Abstract: The posterior surface of the contact lens (i.e., the surface that faces inwards towards the eye) includes an oxygen-permeable base. The anterior surface of the contact lens includes a cap that also provides oxygen transport. An intermediate structure is formed by a solidification process, such as casting. Once solidified, this element forms an air chamber between the base and the cap. It may also secure the base and the cap. When the electronic contact lens is worn by the user, the cap, air chamber and base provide an oxygen path from the external environment to the user's cornea. The electronic contact lens also contains an electronics payload, some of which may be encapsulated by the solidified structure during the solidification process.

Abstract: A contact lens having a cap, core, and base forming three layers to allow for the contact lens to be thick enough to accommodate a payload, while ensuring sufficient oxygenation of the wearer's eye. The cap and base are each a thin layer of gas-permeable material, each shaped to form an air gap between them and the core. The two air gaps are connected by air passages that traverse the core. Oxygen from an outside environment passes through the gas-permeable cap to reach the outer air gap, through the air passages to the inner air gap, and through the gas-permeable base to reach the cornea of the wearer's eye. The cap may be annular in form, having a center hole such that the cap does not extend over the central zone of the core, reducing a thickness of the contact lens.

Abstract: A substrate carries electrical components. It is bent into a non-planar shape to fit into a contact lens. For example, the substrate may be constructed from a flexible circuit board. The circuit board has certain regions for mounting electrical components. The flexible circuit board is bent into a three-dimensional shape that fits into the contact lens. The regions used to mount electrical components remain flat.

Abstract: A contact lens has a core thick enough to accommodate a payload. The lens further has outer and inner coverings that cover parts of the core. Each covering is a thin layer of gas-permeable material shaped to form a respective cavity between the covering and the core. Oxygen passes through the outer covering to the outer cavity, through an air path within the core to the inner cavity, and through the inner covering to reach the cornea of the wearer's eye. To increase oxygen flow, a patterned structure is formed at an interface between the core and at least one of the outer and inner covering, comprising supports at which the core and covering contact, and recesses forming the cavity between the core and covering for oxygen flow. The outer and inner coverings may be made from different types of gas-permeable materials having different levels of gas-permeability and brittleness.

Because each recess spans only a short distance between supports, portions of the covering may be made thinner to improve oxygen flow.
