The present application discloses a system and device for displaying content. The system includes an optical unit that is wearable. The optical unit includes a magnifying lens, a front light, and a display. The front light illuminates the display from the front of the display to be observable by a user via the magnifying lens.

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.

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.

This application concerns a loupe-based wearable device that is enhanced by a mounted visualization aid on the housing body of at least one of the loupe eyepieces, the aid providing a dual light source, a beam splitter, and a camera directed in the same optical path as a user's eyesight such that both visible light and fluorescent dye exciting light can be directed at a site of operation to enhance real time visualization of tissue resection.

The present application discloses a system and device for displaying content. The system includes two optical units. The two optical units are part of the system that is wearable. Each of the two optical units comprises a front lit display. The system includes an adjustable mounting. The adjustable mounting enables a user to adjust a mounting position of the two optical units.

The present invention is an optical assembly featuring an architecture which allows adjustment of both objective lenses and the electronic sensing assemblies in the optical assembly. Electrical connections in the housings of the various subassemblies allow focusing adjustment by rotational and/or translational movement for increased adjustability.

An optical attachment for surgical loupe glasses is disclosed. The optical attachment for surgical loupe glasses includes a visor sized to cover at least a portion of a first carrier lens of the surgical loupe glasses. The optical attachment also includes at least one loupe orienting feature defined by the visor.
