Why is the world right side up?

[Al B. Sure!]

Somewhat related is an observation I've made as a contact lens wearer. If I remove one contact lens, you would imagine the myopic vision in one eye and corrected vision in the other would confuse my brain. Instead, however, the corrected vision over-rides the blurred, causing me to see perfectly well out of one eye including in the middle of the vision (equivalent to covering the other eye).

Giving it some thought, I did not consider that maybe I've always noted this while wearing a contact in my dominant (right) eye. I will have to see if the corrected vision is still somehow dominant if the lens remains in my non-dominant eye. If so, it makes you wonder how my subconscious knows to focus on the clearer image instead of treating them as equally valid.

And Lori, eye dominance causes those pentagons to not be symmetrical. Not that it changes your question but it's just a consideration.

[Al B. Sure!]

Nope eye dominance does not explain why corrected vision overrides myopic when I wear only one contact in either eye. The corrected vision in my left, nondominant eye still dominated.

I don't really follow. Inverted or not, the correspondance of the images doesn't change...



I'm more inclined with the senses aligned hypothesis. Also, with the fact that we couldn't really tell if down wasn't down. We'd always see 'down' as 'down', because that's what it would always bee to us.

Unfortunately, that article doesn't explain why right side up is what our brain considers normal, and that's what I'm asking.

Because walking with your feet on the ground is better than pogoing on your head. And you can sip your morning americano and walk and not scald your nostrils at the same time!


Except for Gerald Ford. Recessive genes ?

Australia on top - YES!

To elaborate, I'm only partially convinced by this answer because I'm not sure it proves anything more than that the senses need to be aligned, not that any particular alignment is better than any other.

You must be forgetting the part about how gravity imposes a particular directionality into our frame of reference.

[MrFun]

BAH! Gravity is "just" a theory.

I see you ascribe to the theory that the earth sucks.

You blowhole. Or are you more of an old geyser ?

Well, my other position on this is that my question might not even make sense. So there you ago.

When I play FPS I play inverted axis (both axes). I can play non inverted but takes time to get used to before feeling natural. Similar thing when driving reverse steer vehicles, it takes a while to get used to, but soon feels natural.

I think directionality of senses does make sense, but left is right and up is down interaction with the world could be adapted to. Who knows, maybe what you think of as right way up I would see as upside down.

[Dauphin]

Similar thought. When I looked at 3D pictures (where you stare through the page to see the image), I always saw the images as indented rather than popping out at me.

[N35t0r]

There's two kinds of those, and you can see them by either looking through the page or by crossing your eyes. One way you see them inverted, and the other way you see them the 'correct' way, but whih is which depends on how they were made.

[Dauphin]

Well, there is one kind, you should see an image by staring through or going cross eyed.
