Every day, your five senses bring you information about the world. But they are not equal partners in the job. Eighty percent of the information your brain gets comes through your eyes, unless you are blind.
Yet, in a sense, your eyes do not see. They basically collect light. Your brain turns the collected light into images that make sense. In other words, what you “see” with your eyes has no meaning to you until your brain makes sense of it.
Your brain also lets you “see” events from the past. You may recall last year’s birthday party. You can imagine scenes that have never been. Can you “see” yourself being elected president? Even someone who goes blind in later life can recall visual images, thanks to the brain.
So, we know the brain plays a major role in the sense of sight. Still, the eyes are super important. Without them collecting light, the brain would have no raw material to work with.
