| Schemes (figures 1 and 2) of double images merge in conditions of physiological doubling. BECAUSE of identical images merge in the tests A and B, a perception of "an imaginary object" emerges. It consists of three virtual images. This perceived picture looks like the following: in the center ab - the image is perceived as a binocular image, a - the image is perceived as a monocular image by the right eye, b - the LEFT EYE PERCEIVES THE IMAGE AS A MONOCULAR IMAGE. |
| And, (figure 1) if the area of binocular fixation is located behind the plane of double images, the binocular image - ab is perceived in the space behind the plane of the real double image at the distance L from the patient. This phenomenon is referred to as "depth effect ". All the elements of the "imaginary object” is perceived larger than real in this case. |

If the area of binocular fixation is located behind the plane of double images (figure 2), the binocular image - ab is perceived in the space behind the plane of the real double image.
The elements of the "imaginary object" are perceived as smaller than real.

| In such state the visual system is flexible, its’ managing mechanisms can be reorganized and controlled. |
