In addition, the resolution of the two disparate images, though highly similar, must be simultaneous, subconscious, and complete.
(After-images and "phantom" images are symptoms of incomplete visual resolution, even though the eyes themselves exhibit remarkable acuity.)
Recent advances in computational machine learning now allow monocular depth for an entire scene to be algorithmically estimated from a single digital image by implicitly using one or more of these cues.
[6][7] Vision has been known to play an important role in balance and postural control in humans, along with proprioception and vestibular function.
[8][9] Studies comparing monocular vision to binocular (two eyes) vision in cataract patients (pre and post surgery),[10] glaucoma patients (compared with healthy age matched controls),[11] and in healthy adults and children (in both binocular and monocular conditions)[8] have all shown to negatively impact balance and postural control than when both eyes are available.
