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.

An optical element (e.g., a lens) may include an optically uniaxial or optically biaxial organic solid, for example, an organic molecular solid. The direction of a maximum refractive index of the organic solid may be aligned substantially orthogonal to an optical axis of the lens. In some examples, a device may include a display and an optical configuration configured to receive light from the display and direct the light to a remote view location. In some examples, the optical configuration may comprise a lens and at least one surface of the lens may include a plurality of facets, for example, to form a Fresnel lens.

The disclosure generally describes methods, systems and products relating to the development and manufacture of scleral contact lenses. A number of dimensions for the scleral lens is generated based on control points and attendant curvature parameters. Any change to one or more of the curve parameters imparts an improved anterior and posterior surface of the scleral lens and associated thickness, while undesired modifications to control points and other curve parameters remain static inasmuch as the sagittal depth component is an input parameter of the present disclosure.
