I heard about these on Dvice and just HAD to go check it out! I was laughing so hard, but it would seem that they are, at some degree, a real product! Honest! If you are totally annoyed by 3d in the movie house and there is no 2d alternative, then these would it seem be just the thing. As you know 3d works by showing 2 slightly different pictures on the screen. To get the 3d effect each lens in the 3d glasses lets just one of those images per-side through, while the other lens lets the other image through and blocks the image the other side passed. How the 2d converters work is both lens block the same image, letting only one frame of the effect through. Thus eliminating the effect.
As you can see in the image, they do appear to have polarized elements, so..lol it might just work.
But for me and maybe for you, if you are totally annoyed by the 3d hype - I have gone one step further and blocked not only one side of the 3d but both going for total conversion.
Here is the 3D to 2D site so you can make up your mind. As the folks at Dvice said They totally called this during April Fool.....loma
