FREE VIEWING STEREO IMAGES
(without the use of glasses )
Experience an increase in Alpha brainwaves when free viewing! parallel (=) stereo images cross-eyed (x) stereo images
Notice the moment of slipping into the experience of three dimensional space. The brain seems to have locked onto the super-imposition of the two images, and at that very moment a brain-wave shift can be noticed. Alpha brain waves have increased. This can be experienced as a feeling of letting go, a sigh, a deepening relaxation. Apparently, visually harmonizing the two halves of the brain in this unusual way promotes an increase in alpha waves. Brain wave measurements were taken with an analyzer from IBVA Technologies, Inc.
There are two ways to free view the images in stereo, parallel (=) and cross-eyed (x). Parallel viewing means that the left eye's image is on the left side and the right eye's is on the right, so it involves letting your eyes stray until they are parallel. Cross-eyed viewing involves crossing your eyes so that your right eye sees the left image and vice versa. I provide examples of both of these on separate pages.
Parallel stereo asks your eyes to focus nearby while orienting themselves to look as far away as infinity. You can practice with placing a piece of paper between your nose and the screen, or halfway if you're further back. Make sure each eye only sees one image. It takes practice, so be patient. Eventually it can become second-nature.
This involves orienting your eyes so they are looking at a nearby object while focusing further away - the opposite of the above description. You can practice by holding up a finger between your eyes and the screen, and focus on the finger while paying attention to the stereo images. By moving your finger closer or further from your eyes while focusing on it, the images will converge or diverge. Move your finger until the images overlap - until it seems there are three images on the screen. The middle one will be the stereo image. With a little practice, you should be able to cross your eyes and get the stereo image without using your finger for assistance.
