The present disclosure relates to means of managing eye-length disorders, like myopia. The invention includes an apparatus and methods for the prescription, selection, supply and fitting of sets, stocks, or kits of pairs of myopia management spectacles, or spectacle fronts, attachable impermanent auxiliary optical films, or mini optical elements, used in conjunction with standard single vision spectacles, said auxiliary optical films, or optical elements possess one or more meridionally and azimuthally variant power distributions resulting in a delta power and said power distributions are devoid of mirror symmetry, wherein the apparatus and methods are configured to provide a conoid of partial blur, or at least one regional conoid of partial blur, at the retina of the myopic eye to decelerate, ameliorate, control, inhibit, or reduce the rate of myopia progression over time, wherein the method is a prescribed care regimen providing temporal and spatial variation to the directional optical cues or stop signals.

A system includes an electronic contact lens that can detect eye gestures for initiating various actions. The electronic contact lens includes integrated sensors for obtaining sensor measurements characterizing eye motion. The sensor measurements are processed to detect gestures mapped to specific actions such as changing a power state of the electronic contact lens, activating or deactivating a user interface or other feature, or selecting an item from a virtual menu. The eye gestures may involve the user sequentially performing a first saccade quickly followed by a second saccade in an opposite direction from the first saccade.

A method includes: receiving, by a computing device, user input to move content from an augmented reality (AR) interface to a virtual reality (VR) interface; obtaining, by the computing device, security levels of users in a VR environment associated with the VR interface; determining, by the computing device and based on the security levels, which of the users in the VR environment is permitted to see the content; and changing, by the computing device, at least one of the AR interface to the VR interface based on the determining.

An optical article that includes an ophthalmic lens that includes a substrate, a first layer comprising liquid crystals being disposed on at least part of the substrate, and a first and a second electrode made of a conductive material, and a voltage source electrically connected to the first and second electrodes and configured to control an orientation of the liquid crystals depending on the voltage applied. The ophthalmic lens further includes a second layer made of photoconductive material placed between the electrodes, and the optical article further includes a light projector configured to project a light pattern on the second layer of the ophthalmic lens, the second layer being locally conductive when illuminated by the light pattern, the light pattern corresponding to a pattern of refractive index modification to be induced by the liquid crystals of the first layer.

An over-glasses apparatus, configured to be associated with a pair of glasses worn by a user, is disclosed. The apparatus includes a support structure, an eye tracking system, an image sensor, an actuation system of the image sensor, a camera housing, and means for processing and control. Advantageously, the image sensor and the actuation system of the image sensor are within the camera housing, arranged substantially in correspondence with a longitudinally median part of the main body, so that the camera housing intercepts an axis that connects the user's pupils.

Variable-focus lenses are arranged as a lens pair that work on opposite sides of a see-through optical combiner used in a mixed-reality head-mounted display (HMD) device. An eye-side variable-focus lens is configured as a negative lens over an eyebox of the see-through optical combiner to enable virtual-world objects to be set at a close distance. The negative lens is compensated by its conjugate using a real-world-side variable-focus lens configured as a positive lens to provide for an unperturbed see-through experience. For non-presbyopes, the powers of the lenses are perfectly offset. For presbyopes, the lens powers may be mismatched at times to provide simultaneous views of both virtual-world and real-world objects on the display in sharp focus. Responsively an eye tracker indicating that the user is engaged in close viewing, optical power is added to the real-world-side lens to push close real-world objects optically farther away and into sharp focus for the presbyopic user.

An augmented reality device includes an eyeglass frame and a combiner mounted on the eyeglass frame. The combiner includes an inner surface and an outer surface disposed opposite the inner surface. The device further includes an active shutter lens mounted on the combiner and an image projector mounted on the eyeglass frame and configured to project display light to the combiner such that a first portion of the display light is emitted from the inner surface of the combiner and a second portion of the display light is emitted from the outer surface of the combiner. The device additionally includes a processor coupled to the image projector and the active shutter lens. The active shutter lens is configured to shield the display light emitted from the outer surface of the combiner. The combiner is configured to emit ambient light from the inner surface thereof.

A lens including a flexible refractive optic having a fixed refractive index, an electro-active element embedded within the flexible refractive optic, wherein the electro-active element has an alterable refractive index, and a controller electrically connected to the electro-active element wherein when power is applied thereto the refractive index of the electro-active element is altered.
