An eyeglass-shaped frame includes: a pair of lens-holding frames configured to hold lenses; a bridge connecting the pair of lens-holding frames; a temple foldably attached at a front end side thereof; a nose pad configured to support a nose in contact; movable lens-holding frames configured to be placed oppositely in front of the lens-holding frames; and a vertical movement unit configured to vertically move each of the movable lens-holding frames.

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.

Apparatus and methods are described, including providing a temporary progressive lens (20) that is configured for a subject's temporary use, based upon an initial progressive-lens optical design. The lens is composed of a base lens (22) and an attached additional and removable progressive lens part (24) for test purposes. Data that are indicative of suitability of the optical design for activities that are performed by the subject are received, the data being generated during use of the temporary progressive lens by the subject. Based upon the received data, the optical design for a progressive lens for the subject is optimised, and the optimised optical design in output.

An electronic case for electronic spectacles may include a base comprising a cavity formed therein. A first spectacle retention device may be located within the cavity. The first spectacle retention device may be configured to retain spectacles. An electrical control system may be included. An electrical connector may be configured to couple the electrical control system in electronic communication with the spectacles.

A head mounted display includes a combiner configured to receive display light from a micro-display. The world-facing surface of the combiner has a curvature that corresponds to a user's vision correction prescription. The head mounted display also includes a corrective layer having a second curvature that corresponds to the user's vision correction prescription. The corrective layer is disposed on the eye-facing surface of the combiner such that the focal point of the display light is adjusted for the specific user as the display light exits the combiner towards the user's eye.

Various embodiments of the present invention provide systems, methods, and processes for constructing a contact lens. In one embodiment, a contact lens assembly is provided, comprising: a curved polymer polarizer with an aperture; a lenslet disposed inside the aperture, wherein the lenslet enables imaging near objects; and a filter attached to the lenslet. In further embodiments, a method for fabricating a flexible contact lens is provided, comprising: fabricating an element having an extrusion; providing a front concave mold, wherein the front mold has an intrusion to accommodate the extrusion of the optical element; affixing the extrusion of the optical element to the intrusion of the front mold; attaching a back convex mold to the front concave mold, thereby forming a mold cavity; and filling the mold cavity with a pre-polymerized liquid, whereby upon polymerization, the pre-polymerized liquid forms the flexible contact lens and the optical element is partially encapsulated within the lens.

A method for producing a freeform Fresnel surface having a number of Fresnel facets with a respective Fresnel segment surface and a trailing edge includes the production of the freeform Fresnel surface via machining processing of a starting body based on the construction data for the freeform Fresnel surface. With the aid of the circular cylinder casing surfaces and/or cone casing surfaces, the projection of the edges of the Fresnel facets on the x-y-plane represent circular paths for the creation of the construction data.
