Stereoacuity of Black-White and Red-Green Patterns in Individuals with and without Color Deficiency

Figure 2

Test pages used. A pair with a red and green pattern seen by the (a) left eye and (b) right eye. From top to bottom, the disparity of the stereo targets is 80″, 70″, 60″, and 50″, respectively. From top to end, the stereo symbol in contour-based graphs is left, right, down, and up, respectively, while the stereo symbol in random-dot graphs is down, up, right, and left, respectively. (c) The simulation of the percepts generated by the test images (a, b). This is an attempt to simulate what a subject might perceive when fusing (a) and (b) as one image. The stereo symbols appear to pop out of the background plane.
