Every day, your five senses bring you information about the world, but they don’t share the load. Eighty percent of the information your brain receives comes through your eyes—unless you are blind.
Yet, in some ways, your eyes don’t really see. They just collect light, and it’s your brain that turns all that collected light into meaningful images. In other words, what you “see” with your eyes has no meaning to you unless your brain makes sense of it.
Your brain also lets you visualize events from the past, like last year’s birthday party. It lets you imagine scenes that have never been, like your being elected president. Because of the brain, people who become blind in later life can still recall vivid visual images in their mind’s eye.
Although the brain plays a major role in the sense of sight, still, the eyes are very important. Without their remarkable ability to gather light, the brain would have no raw material to work with.
