There are relatively few studies on distance judgment cited in the psychological literature. Allgaier (1) developed a test of depth perception involving movable pegs. He found that color and size of the pegs had little effect on judgments. However, induced visual defects and astigmatism materially decrease the ability to judge distance. Visual acuity seems to be the only factor reported which is significantly correlated with distance judgment.
