Nevertheless, you can “see” your own blind spot by looking at the plus sign in the middle of the rectangle below with just one eye open. (You may need to take your glasses off.) Starting with the page about a foot in front of your nose, bring it closer while focusing on the plus sign. One of the black discs (the one on the same side as your open eye) will disappear at some point when the page is about six inches away, and will reappear as you bring the page closer still. The moment of disappearance tells you when light from that disc is falling on your open eye’s blind spot. Here’s a bonus: If you shift your open eye to look at the still-visible disc on the other side, the plus sign will disappear! You may have also noticed a strange occurrence at the spot where the disc lies. When the disc disappeared, it left no blank spot in the grid background. Your brain did something interesting—it filled in the scotoma with something that made sense, a continuation of the same grid that you could see everywhere else in the framing rectangle.
