Eyewear including an optical element, a controller, a support structure configured to support the optical element and the controller, light sources coupled to the controller and supported by the support structure, and a diffuser positioned adjacent to the light sources and supported by the support structure, the diffuser including microstructures that diffuse light emitted by the light sources in a radial anisotropic diffusion pattern or a prism-like diffusion pattern.

An eye is illuminated with infrared illumination light from an array of infrared in-field illuminators. A wavefront image of retina-reflected infrared light is generated and an accommodative eye state value is determined based at least in part on the wavefront image.

A user-wearable fluorescence based visualization system comprising a multi-light lamp assembly that provides for the selected output of light using multiple light emitting sources, wherein the outputted light may be tailored to generate response wavelength by the interaction of the emitted light and a tissue illuminated by the emitted light, through the process of fluorescence, and a viewing system that allows a practitioner view the fluorescent light generated by the tissue, and distinguish between healthy and diseased tissues.

An eyewear device, method for use with an eyewear device, and a non-transient computer readable medium for detecting blood sugar levels are disclosed. The eyewear device has a frame including a first rim configured to support a first lens, a second rim configured to support a second lens, and a bridge connecting the first rim to the second rim. The bridge is configured to receive a nose of a user when the eyewear device is worn by the user. Blood sugar levels are detected by monitoring behavior of a pupil of an eye of the user with a sensor, comparing the monitored behavior with known blood sugar level behaviors, identifying a match responsive to the comparison between the monitored behavior and one of the known blood sugar level behaviors corresponding to a particular blood sugar level, and selecting the particular blood sugar level as a blood sugar level of the user.

The invention relates to a method for preventing fatigue of a driver of a motor vehicle (4), with the steps of: acquiring position data (PDM) indicative of the position of the driver, and activating and/or deactivating light glasses (10) worn by the driver depending on an evaluation of the acquired position data (PDM) indicative of the position of the driver.

A hardware mounting system for eyewear including a mounting bracket that is secured to a temple of eyewear by wrapping a stretchable retention band around the temple and aligning two openings in the retention band around a protrusion in the mounting bracket. Either or both of a mounting arm and a spherical rod end can be secured to the mounting bracket. The mounting arm can allow an ear device such as hearing protection to be secured to the eyewear. The spherical rod end allows a device having a socket such as certain illumination devices to be secured to the eyewear.

An opto-electronic module is configured to fit between anterior and posterior surfaces of a contact lens. The opto-electronics module may comprise a plurality of light sources configured to direct a plurality of light beams to a region of the retina away from the fovea and in some embodiments away from the macula. Each of the plurality of light sources may comprises an LED and one or more projection optics. Each of the projection optics can be coupled to an LED with an adhesive prior to placing the opto-electronics module on a layer of contact lens material. The opto-electronics module may comprise a flex PCB with the plurality of light sources, an antenna, a battery, a capacitor and a processor supported on the flex PCB.
