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 lengths of bit sequences from light sensors in each of the four quadrants. 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.

This invention discloses a device comprising multiple functional layers formed on substrates, wherein at least one functional layer comprises an electrical energy source. In some embodiments, the present invention includes a component for incorporation into ophthalmic lenses that has been formed by the stacking of multiple functionalized layers.

An electronic device can comprise a first electronic module; a second electronic module; and a hermetic electric interconnect to hermetically couple them. The hermetic electric interconnect can comprise a bottom metal layer; a bottom insulating layer, deposited on the bottom metal layer to insulate the bottom metal layer; an interconnect metal layer, deposited on the bottom insulating layer, and deposited to form a bottom sealing ring; and patterned to form electrical connections between contact pads, and to form a middle sealing ring; a patterned top insulating layer, deposited on the interconnect metal layer to insulate the interconnect metal layer; and patterned to form feedthrough holes; and a top metal layer, deposited on the top insulating layer to start forming contacts by filling the feedthrough holes; and patterned to complete forming contacts through the feedthrough holes, to form a separate barrier layer, and to complete forming the top sealing ring.

An ophthalmic lens comprising a stacked integrated component device can provide various functionality. The stacked integrated component device may contain an energy source capable of powering an electrical component incorporated into the lens.

A smart contact lens includes a contact lens, a nanostructures layer, a first sensor, a connector, and a smart module. The nanostructures layer may be anti-bacterial. The smart contact lens may be worn on an eye or may be implanted within an eye. The nanostructures layer is fabricated by depositing a colloidal dispersion onto an electrostatically-coated substrate. The colloidal dispersion is then removed and nanoholes are etched. The electrostatic coating is removed and a biocompatible material is spin-coated onto the substrate. Upon removal, a quasi-randomly distributed nanostructures layer forms.
