A vision screening device may include a housing having an emission surface and enclose a first emitter with one or more light sources. The vision screening device may include a reflector connected to the first emitter and partially surrounding the one or more light sources, the reflector configured to reflect from the one or more light sources out of the emission surface. The vision screening device further includes a polarizer coupled to the reflector at an output side of the reflector and a beam splitter positioned between the polarizer and the emission surface such that light from the reflector passes through the beam splitter and reflected light received through the emission surface is directed at an angle relative to an incident angle of the reflected light.
