Provided is a contact lens which incorporates mask lens designs of at least one of slowness, retardation, or prevention of myopia progression. The lens comprises: a first zone on a center of the lens; at least one peripheral zone surrounding the center, having a dioptric power which is different than that on the center; and an opaque mask beginning on a radial distance from the center, thus providing a lens power profile having substantially equivalent foveal vision correction to a single vision lens, and having a depth of focus and reduced retinal image quality sensitivity which slows, retards, or prevents myopia progression. |
