How does binocular vision work?

[bobze]

I have binocular vision so I decided i could help.

I can easily stare at one object and make it split into two and back into one. The longer the object may be, the harder it is to split. If you don't have it you can simply do this: Stare at one object, close you left eye and keep staring, then shift by opening your left eye and colosing the right. Notice the object moved becuase your eyes have different views. I can look at an object in two different views and yes the both look the same.

This isn't "binocular vision", this is double vision-Called Diplopia. Its not a special ability that people have, anyone who can "cross their eyes" can do it (ie; most people). However, in cases where it isn't purposefully done it can be sign of dangerous medical problems (or one too many drinks at the bar).
