Do not think that the third eye is similar to slip, as a third ear in the mouth agitated Ivan Ignatyevich of the “Captain's daughter”: “you in the snout, and you have it in your ear, the other in the third - and move on”. We actually go about to see three eyes.
To see three eyes? Probably wouldn't buy third eye?
Imagine, we are going to talk about this vision. Science is unable to give the man a third eye, but in its power to give the ability to see an object as it would appear creature with three eyes.
Let's start with the fact that the person who lost one eye, it is possible to consider stereoscopic pictures and get them the impression of relief, which is to perceive directly he can't. For this you need to design on screen, quickly replacing one another, the images intended for the right and left eyes; that people with two eyes sees at the same time, the one-eyed will see here sequentially, in rapid succession. But the result will polechitsya the same, because it is very rapidly changing visual experience as well merge into one as simultaneous [May notice that sometimes surprising relief cinematic paintings explained, in addition to the previously mentioned reasons, even partly the effect of which now reads: if the machine that produced the shooting, rhythmically rocked (as is often due to the operation of the mechanism behind the tape), then the images could not identical; quick change these images on the screen they merge into plow consciousness in the relief image.].
But if so, then the man with two eyes can see: one eye or two with a rapid series of pictures, and the other is another photo taken from another point of view.
In other words, with one subject takes three photos that meet three different points, like the three eyes. Then two of these images force, rapidly alternating, to act on one eye of the observer; in rapid alternation impressions merge into one complex relief image. This image is attached another third impression from the other eye, which looks at the third shot.
Under such conditions, though we see only two eyes, but the impression we get quite the same as if you were watching three eyes. The relief when it reaches the highest degree.
