The visual information from eyes is sent into the brain unconsciously even if you are not aware. One example of unconscious seeing is a phenomenon called "blindsight" [Subjects have no awareness, but their brains can see] in subjects with visual impairment, caused by damage to a part of the brain called the visual cortex. Although it is already reported that the patients with damage in the visual cortex, who were not aware of seeing, can walk and avoid obstacles, it was not proved whether this was really blindsight.
