Ophthalmic device with embedded microcontroller

Abstract: This invention discloses methods and apparatus for providing an ophthalmic lens (200) with a microcontroller (204) and an energy source (208) incorporated within the ophthalmic lens. The energy source is capable of powering the micro-controller included within the ophthalmic lens. In some embodiments, an ophthalmic lens is cast molded from a silicone hydrogel.

Ophthalmic lens media insert

Abstract: This invention discloses methods and apparatus for providing an ophthalmic lens with media including an energy receptor. In some embodiments, the media includes an insert placed in a cavity formed to cast mold an ophthalmic lens from a reactive mixture.

Binder of energized components in an ophthalmic lens

Abstract: The invention discloses methods and apparatus for providing an ophthalmic lens with an energy source incorporated therein.

Apparatus and method for activation of components of an energized ophthalmic lens

Abstract: This present invention provides apparatus and methods for the activation of an energized ophthalmic lens. In some embodiments, the present invention provides for activation and deactivation of one or more components via wireless communication with an activation unit (220) external to the ophthalmic lens (200). In some embodiments, an energized ophthalmic lens contains components which detect external signals, process the detected signal and activate components that change optical characteristics via the control of electrical energy.

Ophthalmic lens assembly having an integrated antenna structure

Abstract: Antennas and antenna systems may be designed and configured for incorporation into mechanical devices, including medical devices, such as ophthalmic devices, including contact lenses. These antennas and antenna systems may be utilized to transmit data from the mechanical device to a receiver, to receive data from a transmitter, and/or to inductively charge an electromechanical cell or the like incorporated into the mechanical device.

Virtual and augmented reality systems and methods

Abstract: Methods of manufacturing a liquid crystal device including depositing a layer of liquid crystal material on a substrate and imprinting a pattern on the layer of liquid crystal material using an imprint template are disclosed. The liquid crystal material can be jet deposited. The imprint template can include surface relief features, Pancharatnam-Berry Phase Effect (PBPE) structures or diffractive structures. The liquid crystal device manufactured by the methods described herein can be used to manipulate light, such as for beam steering, wavefront shaping, separating wavelengths and/or polarizations, and combining different wavelengths and/or polarizations.

Automatic focus improvement for augmented reality displays

Abstract: An augmented reality system provides improved focus of real and virtual objects. A see-through display device includes a variable focus lens a user looks through. A focal region adjustment unit automatically focuses the variable focus lens in a current user focal region. A microdisplay assembly attached to the see-through display device generates a virtual object for display in the user's current focal region by adjusting its focal region. The variable focus lens may also be adjusted to provide one or more zoom features. Visual enhancement of an object may also be provided to improve a user's perception of an object.

Automatic variable virtual focus for augmented reality displays

Abstract: The technology provides an augmented reality display system for displaying a virtual object to be in focus when viewed by a user. In one embodiment, the focal region of the user is tracked, and a virtual object within the user focal region is displayed to appear in the focal region. As the user changes focus between virtual objects, they appear to naturally move in and out of focus as real objects in a physical environment would. The change of focus for the virtual object images is caused by changing a focal region of light processing elements in an optical path of a microdisplay assembly of the augmented reality display system. In some embodiments, a range of focal regions are swept through at a sweep rate by adjusting the elements in the optical path of the microdisplay assembly.

Advanced electro-active optic device

Abstract: Optical devices having a dynamic aperture and/or an apodization mask are provided. The aperture and/or mask may be provided by one or more electro-active elements, and may be used in an ophthalmic device that that is spaced apart from but in optical communication with an intraocular lens, a corneal inlay, a corneal onlay, or a spectacle lens that provide an optical power.

Enhancing an object of interest in a see-through, mixed reality display device

Abstract: Technology is disclosed for enhancing the experience of a user wearing a see-through, near eye mixed reality display device. Based on an arrangement of gaze detection elements on each display optical system for each eye of the display device, a respective gaze vector is determined and a current user focal region is determined based on the gaze vectors. Virtual objects are displayed at their respective focal regions in a user field of view for a natural sight view. Additionally, one or more objects of interest to a user may be identified. The identification may be based on a user intent to interact with the object. For example, the intent may be determined based on a gaze duration. Augmented content may be projected over or next to an object, real or virtual. Additionally, a real or virtual object intended for interaction may be zoomed in or out.
