Most human beings come equipped with two eyes and an absolutely amazing binocular vision system. If the objects are not more than 20 feet away (approximately 8 yards) It is the ability to see with two eyes that enables us to measure with precision the distance to an item. To illustrate, we have the capacity to immediately determine the relative and absolute distances of any number of object that may fall within our field of vision. Looking at the world with one eye closed will still allow you to perceive distance; however, your accuracy will decrease because you must rely on visual cues for focusing distances.
Have a friend throw a ball to you while you have only one eye open, and you will see how much the binocular vision system affects your perception. The differences become more obvious when tried in a darkened room or at night. It is much harder to catch a ball with one eye open than with two eyes open.

Binoculars are designed to fit the general frame of the human face, having an average of two inches span between the lenses. (5 cm) Separated. So, the perspective of each eye is a little bit different and your brain’s binocular vision system calculates distance by using this difference. The brain possesses the capability to connect the images seen through the two eyes even if they are somewhat unlike. The correlator can pick out objects in the two scenes it sees and calculate how far apart an object is between the two images. Objects that are farther apart in the two images are closer than objects that are not so far Separated.
If you have ever used a View-Master or a stereoscopic viewer, you have seen your binocular vision system in action. The View-Master presents a slightly different picture to each eye; the pictures are taken at slightly different angles by two separate cameras. Since each eye sees only one image, your eyes know how to automatically connect these images together.
