Lenses incorporate freeform power profiles that at least one of slow, retard or preventing myopia progression. 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 at 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 freeform power profile having substantially equivalent visual performance to a single vision lens, and having a depth of focus and reduced retinal image quality sensitivity that slows, retards, or prevents myopia progression.鏡片結合自由形式屈光率分佈，其減緩、遲滯或預防近視加深之至少一者。一眼用鏡片包括一第一區，其位於該鏡片之一中心處；一第一周圍區域從該中心連續地延伸，該第一周圍區域具有一不同於該中心處的屈光率；及一第二周圍區域，其從該第一周圍區域連續地延伸，並具有一不同於該第一周圍區域的屈光率，從而提供一連續的自由形式屈光率分佈，其具有實質上均等於一單一視力鏡片的視覺性能，並具有延緩、遲滯、或預防近視加深的一聚焦深度及減少的視網膜影像品質敏感度。
