What is blindsight condition?
Blindsight is defined by the Oxford Concise Dictionary as “Medicine: a condition in which the sufferer responds to visual stimuli without consciously perceiving them,” implicitly referring, of course, to human patients. The historical origins, however, stem from animal research and neuroanatomy.

Can blindsight patients see?
Blindsight patients can detect, localize, and discriminate visual stimuli in their blind field, despite denying being able to see the stimuli. However, the literature documents the cases of blindsight patients who demonstrated a preserved degree of awareness in their impaired visual field.
Does blindsight let you see invisibility?
