An ophthalmic lens for at least one of slowing, retarding or preventing myopia progression, the ophthalmic lens comprising: a center zone with a negative power for myopic vision correction; at least one treatment zone surrounding the center zone , the at least one treatment zone having a power profile comprising a positive power relative to the center zone, and a transition zone disposed between the center zone and the at least one treatment zone such that the at least one treatment zone , the transition zone, and the center zone form a continuous surface, characterized in that : the at least one treatment zone has a surface shape comprising a portion of a generally toroidal shape, wherein the portion of the generally toroidal shape is derived from a torus after making a slice in the shape of the surface of a right circular cone through the surface of the torus, wherein the principal axis of the cone is coincident with the axis of rotation about which the torus is generated, wherein the at least one treatment zone has an annular configuration sharing a common geometric axis with the center zone , and wherein the at least one treatment zone generates a focal ring, with the locus of each of the infinite focal points on the ring being non-coaxial such that it is displaced from the geometric axis of the center zone . a center zone with a negative power for myopic vision correction; at least one treatment zone surrounding the center zone , the at least one treatment zone having a power profile comprising a positive power relative to the center zone, and a transition zone disposed between the center zone and the at least one treatment zone such that the at least one treatment zone , the transition zone, and the center zone form a continuous surface, characterized in that : the at least one treatment zone has a surface shape comprising a portion of a generally toroidal shape, wherein the portion of the generally toroidal shape is derived from a torus after making a slice in the shape of the surface of a right circular cone through the surface of the torus, wherein the principal axis of the cone is coincident with the axis of rotation about which the torus is generated, wherein the at least one treatment zone has an annular configuration sharing a common geometric axis with the center zone , and wherein the at least one treatment zone generates a focal ring, with the locus of each of the infinite focal points on the ring being non-coaxial such that it is displaced from the geometric axis of the center zone . the at least one treatment zone has a surface shape comprising a portion of a generally toroidal shape, wherein the portion of the generally toroidal shape is derived from a torus after making a slice in the shape of the surface of a right circular cone through the surface of the torus, wherein the principal axis of the cone is coincident with the axis of rotation about which the torus is generated, wherein the at least one treatment zone has an annular configuration sharing a common geometric axis with the center zone , and wherein the at least one treatment zone generates a focal ring, with the locus of each of the infinite focal points on the ring being non-coaxial such that it is displaced from the geometric axis of the center zone . <EOS>
