The Hole in the Middle of Everything

It feels like you are seeing a wide, sharp, continuous world. You are not. Only a tiny patch at the very centre of your gaze is actually sharp — hold your thumb at arm's length, and that is about the size of it. Everything else is blur and educated guessing.

To cover this, your eyes flick several times a second, snatching sharp little samples — and during each flick you go briefly, completely blind. You never notice the blackouts; the brain simply paints over them, splicing the scraps into something that feels seamless and whole. There is even a literal hole in each eye, where the nerve punches through and no light is caught at all. Your brain fills that blind spot in too, inventing whatever it guesses should be there.

So the rich, stable, panoramic scene in front of you is mostly a fabrication — a few sharp fragments and a great deal of confident guessing, stitched into the illusion of an open window.

And if your eyes catch so little — who decides what's worth showing you?
