When I try to rotate my eye, both of my eyes will rotate the same amount and in the same direction (obviously).
I'm wondering if it is possible to control each eye separately. I've never seen anyone that can do this (except some pics on the internet which I'm not sure if they are digital edits simply for fun).
Is it possible? If not, why? Is it because they are both controlled by the same nerve? Or is it simply because we are not used to it and it's super difficult (but possible)?
