1. A method for improving vision degradation in a contact lens design to slow, retard or prevent myopia progression in a patient, comprising:
providing a contact lens having a myopia correction zone and an annular treatment zone each concentrically positioned around a central axis of said contact lens, said annular treatment zone surrounding said myopia correction zone;
wherein the myopia correction zone is configured to focus light passing therethrough onto said retina along said central axis; and
wherein the annular treatment zone has a surface shape comprising a portion of a toroid that focuses light passing therethrough in a continuous focal ring that surrounds the central axis the lens, wherein the focal ring is positioned in front of the retina; and
wherein vision degradation of said contact lens is improved as compared to a lens having a myopia correction zone and annular treatment zone that both focus light passing therethrough to focal points along said central axis.
