The Blind Spot

There is a hole in your eye. Not a wound — a gap that was built in, on purpose, from the beginning. Right where the optic nerve punches through the back of your retina and runs toward your brain, there are no light-sensing cells at all. A circle of pure nothing, sitting in the middle of your vision, always. You have never once seen through it. And you have never once noticed it. That is the stranger part. Your brain decided, without asking you, that a hole in the world would be inconvenient. So it filled the gap in. It looked at what was around the edges of the hole and painted something plausible over the missing piece — a colour, a texture, a continuation of whatever happened to be nearby. It does this every moment of your waking life. You are not seeing the world. You are seeing your brain's best guess about the world, smoothed over, cleaned up, and quietly censored. The blind spot is just the place where you can prove it. Every other part of your vision is the same lie, only better hidden. The question that nobody fully agrees on: if the brain fills in the hole so perfectly, what else is it filling in that you'll never be able to find?
