Question

Which of the following statements best explains the relationship between eyes and depth perception?

A.) Having two eyes is not important; our brains need information from only one eye (left or right) to form a perception of depth.

B.) Each eye sees objects slightly differently because each eye is in a different location. The images are combined in the brain to form our perception of depth.

C.) Having two eyes is not important; depth perception comes from our left eye only.

D.) One eye sees objects at a close distance, and the other eye sees objects located far away. The images are combined in the brain to form our perception of depth.

Answer 1

The correct answer is B. Both of eyes see the images a little differently, because of the horizontal separation of the two eyes. This difference is proportional to the relative depth. Brain measures these differences and we obtain a stereo image of the objects that we see.
