  • Publication number: 20210055573
    Abstract: An ophthalmic lens comprising: at least one first optical zone with a first axis, the at least one first optical zone being configured such that, in use with an eye, at least a portion of light passing through the at least one first optical zone is refracted to a first focal point on the first axis; and at least one second optical zone configured such that, in use with the eye, at least a portion of light passing through the at least one second optical zone is refracted to one or more focal points positioned off-axis relative to the first focal point and on at least one focal plane different than a focal plane corresponding to the first focal point; wherein the at least one second optical zone is configured such that the light extending beyond the one or more focal points provides extended depth of focus.

  • Patent number: 10502977
    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.

  • Publication number: 20190117062
    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.

  • Publication number: 20180284482
    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.

  • Publication number: 20170235158
    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.
