An apparatus for quantitative assessment of visual contrast sensitivity of a subject comprising a display device, an input device, a control device, and a tangible computer readable medium. In its simplest sense, quantitative assessment profile of visual contrast sensitivity by psychophysical responses is generated on a tangible computer readable medium.
