This is a very unique English optical stereometer instrument, to test visual perception, when any symptoms, unrelated to optical deficits appear, which suggest unsatisfactory eye condition, such as headaches, eye discomfort or feeling of visual strain. The stereometer consists of stereoviewer lenses, slide carrier shaft, stereogram cards, efficiency record pad and an instruction manual. There are 9 stereograms, a complete set. This stereometer was produced in the late 1920’s by Sterosette Ltd Charlton Kings Road London NW5. It was made for general use
