摘要：The invention relates to providing a spectacle lens that is designed optically to
suit a spectacle frame with a large camber angle such as a wraparound type spectacleframe. 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 bythe camber angle at a design reference point, is added to a refractive surface on anobject side or a refractive surface on an eye side, prismatic power for offsetting prismaticeffect, which is caused by the camber angle at the design reference point, is added to therefractive surface on the object side or the refractive surface on the eye side, andaspherical surfaces different from each other on a nose side and an ear side are formedon the refractive surface on the object side or the refractive surface on the eye side.
