Universal Swing and Variable Swing

I have noticed that during my flashes of improved vision the space appears transparent and three-dimensional. The entire view field seems overwhelmingly deep and swings slowly in whole, objects at different distances swinging with different speeds.

Looking to reproduce this feeling after few attempts I have found, guess what, that it is the same thing that is described by Dr. Bates as "universal swing" and "variable swing". It feels like realizing that the space is not flat and objects are located in different planes. Even if you can't see the detail, you can always see that objects change their relative positions to each other as you move your body, head or eyes. The easiest it is to notice when doing the long swing. Then, you can make the movement shorter and still notice that the perspective on objects slightly changes. You can also remember this feeling with the eyes closed.

An important point is that you do not pay attention to the blur and not try to clear it away, but instead only pay attention to the swing.

When successful, the strain decreases so that I become able to stop physically moving my head and then keep the swing purely imaginary. It is slow and short, as it should be.

If I am aware of the universal swing for long enough - a couple of minutes, my eyesight improves automatically. So I now remember to practice it all the time. It is easy when you walk outdoors. The challenge is however to practice it while working at the computer screen or book, where the view field is mostly flat.
