So technology companies are racing to develop the best 3D glasses free solution. Too bad for them Mother Nature beat them to it. Humans have the ability to view 3D imagery with no glasses at all. Free-viewing stereoscopy is the term used for this special way to see 3D.How to do it:
When looking at a stereo pair, you should look 'through' the picture, so that your left eye looks at the left picture, and your right eye looks at the right picture. When you relax your eyes, you should notice similar objects in each of the pictures moving toward each other until they overlap each other. When the pictures overlap completely, you should be aware of three pictures side by side. When your eyes get used to looking at the 'middle' one, you should see it in stereo (3D). Tip:
If it proves too difficult, it may help to put a piece of cartboard vertically between the pictures and looking with the cartboard between your eyes.
