In a reachâgrasp task for targets within the binocular visual field, subjects switched between left and right eye dominance depending on horizontal gaze angle. On average, ocular dominance switched at gaze angles of only 15.5Â° off center.
The ideal optimum viewing distance is affected by the horizontal angle viewed by the camera capturing the image. One concept of an ideal optimal viewing distance places the viewer at a point where the horizontal angle subtended by the screen is the same as the horizontal angle captured by the camera.
