An ophthalmic lens system for reducing the risk of progression of a myopic eye by selectively maintaining, inducing or creating asymmetry of the peripheral retinal profile for the eye. A method for reducing the risk of progression of myopia comprising determining the magnitude of asymmetry of the on-axis/off-axis refractive error profile or eye length profile of the eye and providing an ophthalmic lens system that corrects for and provides acceptable on-axis vision and simultaneously controls the position of the off-axis refractive error profile or eye length profile such that resultant profile of the eye is asymmetric.

A device includes a light source configured to emit an image light. The device also includes an optical assembly configured to direct the image light to an eye-box of the device. The optical assembly includes a first optical element portion configured to focus a first portion of the image light propagating through the first optical element portion. The optical assembly also includes a second optical element portion configured to focus a second portion of the image light propagating through the second optical element portion. The second optical element portion includes a liquid crystal (“LC”) lens having an adjustable optical power.

A lens specification for multiple lens layers of a lens structure is generated by one or more processors. A multifocal correction (MFC) component is assigned to at least one lens layer of the multiple lens layers. Parameters are generated for a display optics (DO) lens layer comprising an augmented reality (AR) display, the DO lens layer having a first side for facing an eye of the user and a second side for facing away from the eye of the user. Parameters are generated for one or more eye side (ES) lens layers of the multiple lens layers to be disposed adjacent to the first side of the DO lens layer, and for one or more world side (WS) lens layers to be disposed adjacent to the second side of the DO lens layer. The generated lens specification is provided for use in production of the lens structure for the user.

A method for determining an ophthalmic lens adapted to a wearer, the method including: receiving wearer data including at least the ophthalmic prescription of the wearer; receiving a set of object points associated with target optical performances based on the wearer data; determining an ophthalmic lens adapted to the wearer, the ophthalmic lens providing optical performances, for light rays propagating from the set of object points to the center of rotation of the eye of the wearer passing through the ophthalmic lens, the closest to the target optical performances.

A metalens includes one or more regions of nanostructures. A first region of nanostructures directs a first field of view (FOV) of light incident on the first region of nanostructures to a first region of an image plane. A second region of nanostructures directs a second FOV of light incident on the second region of nanostructures to a second region of the image plane in which the second FOV is different from the first FOV, and the second region of the image plane is different from the first region of the image plane. A third region of nanostructures directs a third FOV of light to a third region of the image plane, in which the third FOV is different from the first FOV and the second FOV, and the third region of the image plane is different from the first region and the second region of the image plane.

The stabilized contact lens methods and apparatus disclosed herein provide improved stabilization of a contact lens placed on a cornea of an eye. The contact lens comprises stabilization zones that allow the lens to repeatedly and consistently orient on the cornea such that a sensing zone located on the lower portion of the lens is located inferiorly to engage the lower eyelid. The stabilized contact lens can provide a lower pressure sensing zone with decreased thickness for pressure or other sensing related to the lower eyelid. The decreased thickness has the advantage of improving coupling between forces from an eyelid and a lower chamber of a fluidic module. The improved coupling allows increased amounts of fluid to move between the lower chamber and an upper optical chamber coupled to the lower chamber, such that the upper chamber can increase curvature and optical power in response to pressures of the eyelid.

A computer-implemented method for calculating or assessing a spectacles lens for an eye of a spectacles wearer. The method includes (a) providing an association of at least one imaging property or aberration of a spectacle lens system with the vision of the spectacles wearer, or of an average spectacles wearer, when observing an object through the spectacles lens system; (b) determining or prescribing a target function for the spectacles lens to be calculated or assessed, in which the association from step (a) is to be evaluated; and (c) calculating or assessing the spectacles lens to be calculated or assessed by evaluating the target function, wherein the target function is evaluated at least once.

An ophthalmic multifocal lens, and a method of manufacturing same, at least comprising focal points for near, intermediate and far vision. The lens comprises a light transmissive lens body providing a refractive focal point, and a periodic light transmissive diffraction grating, extending concentrically over at least part of a surface of the lens body and providing a set of diffractive focal points. The diffraction grating is designed to operate as an optical wave splitter, the refractive focal point providing the focal point for intermediate vision and the diffractive focal points providing the focal points for near and far vision. The diffraction grating has an optical transfer function comprising a continuous periodic phase profile function having an argument modulated as a function of the radial distance (r) to the optical axis of the lens body, thereby tuning the light distribution in the focal points.
