An ophthalmic lens , comprising: a posterior surface having a central optic zone , a peripheral zone , and a blending zone therebetween; the central zone being toric; and the blending zone forming a smoothened transition between the central zone and the peripheral zone , the blending zone described at least in part by spline curves, characterized in that - the central zone is asphero-toric and defined by the equation: z = cx x 2 + cy y 2 1 + 1 − 1 + kx cx 2 x 2 − 1 + ky cy 2 y 2 where z, x, and y are coordinates relative to respective z-, x-, and y-axes, cx = 1/apex radius x, cy = 1/apex radius y, and kx and ky are conic constants relative to the respective x- and y-axes, where -2.0 < kx < 0.0 and -2.0 < ky < 0.0; - the peripheral zone is aspheric, rotationally symmetrical about the z-axis, and defined by the equation: z = cx x 2 1 + 1 − 1 + kx cx 2 x 2 where z and x are coordinates relative to the respective z- and x-axes, cx = 1/ apex radius x, and kx is the conic constant, where -2.0 < kx < 0.0; - along a first cylindrical meridian (R0) and a second spherical meridian (R90) the slope changes of the spline curves in the blending zone are opposite and about the same in magnitude, and along a third meridian (R45) halfway between the first cylindrical meridian and the second spherical meridian in the blending zone a continuation of the central zone generally matches a continuation of the peripheral zone ; - wherein the spline curve in the blending zone gradually changes from steep to flat from the central zone to the peripheral zone along the first cylindrical meridian (R0), and wherein the spline curve in the blending zone gradually changes from flat to steep from the central zone to the peripheral zone at the second spherical meridian (R90). a posterior surface having a central optic zone , a peripheral zone , and a blending zone therebetween; the central zone being toric; and the blending zone forming a smoothened transition between the central zone and the peripheral zone , the blending zone described at least in part by spline curves, - the central zone is asphero-toric and defined by the equation: z = cx x 2 + cy y 2 1 + 1 − 1 + kx cx 2 x 2 − 1 + ky cy 2 y 2 where z, x, and y are coordinates relative to respective z-, x-, and y-axes, cx = 1/apex radius x, cy = 1/apex radius y, and kx and ky are conic constants relative to the respective x- and y-axes, where -2.0 < kx < 0.0 and -2.0 < ky < 0.0; - the peripheral zone is aspheric, rotationally symmetrical about the z-axis, and defined by the equation: z = cx x 2 1 + 1 − 1 + kx cx 2 x 2 where z and x are coordinates relative to the respective z- and x-axes, cx = 1/ apex radius x, and kx is the conic constant, where -2.0 < kx < 0.0; - along a first cylindrical meridian (R0) and a second spherical meridian (R90) the slope changes of the spline curves in the blending zone are opposite and about the same in magnitude, and along a third meridian (R45) halfway between the first cylindrical meridian and the second spherical meridian in the blending zone a continuation of the central zone generally matches a continuation of the peripheral zone ; - wherein the spline curve in the blending zone gradually changes from steep to flat from the central zone to the peripheral zone along the first cylindrical meridian (R0), and wherein the spline curve in the blending zone gradually changes from flat to steep from the central zone to the peripheral zone at the second spherical meridian (R90). <EOS>
