Abstract: An ophthalmic lens comprising a power profile that incorporates a plurality of lens powers wherein some of the lens powers are designed to correct for distance refractive error of the eye and other powers are either approximately relatively positive or approximately relatively negative to the distance refractive error power or both and the ophthalmic lens is designed to provide a through focus retinal image quality curve with the peak positioned in front of the retinal image plane for all pupils of about 4 to 6 mms in diameter on a model eye with zero aberrations. The through focus retinal image quality peak being similarly positioned with respect to the pupils in said range.

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 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: Methods and systems for tracking ocular vergence movements of an eye of a person are described. The methods and systems involve placement of flexible/stretchable skin-like electrodes on a person's head and recording the biopotential or electrooculogram of the person as the eye or eyes move to different focal positions, such as near distances, intermediate distances, and far distances. A data acquisition unit can record the electrooculogram and transmit the electrooculogram data to a computer for classification or for further processing. The data can be used with ophthalmic devices to provide a visual change for a person with the ophthalmic device.
