Visual agnosia is like when you play a game of memory and you can't figure out where the match is. With visual agnosia, your eyes work just fine, but your brain has trouble recognizing and understanding what you are seeing. It is like the brain and the eyes are not talking to each other. This means that you might see something, but you don't know what it is. It can be hard to recognize things like people, animals, colors, or shapes.
