A method is presented to address quantitative assessment of visual contrast sensitivity in a subject, where the method comprises the steps of: (1) presenting at least one scene to the subject on a display, the scene comprising a plurality of elements and a background (2) modulating the contrast of at least one element (3) receiving feedback from the subject via at least one input device (4) quantitatively refining the received feedback relative to the scene (5) adjusting the contrast relative to accuracy of the quantitatively refined feedback (6) calculating a critical threshold parameter for the subject and (7) recording a critical threshold parameter onto a tangible computer readable medium. 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.
