摘要：

PROBLEM TO BE SOLVED: To provide lenses with free-form power profiles that realize at least one of slowing, retardation and prevention of myopia progression.SOLUTION: An ophthalmic lens includes: a first zone at a center of the lens； a first peripheral region continuously extending from the center, the first peripheral region having a different dioptric power than the center； and a second peripheral region continuously extending from the first peripheral region and having a different dioptric power than the first peripheral region, thereby providing a continuous free-form power profile having substantially equivalent visual performance to a single vision lens and having a depth of focus and reduced image quality sensitivity slowing, retarding or preventing myopia progression.SELECTED DRAWING: Figure 6
