Hi

I'm pretty sure that your field of view with one eye closed it a lot more then 30 degrees.

I'd say it's more then 90.

I can stare with my left eye at the center of my monitor and can see the lamp on the left side of the room that is actually slightly behind me.

Of course it doesn't look clear like what I'm staring at but it is visible, it's what you can't do on screen but it is what makes you feel in the environment and not just like you are looking at it.

Gamers are trying to get this, in the world effect buy using multiple monitors that display the peripheral vision on monitors set at a 45 degree angle to the center one.

I'd do that if I could afford to by 2 more 27" 144 Hz monitors.

I'm really into 3D.

It's why you need to set at the right distance from the screen in a 3D movie to get the full effect.  

Sit so the sides of the screen are out near your peripheral vision limit so that the edges of the screen don't cut off the image too much, and you will really feel like you are in it.

If you see the edges of the screen too far in, like I do my monitor, everything looks like it goes in, like looking out of a window, but only things near the center area look like they stick out at you.

If you shoot a mime, do you need a silencer?
