Screening for Stereopsis of Children Using an Autostereoscopic Smartphone

Figure 6

Legend of random dot stereo acuity test part 3. (a) The picture viewed by the left eye. (b) The picture viewed by the right eye. (c) Simulation of the percepts generated by the test images. At a correct watching condition, the right eye would see letter “R” and could not see letter “L”; meanwhile, the left eye could only see letter “L” without seeing letter “R”. In line A, “circle” would appear out of the plane (16 px, equivalent to 400″). In line B, “apple” would appear out of the plane (8 px, equivalent to 200″). In line C, “square” would appear out of the plane (4 px, equivalent to 100″).
