Some depth information can only be obtained when both eyes are viewing the world these types of information are termed binocular cues to depth. In contrast, monocular cues can be obtained using only one eye: binocular cues (convergence): Because the two eyes converge on an object when we are viewing it, the brain can use the angle of convergence as a cue to how far away that object is. For example: the larger the angel, the nearer the object, vice versa. Whenever we are not focusing on an object, the image of that object falls on different points of the two retinas. Amount of disparity (difference) between the two retinal images can be used as a cue for distance. Try holding up two fingers one in front of the other.
