A user-wearable illumination assembly comprises a mounting fixture that is adapted to be coupled to a user-wearable device, such as eyeglasses, goggles, face masks, helmets, or other devices. A light guide has a first end that can be coupled to a light source, and a second end coupled to a lens housing that is in turn coupled to the mounting fixture. An optical lens in the lens housing cooperates with the light guide to project light from the light source through the lens. In one embodiment, the lens has a substantially spherical surface facing the second end of the light guide and an aspheric surface facing away from the second end of the light guide. In another embodiment, the mounting fixture comprises articulating portions to permit independent or simultaneous adjustment of the lens housing to direct projected light in a desired direction.
