Blindsight is a term used to describe a condition where a person can respond to visual stimuli without conscious awareness, despite having no conscious visual perception. Some synonyms for blindsight include unconscious vision, implicit recognition, and subconscious visual processing. Other related terms include non-conscious visual perception, perceptual awareness, and subliminal vision. Blindsight is often associated with neurological conditions such as stroke, traumatic brain injury, and degenerative diseases affecting the visual system. The study of blindsight has helped researchers better understand the complex nature of human perception, and may have implications for the development of new treatments for visual disorders.
