A method of designing a contact lens or other correction for providing presbyopia correction to a patient relies on wavefront aberration measuremen t data for providing a best form correction. Preferably the correction is in t he form of a multifocal translating style alternating vision contact lens or a simultaneous vision style correcting lens. A method for designing a correcti on for improving a person's vision is directed to correcting higher order aberrations in such a manner that a residual amount of the higher-order rotationally symmetric aberration is greater than a residual amount of the higher-order rotationally asymmetric aberration after the correction. A desi gn method according to the invention is directed to correcting asymmetric highe r order aberrations induced by decentering of a multifocal contact lens that h as residual spherical aberration which provides increased depth of field.</SDOA B>
