Then why don't you? It's cool. Eg. 3D games look really cool that way.
If nothing else, watch someone else playing eg on youtube or whatever.

I don't understand. The general public doesn't have access to games or
movies? I don't get it.

Ok, maybe we are having a confusion of terminology.
This is a 2D game:

This is a 3D game:

Clearer now?

I think he means the public don't have access to stereoscopic viewing
technologies.
The military has (for example) those TV screens with the weird
flickering LCD glasses that give you a headache but also generate a true
full-colour stereo image...

Then it's unrelated to what I wrote, and an odd response.
I was nowhere talking about any stereoscopic viewing technologies.

Not in 3D. Just in perspective.
Contrast with a movie theatre where you wear special glasses, or with a play
or puppet show.
My point being that even with both eyes open, looking at light projected on
a 2D flat movie screen, you still have a sense of depth. You know Bruce
Willis' car is closer than the bad guy's helicopter even if it's a flat
photo on a flat screen.

That's a game drawn in perspective, is my point.
This is a 3D movie:

I was agreeing with you. Not only can you see "depth" with one eye closed,
you can see "depth" that isn't there with both eyes open. You don't have
that hard a time judging how far away the enemy is and who is closer in a
1st-person shooter, regardless of how many eyes you open.

Sorry, I don't get your point.
*My* point was that if you start watching a 3D game (perspective, whatever
you want to call it) like Doom or Half-Life with one eye only, you will
start getting quite cool depth perception. Not many people know this because
they have never tried.
*Your* point I missed completely.
Rather than nitpicking about terminology, just try it. It's cool.

Of course the brain needs the visual clues given by parallax and other
even subtler details (such as recognizable shapes) in order to maintain
the compensated depth perception. If you eg. pause the game/video for some
time, you will start losing the depth perception again, until you resume
it and start getting the visual clues again.
With stereo vision you maintain the depth perception even with a
completely static three-dimensional scenery.
