Patent ID: 8876287

Claim:
A method for reducing accommodative error in a patient capable of ocular accommodation, comprising: providing an ophthalmic lens to be disposed relative to a patient's eye capable of ocular accommodation, the ophthalmic lens comprising a vision correction region and a myopic defocus region, wherein the vision correction region has a refractive power to correct the patient's distance visual acuity of the eye and is structured to provide clear vision to the patient at both near and far viewing distances, and the myopic defocus region has a refractive power different than the refractive power of the vision correction region and is structured to provide a myopic defocused image to the patient while viewing at near and at far viewing distances while the patient is provided with clear vision by the vision correction region, wherein the myopic defocus at a near viewing distance differs from the myopic defocus at a far viewing distance by a number of diopters that is greater than or equal to the accommodative error of the patient's eye, wherein a reduced accommodative error of the patient is observed when the ophthalmic lens is disposed relative to the patient's eye to provide vision correction compared to the accommodative error of the patient observed without the ophthalmic lens but fully corrected for distance vision.
