Most people have a dominant eye, and while it uses its non-dominant eye in tandem with the dominant eye most of the time, the brain, being an expert in eliminating redunant information, ignores the images received from the non-dominant eye. However, with special training or practice most individuals can force the brain to temporarily switch to receiving images from their non-dominant eye, even to receive images from both at once, resulting in a blurred chamelion-like or image.

Some individuals however, have a non-dominant eye so weak, that not only does the brain ignore the images it sends, the eye it self no longer moves in tandem with the dominant eye. This is known as strabismus or Lazy eye.

My question is, if the eyes are capable of not moving in tandem in those people, why can't we all train our eyes to move independently, and couldn't we also train our eyes to focus on two different images (on opposite sides) at once?

    $\begingroup$ I edited your post to remove the alien reference. While I, and maybe others may think it's funny, many users of this forum will disapprove and possibly downvote your question. They do have a point in not wanting the forum bloated with humor. [This comment to be removed.] $\endgroup$ – bpedit Oct 8 '16 at 20:47
  • $\begingroup$ @bpedit well couldn't you have least edited it, not simply remove it? I wanted to know if people with strabismus could see like chameleons. $\endgroup$ – doctorwho Oct 8 '16 at 21:18
  • $\begingroup$ What are your sources on this information? Note that stereoscopic vision is lost entirely with only one dominant eye doing the work. I.e., ...couldn't we also train our eyes to focus on two different images (on opposite sides) at once? is the very basis of binocular vision. I quite frankly don't understand your question. $\endgroup$ – AliceD Oct 12 '16 at 20:30
