Question to entrepreneurs

Humans, like primates, have evolved over the course of evolution an incredible visual system that makes it possible to see the world in three dimensions and estimate distance with a great degree of accuracy.

Our eyes are positioned a short distance from each other on the front of the face, while in many animals the organs of vision are located on either side of the head.

Despite this, our eyes also see the same image slightly differently (monocular vision), but due to the special properties of our brain to unify the image, they give the perception of depth and volume of objects.

This creation of a single image is called binocular vision.


The development of some organs in humans, due to their complex structure and functions, does not end immediately after birth. Binocular vision requires a certain development of higher nervous activity, so the final formation of this function is expected before the age of 15, in addition, the optical system must have the following characteristics:

  • a visual acuity of at least 0.4 diopters, ensuring a clear image on the retina;
  • normal tone and full range of movement of the oculomotor muscles, which allow parallel installation visual axes.

Due to this position, the rays are projected into the central depression of the retina;

  • equal refraction of both eyes. With a difference of 4-5%, binocular vision becomes impossible;
  • normal accommodation, convergence and divergence for displacement of the optical axes;
  • full retinal development;
  • complete symmetry the location of the eyes. If any of them is displaced due to trauma, tumor, hematoma, inflammatory infiltrate, then the alignment of the fields vision becomes difficult and stereoscopic vision is impaired.


Binocular vision was formed in humans during evolution under the influence of the environment. For his survival, it was much more important to see what is happening behind the foliage and bushes than what is happening behind.

Part of the view is closed for one eye, part for the other, but when the images are combined, a "miracle" occurs and we actually see "through" the obstacle.
