A disposable contacting member molded from an optical wave-guiding material includes a socket adapted to hold a light source and a lens for directing light from the source into an orifice or incision. The lens is on the inner side wall of the contacting member, facing away from the wall of the orifice or incision. The lens is of a sufficiently low profile that is does not obstruct access to the orifice or incision.
