Population distribution of stereoscopic ability.
Of 188 unselected biology students participating in one or both of two tests measuring stereoscopic depth detection ability, 183 (97.3%) were able to see a depth difference at horizontal disparities of 2.3 min arc or smaller. At least 80% could detect depth differences at 30 sec arc disparity. These findings indicate that most people are able to take advantage of the increasing utilization of stereoscopic displays.
