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 f- number of the human eye is about 2.55, whereas for a standard Camera it is 1.8, and the most sensitive vision is of the deep sea Crustacean Gigantocypris (f-0.25). The position of eye over the head decides the field of vision. There are two types of fields of vision viz., the field of view of an individual eye, and overlapped portion of field of view (binocular field). When the eyes are on either side of the head, view is almost panoramic, but there is a loss of stereoscopic depth perception.
