Embodiments disclosed herein include eyewear that has one or more laminates applied to a lens body. In some embodiments, the lens body is constructed from a substantially rigid material having a curved shape. The lens body can have any desired curvature, including, for example, cylindrical, spherical or toroidal. A laminate can include a substantially flexible substrate and one or more functional layers or coatings applied to the substrate. In addition, one or more functional layers or coatings can be applied directly to the lens body. In certain embodiments, a bonding layer bonds a laminate to a convex and/or concave surface of the lens body. Examples of functional layers or coatings that can be applied to a laminate include anti-reflection coatings, interference stacks, hard coatings, flash mirrors, anti-static coatings, anti-fog coatings, other functional layers, or a combination of functional layers.

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 varifocal ocular lens is disclosed. The varifocal ocular lens is based on a pancake lens having a polarization-folded optical path formed by two reflectors, e.g. one polarization-selective reflector and one partial reflector. By placing at least one of the reflectors onto a flexible deformable membrane, the shape e.g. radius of curvature and/or cylindricity of the reflector(s) may be dynamically changed to vary focal length and/or astigmatism of the ocular lens. Viewer's visual prescription and eye vergence may be dynamically and/or statically accommodated by the varifocal lens.

A head-mounted apparatus include an eyepiece that include a variable dimming assembly and a frame mounting the eyepiece so that a user side of the eyepiece faces a towards a user and a world side of the eyepiece opposite the first side faces away from the user. The dynamic dimming assembly selectively modulates an intensity of light transmitted parallel to an optical axis from the world side to the user side during operation. The dynamic dimming assembly includes a variable birefringence cell having multiple pixels each having an independently variable birefringence, a first linear polarizer arranged on the user side of the variable birefringence cell, the first linear polarizer being configured to transmit light propagating parallel to the optical axis linearly polarized along a pass axis of the first linear polarizer orthogonal to the optical axis, a quarter wave plate arranged between the variable birefringence cell and the first linear polarizer, a fast axis of the quarter wave plate being arranged relative to the pass axis of the first linear polarizer to transform linearly polarized light transmitted by the first linear polarizer into circularly polarized light, and a second linear polarizer on the world side of the variable birefringence cell.

A method for determining an electronic spectacle frame element of a spectacle frame, including providing electronic element data relating to an electronic element to be embodied in a spectacle frame element; providing predetermined spectacle frame element data related to at least one geometrical parameter of a predetermined spectacle frame element, corresponding to the wearer demand; defining a working electronic spectacle frame element including a working spectacle frame element and an electronic element embodied in the working spectacle frame element based on the electronic element data, modifying the working electronic spectacle frame element, and determining the electronic spectacle frame element by repeating the modifying step so as to minimize the difference between the geometrical parameters of the predetermined spectacle frame element and the working spectacle frame element.

Methods of manufacturing eyeglasses are provided. The method may include providing a blank (63) with an outcoupling element (25) and machining the blank to provide a light receiving surface based on the at least one physiological parameter. Corresponding blanks and sets of eyeglasses are also provided.

A lens specification for multiple lens layers of a lens structure is generated by one or more processors. A multifocal correction (MFC) component is assigned to at least one lens layer of the multiple lens layers. Parameters are generated for a display optics (DO) lens layer comprising an augmented reality (AR) display, the DO lens layer having a first side for facing an eye of the user and a second side for facing away from the eye of the user. Parameters are generated for one or more eye side (ES) lens layers of the multiple lens layers to be disposed adjacent to the first side of the DO lens layer, and for one or more world side (WS) lens layers to be disposed adjacent to the second side of the DO lens layer. The generated lens specification is provided for use in production of the lens structure for the user.

A wearable heads-up display includes a power source, laser sources, and a lightguide. A photodetector is positioned to detect an intensity of a test light emitted at a perimeter of the lightguide from an optical path within the lightguide. A laser safety circuit provides a control to reduce or shut off a supply of electrical power from the power source to the laser sources in response to an output signal from the photodetector indicating that the detected intensity is below a threshold.

An anamorphic optical system and a display apparatus including the same are disclosed. The anamorphic optical system includes an illumination system having astigmatism, and first and second correction lenses that are provided to have tangential power and sagittal power respectively and correct the astigmatism in the illumination system. The first and second correction lenses are provided in which a difference between a distance from the first correction lens to a tangential image formed by the first correction lens and a distance from the second correction lens to a sagittal image formed by the second correction lens corresponds to a distance between the first correction lens and the second correction lenses, and at least one of the first correction lens and the second correction lens has an asymmetric stop to form the tangential image and the sagittal image on the same surface.

Provided is a selectively filtered vision protection system for defense against aircraft laser threats. The system comprises a viewing device having a frame supporting a transparent viewing surface. The frame is configured to be positioned on the face of a user such that the user may see through the viewing surface. A selective filter is positioned adjacent to the viewing surface such that the angle of the field of view of the user is regulated in at least one orthogonal plane. The viewing angle is selected to prevent light transmitted from a light source, located outside of the viewing angle, from being viewed by the user. The selective filter is configured to operate in a first mode for transmitting light unrestricted through the viewing surface, and a second mode to regulate the angle of the field of view of the user in at least one orthogonal plane.
