A smart glasses viewing area management system and processes for managing content display in smart glasses according to a relationship between a content viewing area and a field of view of a user are disclosed. The smart glasses viewing area management system enables caption glasses to define a viewing cone area for multiple devices with methodology to turn content on or off when a user chooses to focus on an object(s). When a person is watching TV and turns to talk with the person next to them the captions will stop displaying on the caption glasses.

An optical system intended to be worn in front of an eye of a wearer including an optical lens having at least a control point and an optical device that has a plurality of optical elements, the optical device being attached on a surface of the optical lens or encapsulated into the optical lens, wherein each optical element has simultaneously two different optical functions, and the optical device and the optical lens are configured so that the absolute value of the difference between a measured optical power at the control point of the optical system and the optical power corresponding to the prescription for said eye of the person is smaller than or equal to 0.12 diopter.

The present disclosure is directed to devices and/or systems of modifying the incoming light through spectacle lenses that utilise at least one auxiliary or regional optical element, to provide extension or elongation of the depth of focus for a myopic eye. The disclosure relates to methods of correcting myopia and controlling or reducing the rate of myopia progression utilising extension of the depth of focus provided by the at least one auxiliary or regional optical element configured within, or in conjunction, combination, or juxtaposition with spectacle lenses. This disclosure relates to the use of an axicon, a light sword element, or a peacock eye element within the regional optical element or a sub-lens. This disclosure also relates to the use of a plurality of axicons, light sword elements or peacock eye elements configured within, or in conjunction, combination, or juxtaposition with spectacle lenses.

A tuneable contact lens (100), wherein the contact lens comprises a central region (108). The central region has a circumferential wall and an anterior surface having an external curvature. The contact lens also comprises an inflatable ring (106) arranged around the circumferential wall of the central region, and at least one fluid reservoir (104) in fluid connection with the inflatable ring. The at least one fluid reservoir comprises a pump. When fluid is pumped from the at least one fluid reservoir to the inflatable ring, the inflatable ring inflates and the external curvature of anterior portion of the central region is changed.

The present disclosure is directed generally to a lens that provides a stop signal to a myopic eye, over a substantial portion of the spectacle lens that the viewer is using. The present disclosure is directed to devices, methods and/or systems of imposing a stop signal to eye growth, using a spectacle lens in conjunction with a micro lenslet array. The present disclosure is also directed to devices, methods and/or systems of modifying incoming light through spectacle lenses that utilizes chromatic cues to decelerate the rate of myopia progression. The present disclosure is directed to devices, methods and/or systems of imposing a stop signal to eye growth, using a spectacle lens in conjunction with a refractive optical element and/or diffractive optical element that offer conflicting or contradictory optical signals at a wavelength between 510 nm and 610 nm.

A spectacle lens has, starting from the object-sided front surface of the spectacle lens to the opposite rear-side of the spectacle lens, at least a) one component A including at least one functional layer F.sub.A and/or an ultrathin glass, b) one component B including at least one polymer material and, c) one component C, including at least one functional layer F and/or an ultrathin glass. A method, in particular a 3D printing method, for producing the spectacle lens is also disclosed.

Various embodiments of the present invention provide for systems and apparatus directed toward using a contact lens and deflection optics to process display information and non-display information. In one embodiment of the invention, a display panel assembly is provided, comprising: a transparent substrate that permits light to pass through substantially undistorted; a reflector disposed on the transparent substrate; and a display panel aimed toward the reflector and substantially away from a human visual system, wherein the reflector reflects light emitted from the display panel toward the human visual system. The reflector may comprise a narrow band reflector or a polarization reflector.

An eyewear system including an eyewear frame and an application module. The eyewear frame including a docking station, and an electronic connector including a first set of preconfigured application connection points. The application module adapted to be mounted to the docking station, and including an electronic device configured to perform a function, and a second set of preconfigured application connection points corresponding to at least some of the first set of preconfigured application connection points. The second set of preconfigured application connection points including at least two different sub-function connections used to support the function of the electronic device.

Provided are an apparatus and method for measuring a visual acuity (VA) by using a focus-tunable lens. The apparatus includes a display engine, an image combiner, a focus-tunable lens provided on a path of the light guided by the image combiner, an input device, and a processor configured to control the focus-tunable lens to assign different first and second optical powers to first and second lens regions, respectively, on a lens surface of the focus-tunable lens, control the display engine to display a VA measuring image through first and second output regions of the image combiner, control the input device to receive a user's input with respect to the VA measuring image, specify one optical power of the first and second optical powers based on the user's input, and determine a VA of a user based on the specified optical power.

A distortion profile is based on user lens data and a selected optical-mechanical profile of a selected head mounted device. The user lens data is associated with prescription lenses worn by the user. A prescription optical layer is fabricated based on the distortion profile for the selected head mounted device.
