Vision correction by stereoscopic 3D vision correction using image pre-compensation for each eye wit
I have been toying with this thought for some months now and have discovered only a little bit of information on a subject that I would expect to have been covered by at least several people/groups in the world by now.

So, I wear glasses. It sucks, I would do nearly anything to have perfect eyes!!!!
And, I own a computer. Who doesn't?
And, it is equipped with stereoscopic 3D glasses and monitors. Who doesn't? Oh, wait....

My thought is this. Why can't my computer display the image in a distorted manner as to match the astigmatism that hinders me from perfect sight. This could be accomplished simply by taking my eye glasses prescription and essentially doing the reverse of what my glasses do. The result would be that my eyes would take an image that has been distorted and focus it on my retina rather than taking a perfect image, distorting it with my glasses, then focusing that image on the retina. This idea could be further enhanced using the stereoscopic 3D glasses in such a manner as to provide a "pre-compensated" image to each eye as per that eyes prescription needs. Like I said, I have toyed with this idea for some time. I don't have the graphics programming knowledge it would take to do such a thing and I have stated that I would expect somebody already has conceived this idea.

My expectations it seems are correct, see I expected [url="http://www.ncbi.nlm.nih.gov/pubmed/22255429"]this[/url], [url="http://dl.acm.org/citation.cfm?id=1090834"]this[/url] and [url="http://www.patentgenius.com/patent/6018339.html"]this patent[/url].

The reason I am posting this is as follows:
Firstly, I am wondering if anybody at nVidia has considered such a thing since a video card company would be poised in the right position to implement such a technology.
Secondly, I am wondering if anybody else has any further information about this topic. I have spent some time and have only come up with the above links.

i think that is not possible, glasses work like a prism, they redirect the light changing your "focal point" and since the 3D glasses are just flashing LCDS, i don't think that is possible only by changing the image properties, you see, if you have myopia, and you lost the focus on distant objects you would not be able to see the monitor pixels with quality, and the image would be blurred the same way the oposite would also happens, since your eyes focal point if far away and if you got the monitor to close that focal point would not be possible without changing the light convergence.
the only solution to use 3D glasses without prescription glasses would be a 3D glass that have curved lens (minus os plus depending on your eye problem) than it would be possible, but it would work only for you and people with same problem and same lens distortion what is simply not viable.

Just buy a pair of lenses that match exactly with your 3D glasses, that is the cheapest solution so you could "fit it" inside the 3D glass...

I think there is a misunderstanding on what I was talking about.
The glasses themselves would only be aiding in this idea allowing for each eye to have a unique image project. The real work would be on the PC where the graphics would be distorted on purpose in a process that is called "pre-compensation". I have previously seen images that I was able to see clearing without the glasses, but not with the glasses, so I do know this is possible. At least for me as I have an astigmatism. My eyes without glasses have no issue other than it being blurred and compressed horizontally while vertically they have no issue. So, if the PC stretched the image (and a few other distortions to match my prescription lenses), I would be able to see better.
Essentially what my glasses lenses are doing is purposely bending the image so that when it enters and exits the lenses in my eyeball, the distortions cancel out. In theory this would mean that the image leaving the eye's lens should be perfect.

As far as "cheapest" solution. My 3D monitor cost me less than a pair of glasses...

You are right that glasses work sort of like a prism. This is not only what makes them possible, but it also causes problems with some people because by their very nature, prisms bend each color in the light spectrum slightly differently. This causes colors on the far ends of the spectrum to shift based upon how you look through some glasses and greatly reduces clarity of a projected image. Also, I am quite aware of the technology behind the 3D vision system.

Well I understood the idea, but like I have said I don't really think that this pre-compensation is something possible, maybe for a very specific situation, but this pre-compensation doesn't looks like something "achievable", since the main problem is the distance the monitor is to your face and not the content that is being show.
Showing one image for each eye is not the main problem, if you close one of your eyes and look at the monitor it still blurred and only a light convergence can fix that, converging the image probably won’t fix that problem, but yes, if they really find a way to do that, a 3D glasses would help to show a different image to each eye with its own properties.
I really don't know much about this but it looks like it still only on paper.

Well yes, I agree. Distance from the monitor to the head is a problem. There has been a handful of 3D technologies that require this to work without glasses. If this distance is kept relatively constant or can be adjusted through the use of a webcam it would work. Also, this would depend upon each users unique eyeball. Once achieved, it is conceivable to allow for very slow adjustment of the image in the direction of normal. This would slowly train the eye in the direction it needs to go to work normally. Obviously not every eyeball is capable of relearning like this, so this would not work for everybody.
