3D Glasses - How Do They Work?

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.

If you have used a  View-Master viewer, it's easy to see how your binocular vision system works.
 

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!

The binocular system of vision depends on the fact that our pair of eyes are located approximately two inches distance between. (1.9685039 in.) Separated. The binocular vision system works since the brain is able to utilize the different perspective obtained from each eye and process them together to calculate distance. Even though pictures your eyes perceive are slightly different the brain will connect the images it sees. The correlation may distinguish items in the pair of scenes it views and determine the distance between the item in the pair of images. Objects that are farther apart in the two images are closer than objects that are not so far separately.

View-Master and stereoscopic viewers are examples of binocular vision systems. In a View-Master, each eye is presented with an image, and the images are created by two cameras that photograph the same image from slightly different positions. Each of your eyes sees only one image so you are able to correlate these images automatically.
