Explanation:

The term stereoscopic vision refers to the human ability to view with both eyes in similar, but slightly different ways. This allows humans to judge distance, which develops their ability to have true depth perception. For people and animals that have stereoscopic vision, each eye sees a similar, but slightly different image. Stereoscopic vision also helps humans to handle and manipulate small objects with their hands.Stereoscopic vision is not the only way that humans judge distance. The human brain also uses the focal distance to an object to estimate distance. The distance is judged based on how the eye must be focused in order to clearly see an object.
