Employing diffractive structure to reduce soft contact lens variation

Abstract:

An ophthalmic lens may comprise a main body comprising an optic zone and a peripheral zone disposed adjacent the optic zone, wherein the optic zone comprises a refractive structure that exhibits a first optical power and a diffractive structure disposed within the optic zone, wherein the diffractive structure exhibits a second optical power, wherein the ophthalmic lens is associated with a first target SKU optical power.
