A multifocal ophthalmic lens wherein a first surface of the lens is shaped to form a surface power map and a second surface of the lens is shaped to form a second surface power map. The first surface power map and the second surface power map together form a lens power map. The first surface power map, the second surface power map, or the lens power map comprises a spiral. The spiral has a variation across at least a portion of the lens. Methods of making and using such lenses are also provided.

An ophthalmic lens for myopia control. A first surface of the lens varies across the lens to form a first surface power map. A second surface of the lens varies across the lens to form a second surface power map. Each of the first and second surface power maps comprise a spiral. The spirals formed by the first and second surface power maps twist in opposing directions. Related methods are also described.

Embodiments of the present disclosure describe a biomarker-responsive bifocal contact lens comprising a monovision contact lens having a first focal length and a Fresnel contact lens having a second focal length, wherein the Fresnel contact lens comprises a biomarker-responsive hydrogel, and wherein the Fresnel contact lens is disposed on an outer surface of the monovision contact lens, wherein an optical characteristic of the Fresnel contact lens changes in response to the biomarker concentration in the ocular fluid.

A method and system provide a multifocal ophthalmic device. The ophthalmic lens has an anterior surface, a posterior surface and at least one diffractive structure including a plurality of echelettes. The echelettes have at least one step height of at least one wavelength and not more than two wavelengths in optical path length. The diffractive structure(s) reside on at least one of the anterior surface and the posterior surface. The diffractive structure(s) provide a plurality of focal lengths for the ophthalmic lens.

A ophthalmic lens for inhibiting progression of myopia includes a central zone and an annular zone. The annular zone includes subsurface optical elements formed via laser-induced changes in refractive index of a material forming the annular zone. The subsurface optical elements are configured to modify distribution of light to the peripheral retina of a user so as to inhibit progression of myopia.

A multifocal ophthalmic lens has a surface that varies across at least a portion of the lens to form a surface power map. The surface power map comprises a spiral, with a power that varies substantially periodically both radially outwards from and angularly about an optical axis of the lens. A period of the radial variation is greater than 100 microns and a period of the angular variation is greater than 6 degrees. Methods of making and using the multifocal ophthalmic lens are also described.

A lens for an eye that includes a zone with a first power profile for images received by the retina on the fovea, a zone with a second power profile for images received by the peripheral retina on the nasal side and a zone with a third power profile for images received by the peripheral retina on the temporal side. The first power profile is selected to provide clear or acceptable vision and the second and third power profiles are selected to affect the peripheral image position.

Disclosed are lenses and methods for verifying a lens with an induced aperture. The lenses can have a geometry that, among other things, maintains a centered position about a wearer's eye to prevent more than a permissible amount of movement of the lens relative to the eye. Further disclosed is a method for verifying the power profiles used with the lens, and a lens that can have a single power profile for a wide range of presbyopia.

According to some embodiments, a transparent screen includes a first transparent substrate having a first transparent substrate index of refraction and including a surface relief pattern, a partially reflective coating formed on the surface relief pattern, and a second transparent substrate bonded over the partially reflective coating with an optical adhesive having the first transparent substrate index of refraction.

A method and system provide an ophthalmic device. The ophthalmic device includes an ophthalmic lens having an anterior surface, a posterior surface, at least one diffractive structure and at least one base curvature. The at least one diffractive structure for provides a first spherical aberration for a first focus corresponding to at least a first focal length. The at least one base curvature provides a second spherical aberration for at least a second focus corresponding to at least a second focal length. The first spherical aberration and the second spherical aberration are provided such that the first focus has a first focus spherical aberration and the second focus has a second focus spherical aberration. The first focus spherical aberration is opposite in sign to the second focus spherical aberration.
