The phenomenon ‘blindsight’ has received much interest from neuroscientists, philosophers, and psychologists during the last decades. Several researchers seem to agree that blindsight might be of great importance in the ambition to find neural correlates of consciousness. However, the history of blindsight is a history of changing experimental paradigms and very few patients. In late 19th century, researchers debatedwhy lesions to primary visual cortex seemingly left some visual abilities intact in animals, while human patients reported to be blind. From the 1970s until today, experiments have attempted to compare measures of conscious and unconscious perception, suggesting a distinction between visual functions and visual experience. However, more recently, newer methods and an interest in introspective reports have cast doubts about the ‘blindness’ of blindsight. A cautious conclusion is suggested, though current research can be interpreted in different ways.
