I pretty much grew up with a camera in my hands. Even at an early age I understood that the eye and the camera see the world a bit differently. The eye may deliver information on everything it sees, but it’s the brain that determines our perception. One would think that we see with our eyes plain and simple, but “seeing” is actually a complex and fascinating process involving the brain’s ability to make sense of the visual world.
A complex neural network collects electrical signals from visual activity every viewing moment. It is then the brain’s job to decide how to process those signals to create a clear picture of reality. Much of the sensory information is blurry, because of external motion and a massive amount of rapid eye movements, or “saccades”, as we repeatedly “shift our gaze.” Because these images with motion would be disorienting to see, the brain eliminates them from our final view. As a result, we are literally blind for about 40 minutes a day so that the world we “see” isn’t full of images that would make us dizzy or disoriented.
