What part of the brain stops them from seeing different locations? And is it possible for the eyes to do so?

Your eyes stay aligned so that they can see an object from two *slightly* different angles, and therefore judge the distance.
This is common to many predatory animals: cats, humans, eagles, ….
Prey animals (cattle, pigeons, rabbits) have eyes on each side of their heads to allow 360 degree vision to detect, if not judge distance to, a predator.
gah! i wish i had my notes from Perception in undergrad. I could tell you exactly why, but that was 12 years ago and I can no longer recall. Not helpful, I know. I think parts of it have to do with the occipital lobe and how all the stuff gets filtered in and processed by the brain. Super fascinating and deep- I’ll bet a neurologist could answer this better. Good luck!
While vision occurs in the occipital lobe of the brain, coordinating eye movements and maintaining fusion occurs in the midbrain (the pons) and is “involuntary.” That is, unless your name is Marty Feldman, your brain is always working to keep both eyes focused on the same object at all times. It’s a complicated process, much of which I have forgotten the details of since I took neurology in Optometry school.
