A body-mountable device may include a first layer, a second layer, and an electronic structure. The first layer may include a first topographical feature, while the second layer may include a second topographical feature. The first topographical feature and the second topographical feature may be reciprocally-shaped. The second layer may be mounted on the first layer such that the first topographical feature interfaces with the second topographical feature, thereby mechanically securing the second layer to the first layer. The electronic structure, which may include an antenna, a sensor, and an electronic device, may be embedded in the second layer. In an example in which the body-mountable device is an eye-mountable device, the first layer may be a posterior lens, and the second layer may be an anterior lens.

The present invention discloses methods for manufacturing and programming an energizable Ophthalmic Lens with a programmable Media Insert. In some embodiments, a Media Insert may be programmable to allow for further customization of the energized Ophthalmic Lens. The Media Insert may be programmed prior to or during the manufacturing process. Alternatively, the Media Insert may be programmed after the components have been encapsulated, wherein the programming may occur wirelessly. Accordingly, methods of wirelessly programming the Media Insert may be significant.

This invention discloses methods and apparatus for sealing and encapsulating Components on and within an annular-shaped Multi-Piece Insert. In some embodiments, an ophthalmic Lens is cast molded from a silicone hydrogel and the Component includes a sealed and encapsulated Multi-Piece Insert portion.

An object of the present invention is to provide electronic eyeglass and liquid crystal lens production methods that eliminate the need for forming a liquid crystal injection path in the liquid crystal lens, while making provisions so as to be able to sufficiently maintain a prescribed gap between substrates. The electronic eyeglass and liquid crystal lens production methods includes the steps of placing a sealing agent so as to form a closed planar region on at least one of first and second transparent substrates, dropping a liquid crystal material into an inside space enclosed by the sealing agent, bonding the other of the transparent substrates onto the one transparent substrate on which the liquid crystal material has been dripped, and filling a resin into a space created outside the sealing agent.

The invention relates to a lens (1) for vision correction, wherein the lens (1) is configured to be placed directly on the surface of an eye (2) of a person or to be implanted into an eye (2) of a person, and wherein the lens (1) further comprises: a transparent base element (10) having a back side (12) and a front side (11) facing away from the back side (12), a transparent and elastically expandable membrane (20) connected to said base element (10), wherein said membrane (20) comprises a back side (22) that faces said front side (11) of the base element (10), a ring member (30) connected to said back side (22) of the membrane (20) so that the ring member (30) defines a curvature-adjustable area (23) of the membrane (20), and wherein the lens (1) comprises a lens volume (41) adjacent said curvature-adjustable area (23) of the membrane (20), which lens volume (41) is delimited by the ring member (30), and wherein the lens (1) comprises a reservoir volume (42) adjacent a boundary area (24) of said membrane (20), wherein said two volumes (41, 42) are filled with a transparent liquid (50), and wherein said volumes (41, 42) are fluidly connected or fluidly connectable to each other such that, when the reservoir volume (42) is compressed, liquid (50) residing in the reservoir volume (42) is pressed into the lens volume (41) such that the curvature of said curvature-adjustable area (23) of the membrane (22) increases and the focal length of the lens (1) decreases. Further, the invention relates to a method for manufacturing a contact lens according to the invention.

A spectacle lens is disclosed. The disclosed lens provides a vision correcting area for the correction of a wearer's refractive error. The viewing correction area provides correction for non-conventional refractive error to provide at least a part of the wearer's vision correction. The lens has a prescription based on a wave front analysis of the wearer's eye and the lens can further be modified to fit within an eyeglass frame.
