ABSTRACT
The eyes are given altogether too much credit for seeing. Their role in reading is frequently overemphasized. The eyes don’t see at all, in a strictly literal sense. The eyes look; they are devices for collecting information for the brain, largely under the direction of the brain, and it is the brain that determines what we see and how we see it. Our perceptual decisions are based only partly on information from the eyes, greatly augmented by knowledge we already possess.
