An ophthalmic lens to be worn on or in a human eye for refractive correction of astigmatism, the lens having an optical axis , an anterior surface and a posterior surface , the anterior surface or the posterior surface being flat or of spherical shape, and the anterior surface and the posterior surface being shaped such that at least a zone of said lens said lens has: a first dioptric power over a first main meridian ; and a second dioptric power different from said first dioptric power over a second main meridian intersecting said first main meridian ; wherein the anterior surface and the posterior surfaces are shaped such that at least said zone of said lens has a dioptric power between said first dioptric power and said second dioptric power over each meridian between said first and second main meridians , said optical power continuously varying from meridian to meridian; characterized in that the main meridians and each meridian between the main meridians each have a different Coddington shape factor and a different asphericity that is related to the Coddington shape factor of the respective meridian in accordance with a relationship according to Fig. 3 or Fig. 4 providing spherical aberration neutral refraction for the respective meridian , wherein Fig. 3 relates to a case in which the lens is a biconvex lens, and wherein Fig. 4 relates to a case in which the lens is a concave-convex lens, and wherein: y α = ± x 2 / r 1 / 1 + 1 − K α + 1 * x 2 / r 1 2 0.5 , where: y α = sagittal height of a point on the respective meridian, x = distance to the optical axis on each meridian, r 1 = radius at apex of each meridian, and K α = conic constant of asphericity of each meridian. a first dioptric power over a first main meridian ; and a second dioptric power different from said first dioptric power over a second main meridian intersecting said first main meridian ; wherein the anterior surface and the posterior surfaces are shaped such that at least said zone of said lens has a dioptric power between said first dioptric power and said second dioptric power over each meridian between said first and second main meridians , said optical power continuously varying from meridian to meridian; characterized in that the main meridians and each meridian between the main meridians each have a different Coddington shape factor and a different asphericity that is related to the Coddington shape factor of the respective meridian in accordance with a relationship according to Fig. 3 or Fig. 4 providing spherical aberration neutral refraction for the respective meridian , wherein Fig. 3 relates to a case in which the lens is a biconvex lens, and wherein Fig. 4 relates to a case in which the lens is a concave-convex lens, and wherein: y α = ± x 2 / r 1 / 1 + 1 − K α + 1 * x 2 / r 1 2 0.5 , where: y α = sagittal height of a point on the respective meridian, x = distance to the optical axis on each meridian, r 1 = radius at apex of each meridian, and K α = conic constant of asphericity of each meridian. y α = sagittal height of a point on the respective meridian, x = distance to the optical axis on each meridian, r 1 = radius at apex of each meridian, and K α = conic constant of asphericity of each meridian. <EOS>
