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.

Abstract: Described herein are systems and/or methods for designing a system of contact lenses with interocular refractive disparity (i.e. anisometropia) for presbyopes. An example method may comprise a step of determining a plurality of lenses for inclusion in a system of contact lenses for treating presbyopes. Each of the plurality of lenses may be configured for an optical correction and may have a power profile associated therewith. The plurality of lenses may be grouped based on the optical correction. Each of the lenses in a particular group may have a different power profile. The example method may comprise a step of creating, based at least on the plurality of lenses and an add need, a fit guide. The fit guide may provide an interocular disparity of effective add. The interocular disparity of effective add may be determined by optimizing cyclopean performance across a range accommodative demands and light levels.

Abstract: The present disclosure relates to ophthalmic devices such as ophthalmic lenses. An ophthalmic device may comprise an aspherical first surface and an atoric second surface, disposed opposite the first surface and configured to be disposed adjacent an eye of a user. The second surface may comprise a first conic constant along a first meridian and a second conic constant along a second meridian. The ophthalmic lens may be configured to minimize spherical aberration along the first meridian and the second meridian.

Abstract: A multifocal ophthalmic lens has an optic zone that includes at least one first zone having a dioptric power that satisfies a distance refraction need of a patient; and at least one second zone having a dioptric power that is greater than the dioptric power of the at least first zone. The at least one first zone and the at least one second zone are configured so that 1) an image quality on the retina of the patient is superior to the image quality both in front of the retina and behind the retina, and 2) an image quality in front of the retina of the patient is superior to the image quality behind the retina. The multifocal ophthalmic lens prevents and/or slows myopia progression.

Abstract: This invention discloses methods and apparatus for providing an ophthalmic lens with diffractive/refractive variable optic structures. An energy source is capable of powering the variable optic included within the ophthalmic lens as it may be predetermined. In some embodiments, an ophthalmic lens is cast molded from a silicone hydrogel.

Abstract: A lens system for presbyopes utilizes inter-eye disparity limits to improve vision. The system of lens may be utilized to improve binocular vision when viewing distant, intermediate and near objects by requiring a minimal level of disparity in vision between the eyes wherein the level is not objectionable to the patient. This disparity in vision depends on the lens design for each eye and upon how the lenses are fit in each eye relative to the distance refraction of the patient.

Abstract: Contact lenses incorporate high plus or ADD power profiles that at least one of slow, retard or preventing myopia progression and minimize halo effect. The lens includes a center zone with an ADD power for myopia progression treatment and at least one myopia vision correction power in a peripheral region surrounding the center zone.

Abstract: Ophthalmic lenses for the treatment of presbyopia may be improved to enhance the visual experience of the patient. By adjusting the optical design of presbyopic lenses to account for changes in pupil size due to the degree of myopia or hyperopia, an enhanced visual experience may be achieved independent of the level of ametropia.
