In the phenomenon known as blindsight, some people who have been diagnosed as completely blind after damage to their visual cortex nonetheless retain the ability to make judgments and take actions that appear to require or demonstrate the use of sight. Despite the fact that they consciously see nothing, such individuals might, if prompted, catch a ball thrown, walk around obstacles, or guess with unusual accuracy whether an array of dots is moving or stationary.
