The present invention provides methods for forming an ophthalmic lens that can include a media insert and/or electronic components. In particular, the present disclosure provides for adhesion promoting functionalization steps for a biocompatible coating to bind a hydrogel material to a plastic surface or electronic component prior to the polymerization of the hydrogel. In some aspects, the media insert can be used to contain energy sources and/or functional electronic components which may be, for example, in a stacked integrated component configuration to permit a generally arcuate shape that can conform to the anterior surface of an eye.

An eye-mountable device (EMD) includes a lens enclosure, liquid crystal material, first and second electrodes, a substrate, and a controller. The lens enclosure includes a first encapsulation layer and a second encapsulation layer sealed to the first encapsulation layer. The liquid crystal material is disposed across a central region of the lens enclosure. The first electrode is disposed within the lens enclosure between the first encapsulation layer and the liquid crystal material. The second electrode is disposed within the lens enclosure between the second encapsulation layer and the liquid crystal material. The substrate is disposed within the lens enclosure between the first and second encapsulation layers. The controller is disposed on the substrate and electrically coupled to the first and second electrodes to apply a voltage across the liquid crystal material.

Ophthalmic lens molds made from at least one vinyl alcohol copolymers with high amorphous content, ophthalmic lenses including silicone hydrogel contact lenses formed using these molds, packaged ophthalmic lenses present in a solution comprising the at least one vinyl alcohol copolymer with high amorphous content, and related methods are described. The methods of manufacturing ophthalmic lenses can use wet demolding, delensing or demolding and delensing processes involving dissolving the molds in water or an aqueous solution.

The present invention uses 3 dimensional printer technologies to create specialized contact lenses by building up optical features onto a shell of a contact lens. In this context, a shell is a curved disk with the same radius of curvature on the front and back surface providing a spherical base curve to fit the cornea and no optical power on the front curve. Starting with such a shell, the present invention provides that the 3-dimensional printer is utilized to build optical features on to the front surface.

One embodiment of an ocular lens includes a lens body configured to contact an eye where the lens body has an optic zone shaped to direct central light towards a central focal point of a central region of a retina of the eye. At least one optic feature of the lens body has a characteristic that directs peripheral light off axis into the eye away from the central region of the retina. Another has embodiment of an ocular lens at least one isolated feature of the lens body that has a characteristic of directing peripheral light off axis into the eye away from the central region of the retina. Methods of making contact lenses include forming the features during the manufacturing process.

The present disclosure relates to devices and methods for the production of optical devices and other objects requiring precise surfaces and/or complex geometries. Mold sections with optically precise surfaces and/or surface features having labyrinthine geometries prepared using additive manufacturing processes are provided. Methods of preparing mold sections by applying mold inserts by additive manufacturing processes are also provided. A mold insert with an optically precise surface and/or surface features with a labyrinthine geometry may be manufactured using an additive manufacturing process without any need for further tooling.

Techniques and mechanisms for providing an eye-mountable device including an accommodation actuator. In an embodiment, fabrication of the eye-mountable device includes sealing layers of enclosure material to form a lens enclosure comprising a pinch-off region where the layers of enclosure material physically contact one another. The accommodation actuator includes a liquid crystal layer disposed between the layers of enclosure material in a central region around which the pinch-off region extends. In another embodiment, electrodes are disposed in the central region each between the liquid crystal layer and a respective one of the layers of enclosure material. The liquid crystal layer isolates the electrodes from one another in the central region.
