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.

Employing diffractive structure to reduce soft contact lens variation

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.

Multifocal lens design and method for preventing and/or slowing myopia progression

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.

Method and apparatus for a variable power opthalmic lens

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.

Lens system for presbyopes with inter-eye vision disparity limits

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.

Method and apparatus for a variable power ophthalmic lens

A toric contact lens utilizes concentric annual rings, a continually varying lens design as a function of distance from the lens center or any other function to create a range of cylinder axis zones on a single lens.

Multi-axis lens design for astigmatism

Contact lenses incorporating asymmetric radial power profiles that increase the radial dioptric power from the center to the margin of the optical zone of the lenses may be utilized to prevent and/or slow myopia progression. The power profiles vary along different meridians.

Asymmetric lens design and method for preventing and/or slowing myopia progression

A family of ophthalmic lenses for correcting presbyopia meets constraints for distance vision, near vision, and disparity and may be designed according to a process that incorporates a merit function accounting for binocular visual performance.

Lens systems for presbyopia

The invention provides methods for designing contact lenses and contact lenses designed according to the method, which lenses provide an improved method for presbyopia correction compared to conventional lenses and methods. It is a discovery of the invention that improved performance and reduced design time can be obtained by using lens pairs that act synergistically to provide the lens wearer with good binocularity and consistent performance in near, intermediate and distance vision.

Lenses for the correction of presbyopia and methods of designing the lenses

Single vision spectacle lens

Designing a progressive addition lens includes using scaled surface powers and/or cylinder powers of base curves to determine a set of power targets, and using these targets to determine a lens design.

Short channel progressive addition lenses

The invention provides methods for designing contact lenses that provides improved efficiency in lens design compared to conventional methods. It is a discovery of the invention that improved performance and reduced design time can be obtained by utilizing a visual performance prediction model as a part of the design process.
