Abstract: Methods and apparatus are provided for adaptively focusing a lens. In one approach, electromagnetic energy is employed to modify a shape or thickness of a lens such that its refractive power and focal length are modified. In one aspect, a lens embodying adaptive focus features requires low power, and can be adjusted quickly. One or a plurality of electromagnets can be employed to compress or separate end portions of an embedded haptic, the force from which acts to alter the shape of the haptic, thus modifying the refractive power and focal length of a lens.

Abstract: A method and apparatus is disclosed for artificially creating space within a lens such that, when an image is projected from the lens onto the retina of the user, the image appears to be positioned further away than it actually is. This is accomplished by embedding a series of projection tubes on the perimeter of a lens adapted to project an image inward toward the retina of the user. The projection tubes will provide artificial spacing and cause the projected image to seem distant or otherwise positioned further away, creating a more realistic viewpoint for the user.

Abstract: The present invention is a method and apparatus projecting an image or series of images onto the retina. Furthermore, the present invention is neither cumbersome nor obstructive to the user. This is accomplished by embedding an imaging lens on the perimeter of the contact lens adapted to project an image inward toward the center of the contact lens, wherein the projected light will then be redirected onto the retina.

Abstract: A medical device including a pre-defined space such as a geometric shape or void. In one approach, the pre-defined space provides desired rigidity and more comfort for a user. There is also provided an approach which enables engravings and accommodates electronics, mechanical objects, or other rigid or unique shapes to be embedded within a medical device such as a contact lens. When adapted to swellable substrates, the resulting swelled material can leave a gap around a perimeter of embedded structure.

Abstract: The present disclosure provides an elastic electronic circuit adapted to provide three dimensional elasticity while conforming to the curved or angled structures of a swellable medical device, such as a hydrogel or silicone hydrogel contact lens. The elastic electronic circuit can include a first pattern for flexibility in a first dimension, a second pattern for flexibility in a second dimension, and a third pattern for flexibility in a third dimension. Alternatively, the elastic circuit can include a first pattern for flexibility in a first dimension and a second pattern for flexibility in a second dimension. The resulting three-dimensional elasticity enables the use of electronic circuits on soft contact lenses, where manufacture and use will cause the lenses and circuits to swell and shrink. Furthermore, the electronic circuit will not distort the vision correction of the contact lens or otherwise cause discomfort or other negative side effects.
