The two binocular depth cues are retinal(binocular) disparity and convergence. They help us judge reality by giving us a perception of how far away an object is.
Retinal disparity
It is a binocular cue.

Neural convergence refers to the phenomenon of multiple sensory receptors giving information to a smaller number of neural cells. For example, in the retinal periphery, many photoreceptors converge on a smaller number of ganglion cells so that the brain doesn't have to process inputs from each photoreceptor.
The plural of disparity is disparities.
Disparity in a geographical region.
Retinal veins are larger than retinal arteries. Retinal veins are between 2/3 to 3/4 times larger than the arteries of the retina. Retinal vein are also darker red then the arteries.
Convergence of telecommunications
retinal breaks or detachments; retinal ischemia (retinal tissue that lacks oxygen); neovascularization (proliferation of blood vessels in the retina); Coats' disease
Retinal vein occlusion refers to the closure of the central retinal vein that drains the retina or to that of one of its branches.
Convergence is a noun.
