3D or stereoscopic movies are all the rage now and people are trying to create ways to show stereoscopic movies without having to wear those darn glasses.
HERES MY MYTH: Late at night I was wearing some old 50s style red & blue anaglyph 3D glasses while working on a 3D movie on my computer. All the lights were off except for my computer monitor. I had been wearing the glasses for about 2 hours and I got up to get a glass of water and when I removed them I realized when I shut my right eye everything was red and when I shut my left eye everything was blue. So here is the myth when I looked at my computer monitor displaying the 3D video I could see the stereoscopic illusion WITHOUT GLASSES!!!!

Ok, but where is the myth? I don't think people would want to spend an hour wearing 3D glasses just to enjoy a couple minutes of the same thing but without the glasses. Besides, while your eyes are adjusting back to normal after you remove the glasses, the depths will be all screwed up since the wrong eye is seeing each image.

The after-image produced by pigment saturation only lasts a few seconds, at best. And you have to saturate for at least several minutes just to get there.
There are several other gaping holes in this story.
Just the most obvious problems: the colors are reversed from what was intended when the image was produced; this often works OK, but causes significant eyestrain. And the colors are complements of the colors in the original filters; complements don't correspond to the red and blue required by the technique, which again lessens the effect and produces eyestrain.
Worst of all: no one uses red and blue 3D imaging anymore, except as a novelty. People want color, and you can't get there with this approach. You need polarizing filters. And these don't produce any complementary polarization in the eye, making any adaptation of the technique completely useless.

Here's an idea. I wear Polarized sunglasses. Just set those to work with 3D movies and I thimk people should be all set.

Regular polarized sunglasses wouldn't work. Each eye has to be polarized a different way so that each eye only sees one of two images.

so you polarize each lens that different way. How hard can that be?
