Abstract: A multi-function light device includes a base having two opposed main surfaces and an aperture extending through the main surfaces. A first magnifying lens is mounted on the base and aligned with the aperture to enable magnified viewing through the base member from the one main surface to the other main surface. An energizable source of blacklight blue light and an energizable source of white light are mounted on the other main surface and disposed about the first magnifying lens. The light sources are connectable to an energy source. The device is particularly suitable to enable lice detection on a patient.
