Overview
Beyond the visible turn, the assessment checks binocular vision: whether the brain fuses the two images, whether depth perception (3D vision) is present, and whether a deviation is controlled or decompensating.
Measurements are taken in different gaze directions and distances, because many deviations vary with where and how the person is looking.
