• What Is Stereopsis?


    Question:

    What is stereopsis?


    Answer:

    Roughly, you can think of stereopsis as depth perception. When a visually normal human being looks at an object, each eye sees it from a slightly different angle, and sends those pictures back to the brain. The differences between the two images are integrated into a single one, and the differences are used to show what is nearer, etc., creating the 3D effect.
