A finished uncut spectacle lens has a curved front surface including an optical bowl with a convex curvature and a peripheral lentic zone surrounding the optical bowl. The curvature of the curved front surface in the peripheral lentic zone is flatter than in the optical bowl. The optical bowl size is large enough that a lens filling the entire frame can be glazed from it. The inclusion of a flatter peripheral lentic zone enables a larger diameter of the finished unglazed lens (d) with larger edge thickness than would be possible if the same back surface was cut on a semi-finished blank having a uniform spherical front, without compromise to the finished lens center thickness. In addition, a method of manufacturing such a spectacle lens and a semi-finished lens blank used in the method are provided.
