|How Do You Create 3D Viewing
with 3D Glasses?
A truly astounding binocular vision system based around having two eyes is present in most human beings. Objects in the range of 20 feet (from 6M to 7M) away, the binocular vision system lets us easily tell with good accuracy how far away an object is. 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. Distance can still be perceived with one eye, however the accuracy of the measurement of that distance decreases. As such you will have to compensate by depending on visual cues or focusing on distances which are slower.
To observe what differentiation the binocular vision system creates,
have a friend toss you a ball and aim to grab hold of it keeping your
eye closed. Also try it in a fairly dark room or at night, where the
difference is even more noticeable. Don't forget, it is much easier to
catch a ball with both eyes open!
