Looking at a horizon is likely a parasympathetic activity that is soothing and beneficial for eye movement.

“you're like your parasympathetic versus sympathetic nervous system that we just haven't quantified yet yeah i would guarantee it like it you have to be in a safe environment to be able to like look around and like look to a horizon yeah yeah that's that's probably a very parasympathetic thing and i think in some ways it's quite soothing to be able to see a horizon to move the eyes in that way”

“as i'm myopically focusing in on something say a screen in front of me or a wall in front of me that cues me up to go more into that executive function kind of like get up and atom type place in a little bit more like sympathetic type place as i take in the whole room or take in you know the panorama taking the horizon it sends the cue into my physiology it's like okay obviously paul's not under attack right now or he wouldn't be taking in the whole panorama”

“focusing far away activates your calming parasympathetic nervous system the rest and digest nervous system”

“but even better would be get outside view a horizon let your eyes sort of not sort of let them relax so that you're not looking at one particular thing for too long and you'll notice undoubtedly a pretty major State shift to a state of more calm”
