 Why, in this case, is vision not suppressed? A team of visual scientists published a study of this question in the journal Nature. They found that what gets suppressed during a saccade are large areas of light and dark. Those are the perceptions that seem to contribute the most to a sense of motion. Finer details, like fenceposts, are not suppressed, maybe because there’s no need to suppress them rapid eye motions usually turn them into a blur anyway.
