How much of your nose can you see? This is my POV

For those confused. The yellow is the view from one eye blocked.

So the clear in the center is what both eyes see. The yellow on the RIGHT is what the LEFT eye has blocked, and the opposite for the Left of the image being what is blocked for the right eye.

But the center is blue while the sides are natural colors.... And even blocking an eye, I can't see anything remotely like you're describing.
- The center is not blue, the furniture is. There is very-much-so a yellow seethrough pattern around the outside of the image.
  
  While my personal view of the world has my nose a lot further down and not nearly as in the way, its probably because of my genetics and face makeup.
  
  If this image is truly to-shape and not just a picture to describe the concept, this persons nose is relatively forward compared to the tip of their eye and the upper ridge of their lip would be pronounced enoughto block vision.
  
  Assumedly though, this image isnt a real trace of someones vision.

Are your eyes at the same level as the bottom of your nose? Are you Stevie from family guy?

Stewie. Not stevie.

My wife has a notably tiny nose, like can't wear sunglasses without the pads that stick out or they fall off, and she can still see some of the bottom of her nose. So someone seeing nothing at all would have an incredibly small nose.

I can absolutely see the same as what you see there. The brain's pretty good at blocking stuff out like that in general. Between my nose and my glasses frames, it's amazing how I mostly go through the day ignoring impeded vision.

Add to that the blind spot right in the middle of each eye that the brain just kind of doesn't care about. It's pretty amazing, but it's also useful for thinking about consciousness and what it isn't. I.e., the missing info isn't like a hole in the screen of a movie. Unrepresented info just... isn't. That can help us get over the misconception of a "mind's eye" that's somehow watching the movie of your inputs playing out in your brain (which, logically, was always just a "turtles all the way down" trap/fallacy, anyway).
- Your blind spots aren't in the middle of each eye. They're offset or else you wouldn't see what you're looking directly at. You wouldn't be able to read. In fact, the center of your eye is the fovea which has the highest density of cones in the eye.

  The blind spot is where the optic nerve enters your eye.
  
  There are online tests that show you where your blind spots are. It works even on your phone, but you have to hold your phone just 3-4 inches from your nose, not the 10-12" like on a monitor. It's fun to see the circle completely disappear.

  I get visual migraines and the onset of one presents as a blind spot right in the center of my vision, and I can't read. It's interesting to watch it evolve and see what my brain fills it in with. At first it just looks like your regular blind spots. My brain fills it in with surrounding colors, but as it expands and moves off to the side, it becomes a shimmering, crystalline, spiral rip in the universe.

Do you have two noses on either side of your face or something?

How many eyes do you have?
Do you have a single eye directly above your nose?

I can't see my nose at all.

I don't really understand the image you shared, but I would imagine that people with flatter noses might see them less than those of us with pointier noses.

Close your left eye and notice your nose in relation to your bedroom. Now close your right and do the same. Now take a picture of your bedroom and draw the two sides of your nose roughly how they looked with each eye closed.

If I look straight ahead, I don't see any part of my nose. I don't know if that is because it's small enough that it does not cross my vision, or if I am merely so accustomed to it I can't even actively see it without actually pointing my eyes at it.

Simply put: Your brain has learned to ignore it completely, or nearly completely.

The simplist and probably inaccurate way I can show this: Look to your left and right with both eyes. You might see something of your nose, though it mostly appears invisible. Now close one eye and look in the direction of your nose. You can see it, as you would expect. So it's there and quite in the way.

  If I just look left and right without also looking down, I still don't see my nose. I see the bridge; but not the rest of it.

My nose blocks the lower third of your picture. It’s amazing how our brains just ignore it isn’t it.

I can barely see it if I look forward. If I look down though it takes up the entire side edge of my vision.

Look over your nose, not down at the floor
