The disclosure describes an electrowetting contact lens comprising including an electrowetting cell. The cell includes first and second optical windows that form a sealed enclosure. A first electrode is formed on the first optical window, and a second electrode is formed on the second optical window. The first and second electrodes include an electrically conductive layer, and the first electrode includes at least one dielectric layer sandwiched between the relevant optical window and the at least one dielectric layer. Oil and saline layers are positioned in the sealed enclosure so that the oil is in contact with one electrode and the saline is in contact with the other electrode. A protective coating encloses the electrowetting cell, and a contact lens material encloses the sealing material. Other embodiments are disclosed and claimed.

An eye-mountable contact lens is provided that includes electronics encapsulated within a rigid, gas-permeable polymeric material. The rigid, gas-permeable polymeric material can be mountable to a corneal surface of an eye or can be disposed on or within a flexible polymeric material that is mountable to the corneal surface of the eye. The rigid, gas-permeable polymeric material can provide structural rigidity and protection to the electronics and/or can allow for long-term dry storage of a chemical sensor of the electronics. The rigid, gas-permeable polymeric materials of the provided eye-mountable devices can be formed by curing a precursor material on or around the electronics and subsequently removing portions of the polymeric material formed by the curing, e.g., to form a rigid, gas-permeable contact lens that at least partially encapsulates the electronics and that has a curved shape that is able to be mounted to a corneal surface of an eye.

An edge of a lens blank an eyeglass lens having a shaped edge is measured at a plurality of peripherally offset measuring positions and respective control values are generated corresponding thereto and supplied to an applicator. This applicator applies a hardenable material in liquid form to the edge of the eyeglass lens and is controlled such that an amount and/or position of the material is applied at the measuring positions according to the respective control values in a controlled manner. The hardenable material is chemically or radiation-cured to form on the edge of the lens a functional layer that has an optical, magnetic, electric, or electronic function.

The invention relates to a method of manufacturing an optical lens (12) comprising at least one electronic component (14, 16), the method comprising: providing (S2) a mechanical reference system on an optical lens blank, the optical lens blank being configured to be processed to form the optical lens; providing (S4) edging data configured to be used to edge the optical lens blank to form the optical lens; embedding (S6) the at least one electronic component in the optical lens based on edging data and on the mechanical reference system.

An eye-mountable device is provided that includes electronics encapsulated within a rigid, gas-permeable polymeric material. The eye-mountable device includes an electroactive lens that can be operated to control an overall optical power of the eye-mountable device to restore an amount of visual accommodation of an eye to which the device is mounted. A method for fabricating the eye-mountable device is provided that includes applying an adhesive to secure lenses of the electroactive lens together and to maintain an amount of liquid crystal in the space between the lenses. The rigid, gas-permeable polymeric material can then be formed around the electroactive lens, electronics, or other elements of the eye-mountable device. The rigid, gas-permeable polymeric material can be mountable to a corneal surface of an eye or can be disposed on or within a soft polymeric material that is mountable to the corneal surface of the eye.

A contact lens includes a lens material and a sensor coupled to the lens material. The sensor is configured to sense a measurable characteristic used to determine an intraocular pressure of an eye to which the contact lens is applied. The sensor can include a variable capacitance sensor configured to change capacitance in response to a mechanical strain of the lens material. The intraocular pressure of the eye can then be correlated to the mechanical strain of the lens material.

A contact lens system includes a shared antenna electrode, an accommodation actuator to provide variable optical power, and a controller coupled to the accommodation actuator and the shared antenna electrode. The controller including logic for arbitrating access to the shared antenna electrode between an impedance sensor and a communication circuit; selectively establishing an oscillator with the impedance sensor and the shared antenna electrode; correlating an oscillation condition of the oscillator to an accommodation setting; and adjusting the variable optical power of the accommodation actuator based upon the accommodation setting. An impedance across the shared antenna electrode varies based upon an amount an eyelid overlaps the contact lens system when the contact lens system is worn on an eye.
