsetting astigmatic aberration, which is caused by the camber angle at a design reference point, is added to a refractive surface on an object side or a refractive surface on an eye side, prismatic power for offsetting prismatic effect, which is caused by the camber angle at the design reference point, is added to the refractive surface on the object side or the refractive surface on the eye side, and aspherical surfaces different from each other on a nose side and an ear side are formed on the refractive surface on the object side or the refractive surface on the eye side.
