Contact lens and communication system

A contact lens according to an embodiment of the present disclosure includes a lens unit to be placed on an eyeball and a mesh-like or meandering linear communication electrode provided in all or a portion of the lens unit.

Tuneable ophthalmic lens

A tuneable contact lens (100), wherein the contact lens comprises a central region (108). The central region has a circumferential wall and an anterior surface having an external curvature. The contact lens also comprises an inflatable ring (106) arranged around the circumferential wall of the central region, and at least one fluid reservoir (104) in fluid connection with the inflatable ring. The at least one fluid reservoir comprises a pump. When fluid is pumped from the at least one fluid reservoir to the inflatable ring, the inflatable ring inflates and the external curvature of anterior portion of the central region is changed.

Methods and systems for making a lens assembly

Methods and apparatus for making lens assemblies that can be placed on an eye of a person and that include at least one component are described. Generally, a first lens member (100) and a second lens member (200) are formed. The second lens member (200) is transferred to a compliant stage (210). At least one component is placed in contact with one of the lens members (100, 200). The second lens member (200) is placed in contact with the first lens member (100) such that the compliant stage (210) can provide compression to the first and second lens members (100, 200). The second lens member (200) and the first lens member (100) are coupled together to form a lens assembly (10) with the at least one component located between the two lens members (100, 200).

Method of manufacturing hydrogel ophthalmic devices with electronic elements

The present invention provides methods for forming an ophthalmic lens that can include a media insert and/or electronic components. In particular, the present disclosure provides for adhesion promoting functionalization steps for a biocompatible coating to bind a hydrogel material to a plastic surface or electronic component prior to the polymerization of the hydrogel. In some aspects, the media insert can be used to contain energy sources and/or functional electronic components which may be, for example, in a stacked integrated component configuration to permit a generally arcuate shape that can conform to the anterior surface of an eye.

Contact lens for increasing tear production

Described here are devices, systems, and methods for increasing tear production by stimulating the cornea, conjunctiva, and/or subconjunctiva. In some variations, the devices may be in the form of a contact lens. The contact lens may comprise a lens body and a stimulator chip, where the stimulator chip is embedded in the lens body. An external power source wirelessly transmits energy to the stimulator chip, where the stimulator chip may convert the energy to an electric waveform to stimulate the cornea, conjunctiva, and/or subconjunctiva. Stimulation may activate the lacrimal reflex to increase tear production. The devices and systems for increasing tear production may be used in methods of treating dry eye, reducing the symptoms of tired eye, increasing comfort for contact lens wearers, and extending the number of years a contact lens user can wear contacts. Also described are methods of manufacturing a contact lens.

Three-dimensional (3D) printing of electro-active lenses

A method of manufacturing an optic includes disposing electronic circuitry on a substrate. The method also includes depositing a first resin on the first side of the electronic circuitry and curing the first resin to form a first optical segment. The method further includes depositing a second resin on the second side of the electronic circuitry and curing the second resin to form a second optical segment. The first and second optical segments encapsulate the electronic circuitry. The first resin and the second resin can include multiple droplets of resin, thereby reducing mechanical force imposed on the electronic circuitry during printing and allowing conformal contact between the resin and the electronic circuitry. Accordingly, electronic circuitry of smaller dimension can be used to form the electronic eyewear.

Saccade and vergence tracking for distance auto focus adjustment

Lenses and methods for adjusting the focus of a lens include dividing multiple light sensors in a lens into four quadrants. A position of the lens relative to occlusion along a top and bottom edge of the lens is determined based on numbers of bits in respective bit sequences from light sensors in respective regions of the lens. An optimal focal length for the lens is determined based on the position of the lens. The focal length of the lens is adjusted to match the optimal focal length.

Oxygen permeable scleral contact lenses with thick payloads
11150493 · 2021-10-19 · ·

A contact lens has a core that is thick enough to accommodate a payload. The core has a base surface for mounting the contact lens to the sclera of the user's eye. It also provides mechanical integrity to carry the payload. The contact lens also includes an outer covering and an inner covering. Each covering is a thin layer of gas-permeable material shaped to form an air gap between the covering and the core. The two air gaps are connected by an air path that traverses the core. Oxygen from an outside environment passes through the gas-permeable outer covering to reach the outer air gap, through the air path to the inner air gap, and through the gas-permeable inner covering to reach the cornea of the wearer's eye.
