A binocular indirect ophthalmoscope that is adapted to be worn on a wearer's head includes a headband and illumination housing having an illumination source and a viewer module wherein the viewer module is moveable between an in-use and an out-of-use position. A mounting assembly is provided for allowing the viewer module to be pivoted between the in-use and the out-of-use positions and also allows adjustment and locking to the wearer's face in the in-use position. The mounting assembly includes a magnetic securement of the viewer module in both the in-use and out-of-use positions. Part of the magnetic securement operates as an electrical contact to automatically provide power to the illumination source in the in-use position. An optical polarizer provides intensity adjustment of the light energy transmitted to the eye being examined. Preferably the illumination source is a light emitting diode. |
