CROSS-EYED FOCUS INSTRUCTIONS

Use an absolutely steady gaze and aim the right eye to the left side of the object placed in front of you and the left eye to the object's right. Both eye's visual axis will cross between you and the object. Do not look at the object with your eyes because that will create a converged focus. Place only your awareness on the external object. PRACTICE, PRACTICE, PRACTICE.

CROSS-EYED FOCUS EXPERIMENTS

  • Create a cross-eyed focus on a single external candle or object with only your awareness on the object. Observe the sight sensation of two images.

  • Close one eye then the other to see which image disappears.

  • Observe cross-eyed vision's double image size and distances.

  • Become aware of the differences between the parallel and cross-eyed focus double images.

  • Place two identical objects approximately six inches in front of you six inches apart. Focus your right eye on the left object and your left eye on the right object. Be aware how the two external objects disappear and become one positive afterimage closer and inbetween the two objects at the intersection where the visual axises cross.

  • Using two identical objects, be aware of the parallel focus differences which produce four images and the cross-eyed focus which produces a single image.

  • Experiment with varying the eye's cross-eyed position with awareness on the object to produce double and triple vision, as well as keeping the eyes stationary but changing the object's distance.

  • Observe which images are transparent and which appear solid.

  • Experiment using cross-eyed focus on two identical candles but one is white and the other is red placed six inches in front of you six inches apart.

  • Experiment with a simple form of eidetic imagery using a cross-eyed focus.

CROSS-EYED FOCUS PROCESS

A cross-eyed focus on an external object places the visual signals in the LE-LVF (green) and RE-RVF (red) at NONcorresponding points along the visual pathway.

The LE-LVF (green) signals refract at the cornea and lens to the left eye right retina side, cross the optic chiasm over into the right hemisphere. The LE-LVF signals follow the right optic path to the cerebral cortex, cross the corpus callosum into the left hemisphere, follow the left optic path to the optic chiasm, cross over to the right optic nerve, reach the right eye left retina side and exits into the RE-RVF area. The sensation of a left side, smaller, further back, transparent image is observed.

The RE-RVF (red) signals refract at the cornea and lens to the right eye left retina side, cross the optic chiasm into the left hemisphere. The RE-RVF signals follow the left optic path to the cerebral cortex, cross the corpus callosum into the right hemisphere, follow the right optic path to the optic chiasm, cross over to the left eye right retina side, reverse refracts and exits into the LE-LVF area. The sensation of a right side, larger, closer, transparent image is observed.

A cross-eye focus on two identical pictures/objects put the visual signals at the visual axis of each eye. The visual axis crossing creates the interference pattern resulting in the sensation of sight of a single, closer, smaller and solid positive afterimage. A cross-eyed focus on two identical candles but one is white and the other is red also produces a single, closer, smaller, solid positive afterimage at the visual axis crossing. But the single candle is not a blend of white and red to pink. The single candle image switches back and forth from white to red.

A cross-eyed focus on two groups of random letters will overlap the noncorresponding visual signals into a single readable eidetic image.

MISSING LINK CLUES

  • Supporting evidence that the visual fields remain separated.

  • Additional proof that both eye's RVF are smaller and more distant and the LVF are closer and larger appear.

  • More signs that image transparency is due to a single noncorresponding visual field layer versus the multilayered visual fields in a converged focus surface.

  • When each eye processes identical visual field signals in a cross-eyed focus, the results are an interference pattern at the visual axis crossing creating the sensation of sight of a smaller closer single solid image.

  • The candles white/red color switching continues to suggest the left and right eye visual signals never become one but remain separate although overlap each others visual angles. The color changes are created by the left and right hemisphere switching control.

  • Cross-eyed focus creating eidetic imagery continues to show the visual field layered effect.

CROSS-EYED FOCUS QUESTIONS & ANSWERS

Is a cross-eyed focus difficult to achieve?
The eye's natural habit is to move in synch with each other resultig in a converged focus. Cross-eyed focus is unnatural and more difficult to achinve due to life-long habits.

How does a cross-eyed focus create double images?
A cross-eyed focus creates double images by placing each eye's visual signals at non-corresponding points along the visual pathways.

What are the differences between converged, parallel and cross-eyed focus images?
The same chain of events occur in all types of vision. But visual variations occur due to the different visual axis focus points which places the visual signals in different visual fields at corresponding or non corresponding points. Image size and distance are changed according to which visual field the signals are in. For example:

  • A converged focus places both eye's visual signals at corresponding locations along all visual pathways with depth perception and solidity.

  • A parallel focus places the left image closer and larger and the right image is smaller and in the background. Both images are without depth perception because the signals are on a single plane at non corresponding points without the opposite angled layered effect.

  • A cross-eyed focus reverses the closer and larger image to the right side and the smaller background image is on the left side. Both images also have no depth perception being on a single plane.

Does the size and distance of double images suggest a layered visual system?
Yes! A six-layered visual system becomes apparent.

How does a cross-eyed focus on two identical external objects create a single image closer and inbetween the two external objects?
A cross-eyed focus on two identical objects create a single, closer positive afterimage because the crossing of the visual axises where the two incoming positive visual signals meet with the two outgoing negative visual signals and act as the original backdrop creating the interference pattern needed for the sensation of sight. The image is closer due to the visual axis location, and smaller due to the ratio of the image and visual axis crossing point.

What creates the sensation of sight - a positive external object backdrop merging with outgoing negative visual energy or the interaction of positive and negative energy at the visual axis crossings?
My speculation is that nature's duality allows the sensation of sight to occur either using a backdrop or the crossing of the visual axis.

Why would the crossing of the two negative visual axis energy create a positive afterimage and not a negative afterimage?
The visual axis crossing produces a positive afterimage because the two paths of negative visual energy exiting the eyes are also colliding with the incoming positive energy from the external object.

How does Man see stars instantly?
Visual axises crossing could explain why the exiting negative energy does not have to reach the stars in order for the sensation of a star to be observed. Star images may materialize at the point in space where the visual axises meet or when negative energy interacts with a backdrop, perhaps the earth's atmospheric layer or an individuals energy field cocoon.

How do babies know to converge their focus?
Babies learned to converge their focus naturally by focus of their attention towards the sound or object which results in the converged focus.

What chaos would be created if individuals were to use a cross-eyed focus dominently?
An individual with a dominent cross-eyed focus, for example, would have two identical cars approach side by side but would observe a single car closer inbetween the two real cars. The observer would move to either side to avoid the single car. SPLAT ! He would be struck by one of the real cars he did not see.

What is observed when using a cross-eyed focus on one red and one white candle placed six inches apart six inches in front of you?
A cross-eyed focus on one red and one white candle will produce one single, closer candle image with the red and white colors switching ghostly back and forth. The switching is caused by the on and off right and left hemisphere switching of the left and right visual field impulse signals.

What clue is presented by the red and white colors switching back and forth?
The clue presented by the color switching clearly shows that the left and right visual field pathways always remain separated never merging the signals, otherwise there would be one pink candle. It now becomes apparent that the visual field signals from each hemisphere are alternately layered visual impulses during the sight sensation.

How does eidetic imagery work?
Eidetic imagery patterns when viewed singly reveals no recognizable pattern but when simultaneously presented to each eye using a cross-eyed focus, an identifiable message emerges by combining the images. Eidetic images are most frequently experienced by school age children and diminishes in adolescence as the habit of a converged focus strongly dominates.
