A lighting device comprising a plurality of lighting modules arranged concentrically about an optical axis is disclosed wherein the plurality of lighting modules emit light in at least one of a plurality of wavelength ranges (UV, visible (e.g., blue, green, yellow, orange, red, white, etc.), IR) and are arranged at a non-parallel angle to an optical axis of the lighting device, wherein the emitted light is directed towards a lens system that focuses the light onto a viewing point. A second lighting device is disclosed, wherein the lighting device comprises a plurality of lighting modules arranged concentrically about an inner circumference of the lighting device, wherein the plurality of lighting modules emit light in at least one of a plurality of wavelength ranges (UV, visible (e.g., blue, green, yellow, orange, red, white, etc.), IR) onto a lighting director device that redirects the emitted light toward a lens system that focuses the light onto a viewing point.

An adhesively attached eye mask includes a transparent or semi-transparent plastic eyepiece for positioning over a user's eyes and an integral elongated transparent plastic temple or tab extending rearward from each side edge of the eyepiece for contacting the sides of a user's face. A peripheral edge of the eyepiece can include an adhesive. A face mask can be connected to a lower edge of the eye mask for covering the user's nose and mouth. A peripheral edge of the face mask can include an adhesive. A flexible loop or band can be positioned at each side of the face mask.

A frame includes: a pair of temples; a connecting bar connecting respective ends of the pair of temples; at least one hanging shaft located at a middle of the connecting bar; nose pads fixed to the hanging shaft; a slide attached to the hanging shaft for a sliding movement; a pair of lens-holding frames vertically slidable in front of the connecting bar, the lens-holding frames being each configured to hold vertically arranged upper and lower lenses; and a bridge coupling the lens-holding frames. The bridge is attached at a level lower than a center of the lower lens in each of the lens-holding frames, and the lens-holding frames are slidable for a distance at least corresponding to a distance between a center of the upper lens and the center of the lower lens.

Systems and methods herein describe an actuator control system for intelligent actuated temple attachments on a pair of eyeglasses. The actuator control system receives current measurements corresponding to a length of eyeglass temple attachments on a pair of eyeglasses, and generates predicted measurements for the temple attachments using a machine learning model. The actuator control system transmits the predicted measurements to pneumatic actuators coupled to the eyeglass temple attachments and determines pressure measurements corresponding to a pressure of eyeglass temples against a user of the pair of eyeglasses. Based on the pressure measurements, the actuator control system generates adjusted measurements for the temple attachments and transmits the adjusted measurements to the pneumatic actuators coupled to the eyeglass temple attachments.

Systems and methods herein describe an actuator control system for controlling intelligent actuated temple tips of a pair of eyeglasses. The actuator control system receives a set of measurements corresponding to a length of eyeglass temple tips on a pair of eyeglasses, receives, from a user of the pair of eyeglasses, user feedback corresponding to a position of the eyeglass temple tips, generating a predicted set of measurements for the length of the eyeglass temple tips using a machine learning model, and transmits the predicted set of measurements to pneumatic actuators coupled to the eyeglass temple tips.

A headband for securing eyeglasses on the head of a wearer may include a pair of cords secured to the temple arms of the eyeglasses. Distal ends of the cords may form end loops that fit over the temple arms and movably attach the headband to the temple arms for positioning the eyeglasses on the head of the wearer. Slide connectors may be manipulated to position and tighten the end loops of the pair of cords about the temple arms.

Disclosed is a method and system to construct a head strap for a dental or medical pair of magnifying loupe glasses. Key features of the disclosure are that the head strap is hygienic and very easy to disinfect, while at the same time being easy and quick to adjust and securely attach to the head, and quickly and securely attach to the temples of a standard loupe.

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.

A head strap (120) for medical loupe glasses is provided, comprising two tubes (130, 132) of flexible wipe-clean material and a magnet (134, 136) located on each tube, the magnets (134, 136) being connectable by magnetic forces to effect securement.

A digital loupe system is provided which can include a number of features. In one embodiment, the digital loupe system can include a stereo camera pair and a distance sensor. The system can further include a processor configured to perform a transformation to image signals from the stereo camera pair based on a distance measurement from the distance sensor and from camera calibration information. In some examples, the system can use the depth information and the calibration information to correct for parallax between the cameras to provide a multi-channel image. Ergonomic head mounting systems are also provided. In some implementations, the head mounting systems can be configurable to support the weight of a digital loupe system, including placing one or two oculars in a line of sight with an eye of a user, while improving overall ergonomics, including peripheral vision, comfort, stability, and adjustability. Methods of use are also provided.
