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.
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.
