A semi-finished ophthalmic lens for formation of a plurality of different finished ophthalmic lenses requiring reduced amounts of lens material to be removed for formation of the finished ophthalmic lenses and reduced rates of departure of a surfacing tool and methods of making same. Lens material is reduced by providing first and second surfaces that have different optical powers, the second optical surface having a second curve that approximates second optical surfaces of a plurality of finished ophthalmic lenses at coordinates at which lenses of the plurality of finished ophthalmic lenses have maximum thicknesses.
