binocular vision

The visual perception of a fused single image from 2 eyes viewing the same object from slightly different vantages. Binocular vision results from the convergence of neural signals from the corresponding points on the 2 retinas on the same binocular cell in the primary visual cortex. If the images received from each eye differ widely in shape, orientation or luminant contrast, the images then rival each other rather than fuse.

This condition was identical to the stereoptic condition, with the exception of the virtual objects being offered such that both eyes were presented with the exact same visual perspective.
In addition, Shakespeare augmented the stereoptic illusion by allowing the interplay of realistic, allegorical, and supernatural elements within the same character: Iago is simultaneously an ambitious soldier rebuffed in his quest fo position, a machiavel, and even ("I bleed, sir, but not killed" [5.2.289]) an embodiment of demonic forces.
