Abstract: An ophthalmic lens configured to correct and/or treat at least one condition of the eye (e.g., presbyopia, myopia, hyperopia, astigmatism, binocular vision disorders and/or visual fatigue syndrome) comprising: a central optical zone; a peripheral optical zone; a base power profile; and at least one feature selected to modify the base power profile and to form one or more off-axis focal points in front of, on, and/or behind a retinal image plane and reduce a focal point energy level at one or more image planes; wherein the at least one feature may be located on a front surface and/or a back surface of at least one of the central optical zone and the peripheral optical zone.

Abstract: An ophthalmic lens for myopia control comprising patterns or masks which block and/or attenuate light (e.g., by amplitude modulation). The amplitude modulation may be binary, for example, where zero amplitude means absorption or blocking of light and a value of one means that light may be transmitted through the lens without change (e.g., without significant change). Alternatively, in some embodiments, the amplitude modulation may not be binary.

Abstract: An ophthalmic lens comprising a power profile that incorporates a plurality of lens powers wherein some of the lens powers are designed to correct for distance refractive error of the eye and other powers are either approximately relatively positive or approximately relatively negative to the distance refractive error power or both and the ophthalmic lens is designed to provide a through focus retinal image quality curve with the peak positioned in front of the retinal image plane for all pupils of about 4 to 6 mms in diameter on a model eye with zero aberrations. The through focus retinal image quality peak being similarly positioned with respect to the pupils in said range.

Abstract: An ophthalmic lens comprising a base lens configured to direct light to a first image plane; and a plurality of light modulating cells. One or more of the plurality of light modulating cells refract light to a second image plane different from the first image plane and/or one or more of a plurality of light modulating cells refract light to a third image plane different from the first and second image planes. In some embodiments, at least one of the plurality of light modulating cells is configured to refract light to at least two (e.g., 2, 3, or 4) image planes, different from the first image plane.

Abstract: An ophthalmic lens comprising a front surface; a back surface; and one or more geometrically defined shapes and/or contour optical elements formed by changing the curvature of at least one of the front surface of the ophthalmic lens and/or a back surface of the ophthalmic lens; wherein the one or more geometrically defined shapes and/or contour optical elements on the surface of the ophthalmic lens are formed by applying a function to one or more parameters of the ophthalmic lens in a predefined region of the ophthalmic lens and in a predefined direction.

Abstract: An ophthalmic lens for treating myopia comprising: a base lens with a front surface, a back surface, and a first power profile selected to correct or substantially correct for a distance refractive error of the eye; one or more myopia control elements on at least one of the front and back surfaces of the lens; a first viewing region having a dimension selected based, at least in part, on a concentration of a pharmaceutical agent for use in conjunction with an ophthalmic lens, the first viewing region being configured to minimize, reduce and/or eliminate vision disturbances for distance vision; and a second viewing region comprising a power profile that is relatively more positive compared to the first viewing region; wherein at least one of the size of the second viewing region and the relatively more positive power of the second viewing region is selected based, at least in part, on the concentration of the pharmaceutical agent.

Abstract: An ophthalmic lens comprising: at least one first optical zone with a first axis, the at least one first optical zone being configured such that, in use with an eye, at least a portion of light passing through the at least one first optical zone is refracted to a first focal point on the first axis; and at least one second optical zone configured such that, in use with the eye, at least a portion of light passing through the at least one second optical zone is refracted to one or more focal points positioned off-axis relative to the first focal point and on at least one focal plane different than a focal plane corresponding to the first focal point; wherein the at least one second optical zone is configured such that the light extending beyond the one or more focal points provides extended depth of focus.
