It should almost always be in my line of vision but I rarely see it. The fact that it is in my line of vision is borne out when there is something strange going on with it. If, say, there is an exceptionally shiny spot on it or if I have a cold and rub it raw, I can see my nostrils flaking. Which is really annoying so I can see why you wouldn’t want to see it all the time. But that doesn’t explain why I can’t see it all the time.
Someone should sell this nose-cloaking ability to our military.
Depending on the size you see it most of the time and just ignore it.
Maybe you’ve got a tiny nose?
I can see mine just fine, though I have to think about it so that I remember to not ignore it.
I say I’m not ‘ignoring’ my nose. I truly do not see it unless I purposely look for it. Just like Tranquilis who, when he looks for his nose, he sees it. It isn’t like this pen on the table that I am not using, so I’m ignoring it. I can still see the pen, I’m just not paying any attention to it. But my nose? It’s not there unless I want it to be.
Binocular vision, coupled with the brain just filtering it out. Close one eye, and your nose becomes quite visible…
Vision isn’t actually a matter of “just seeing something”–vision is a complex series of computations involving different parts of the brain (and even some of the processing done “in eye”) with various parts of the retina having different strengths and weaknesses. Details of what light actually enters your eye are edited out or even simulated as needed. So you ignore your nose because some of that code in your eyes or brain says “ignore the nose.”
(Some of the reading I mentioned in this thread may be helpful to you. And other examples.)
Closing one eye does make it visible! But the brain just making it disappear I find unsettling. I can’t see what is quite literally what is at the tip of my nose because my brain had decided I don’t need to see it. That brain, it’s tricksy.
Schrodinger’s Schnoz?
Did an uncle or grandfather perhaps steal it when you were younger?
An awful lot of what you see is your brain forming an image from a lot less, and sometimes more data than what’s hitting the rods and cones on your retinas.
You can’t “see” your nose, until you put your finger on it, then POOF it is very visible.
I bolded see, because i mean mentally seeing it not physically.
Some how we become unaware of it, which is probably good because it is hard to see anything else if you are focusing on your nose all the time.
I realized the same thing with glasses
At first the nose bar was like BAMM!!! what is this thing??
Now i dont see it anymore unless i try, or poke my finger at it.
Then i looked at myself in the mirror and realized the same thing 
What blows my mind is that each eye has a blindspot where the ocular nerve goes through the retina and your brain just constantly paints over the holes in your vision with an approximation of what the other eye sees at that spot. Freaky!
I’ve got it.
It probably helps the ignoring process that, if you’re focusing on almost anything else at all, the nose is badly out of focus.
The actual area of your visual field in focus at any time, is apparently only about as big as your thumbnail held at arms length. Your eyes are constantly darting about, filling in visual detail and your brain is weaving it together into a coherent scene. You will usually only notice things in your peripheral vision when they change. At least that’s my understanding.
Also remember that your eyes physically cannot focus on anything closer than 6" or so away. If they could there would never be a need for magnifying lenses.
Human visual perception of crammed full of weird stuff like that - we’re not really seeing out of our eyes like they were just a window, even though our brain reassures us we are - it’s more like our brain assembling a plausible rendering of the world based on a few snapshots, assumptions and pure fiction - a bit like one of those panoramic photo collages.
If you look at your own face up close in a mirror - look at your own right eye, then look at your left eye - you won’t see your eyes move - because your vision shuts down during the movement - but your brain doesn’t present you with a moment of black blankness - it just sort of fills in
this is the same reason that you can take a picture through a wire fence and not see any of the fence. You are focusing on something in the distance.
I can go one better. I can’t see my whole head. Everything else I can see but not my head.
Hmm… I must be weird, in that I can usually see my nose. My brain probably edits it out sometimes, but most of the time I’m aware of the two shadows of my nose in my peripheral vision. And I think I’ve seen it like that ever since I was young.
