Embodiment Construction
[0072] The following description includes sample systems, methods, and devices embodying various elements of the disclosure. It should be understood, however, that the described disclosure may be practiced in a variety of forms in addition to those described herein.
[0073]This disclosure describes systems, devices, and techniques related to ophthalmic lenses (also referred to herein as "ophthalmic devices" or variations thereof). The ophthalmic lens may have a metasurface array defining, including, or otherwise associated with the metasurface features of the ophthalmic lens. The metasurface features can be specifically tuned to modify the optical properties of the lens without necessarily relying on the geometry of the lens to produce the desired optical effect. For example, metasurface features may be configured across the body of the lens to reduce the glare properties of the lens, including contributing to halo reduction and / or contrast enhancement, among other optical p...

Abstract
Ophthalmic lenses and methods of making the same are disclosed. An ophthalmic lens includes metasurface features that define an array of metasurfaces on a lens body. The metasurface array may be adjusted to modify an optical property of the ophthalmic lens, such as glare reduction, using an arrangement of metasurface build elements sized according to the optical wavelength, including smaller than the optical wavelength. The ophthalmic lens may be subjected to physical manipulation, including winding or other folding during the installation process, and thus modified optical properties caused by the array of metasurfaces may be maintained after such manipulation. Ophthalmic lenses may be formed using a molding process in which the array of metasurfaces is associated with a non-solid material and formed into a lens shape with the material.
Description
[0001] Cross References to Related Applications [0002] This patent application claims priority to U.S. Provisional Application No. 62 / 879,834, filed July 29, 2019, and entitled "SYSTEMS AND METHODS FORFORMING OPHTHALMIC LENS INCLUDING META OPTICS FIELD," the disclosure of which is incorporated by reference Incorporated into this article as a whole. technical field [0003] The described embodiments relate generally to ophthalmic devices, and more particularly to systems and techniques for modifying optical properties of lenses using metasurface features. Background technique [0004] Ophthalmic devices may be used to provide vision correction to users, treat various diseases, and the like. In many conventional applications, the geometry of the device itself is used to induce the desired optical properties of the lens body associated with the treatment, for example via refraction. Many conventional systems have significant disadvantages, as the physical properties and siz...
