For a long time, I hared about the stereoscopic image\video, but I did not test them. I though that the 3D art is not useful for who, watch the life by using of one eye. Online, some friend told me that the problem occurs with only some types of stereoscopy (I am not sure if one eye is enough or not). I like to know your opinion because there are many specialists here. If one eye is enough, I will buy tools of 3D for the computer to watch new things.

Hello.
I'm not a doctor but I'd say stereovision with one eye is impossible. It's like your stereo. It's impossible to hear stereosound with only one speaker.

Sorry, two eyes are definately required to sense depth in an image.

That's where the name comes from ;)

You most definitely need to eyes, that's the whole point in stereoscopy

Sorry bud :(

However, even though you need two eyes to see true stereoscopic images, you might get some pleasure from Lenticular images which can include "Motion" in the image. That is, you turn the picture one way and you see the beginning of the sequence. As you turn the image the other way the image seems to move or do something. It wouldn't look 3D to a person with one eye but still might be kind of cool.

Just search the internet for the word "Lenticular".

Also, here is a freaky thought:

There was an experiment that used glasses to make everything look upside down. People where told to wear the glasses for weeks on end. After a few weeks the people in the experiment starting seeing everything rightside up, the way it should be...but while still wearing the glasses! When they took the glasses off everything looked upside down! LOL. Of course, after a few weeks without the glasses everything returned to normal for them. The brain simply adapted to the aberation.

So, what if you took a stereo image splitter lens like for a camera, and mounted it onto a frame that someone with one eye could wear like glasses. Now the person with one eye is seeing a split image through that one good eye. Would the brain catch-on and adapt like in the above experiment? Would it process the image in true stereo after a while? Or would it just confuse the brain and give you headaches?
Remember, the brain and optic nerves are nothing more than conduits to get the information to the Occipital lobe of the brain. That is our video processing unit. The experiment has "Face Validity" at least.

P.S. I think if it worked the person with one eye would end up with half the resolution of a person with one regular eye.

Wow! That's an awesome SamualT. IT might limit the person's field of view, but if it let them see depth...

One other thing, and a correction:

Should read:
"Remember, the EYES and optic nerves are nothing more than conduits to get the information to the Occipital lobe of the brain."

And:
I'm not sure it would work if the person hadn't grown up seeing in stereo. The Occipital lobe must have had previous experience with stereo before. The brain is very elastic. If a brain area isn't used for its original purpose then it will be used for something else. If you were born with one eye you could probably never see in stereo correctly.
Its the reason why if you don't learn a language by a certain age then you can never learn to be fluent in any langauge. Like the little girl who was abused and kept from learning anything till age 13 or something. She had never been taught to speak in any way. She could learn basic noun-verb stuff but never got over 2-3 word sentences. It was too late for her to learn a language.
But it probably would work for someone who had lost an eye. But like you said, it would cut their field of view. And you would have to wear silly headgear. Probably not a tradeoff most one eyed people would be willing to make.

To get even more bizarre:
You could probably rig up all kinds of lenses and mirrors to do really strange things like give yourself eyes in the back of your head, extra pair of eyes sitting above your head, etc...And the brain might even adapt to it. Doubtful, but possible. I can't think of a single reason why anyone would want to do that but it would make some very interesting experiments to read about.

P.S. Do you see what graduate work will do to your thinking! LOL.
