Patent ID: 8734511

Claim:
An ophthalmic lens, comprising: an optic comprising a first surface having a first shape and an opposing second surface having a second shape, the shapes together providing a base optic power; a multifocal refractive profile imposed on at least one of the shapes over a first radial extent, the multifocal refractive profile including a refractive base power of about zero Diopters and a refractive add power between about 1 Diopter and about 3 Diopters; a multifocal diffractive profile imposed on at least one of the shapes over a second radial extent, the multifocal diffractive profile having, for visible light, a primary diffraction order, a secondary diffraction order, and a diffractive add power corresponding to a difference in optical power between the secondary diffraction order and the primary diffraction order, the diffractive add power between about 1 Diopter and about 3 Diopters; an overlap portion between the multifocal refractive profile and the multifocal diffractive profile defining an overlap aperture, the overlap aperture filled by a portion of the multifocal refractive profile that includes both the refractive base power and the refractive add power, the overlap aperture also filled by a portion of the multifocal diffractive profile that includes the primary diffraction order, the secondary diffraction order, and the diffractive add power; wherein the overlap portion has an add region and a base region, the base region of the overlap portion configured for far viewing with the refractive base optic power and the primary diffraction order, the add region of the overlap portion having a combined add power, over the base optic power, suitable for near viewing, the combined add power provided by a combination of the refractive add power and the diffractive add power.
