Relationship between monocular and binocular depth acuity.
Estimates of monocular and binocular depth acuity were obtained on two samples of subjects with adequate visual acuity and capacity for stereopsis. Both a method of average error and a modified method of limits were employed to secure the estimates. Eight ratios of binocular to monocular depth acuity ranged from 2.4:1 to 4.2:1 at a distance of 15 ft. The results contradict the familiar generalization that binocular depth perception is about 20 times as acute as monocular depth perception.
