So there is an effect where if you close one eye while watching a 2D movie, it appears slightly more 3D. This being because your depth perception no longer has the cue from two eyes.

(As an additional effect, the people in the movie appear to be a bit slimmer due to not being compressed into 2D).

The downside is you no have a lesser angle of vision.

So I had an idea, why not with some mirrored glasses or a prism of some kind, direct both eyes so that the light enters a point in between your eyes and gets split and directed into both eyes. You would lose some depth perception, but your brain would imagine the 3D-ness. Thereby you might be able to watch a 2D movie and it would appear 3D. But I wonder would you still get the same periferal vision?

The idea is that it would mimic one central eye like a cyclops. And you would view a movie in the same way a cyclops would.

You might still get a little eye strain because your lenses in your eyes would be trying to focus wrongly but that might not be such a problem if the movie is quite far away.

Would this invention work or has it been invented before? (I imagine there might be some appendage to a telescope that splits the single lens into a binocular eye piece.)
