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

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.

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 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.

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.
