What Is Stereopsis?

Question:
What is stereopsis?
Answer:
Roughly, you can think of stereopsis as depth perception. When someone with normal functioning vision looks at an object, each eye views it from a slightly different angle, and sends those pictures back to the brain. The brain processes these differences and integrates them into the one image we see. These subtle differences help us judge distance between ourselves and an object (what is nearer, etc.) and endows us with 3D (three-dimensional) vision.
