Blindsight - Wikipedia
Blindsight is the ability of people who are cortically blind to respond to visual stimuli that they do not consciously see due to lesions in the primary visual cortex, also known as the striate cortex or Brodmann Area 17. [1]

‘Cortical blindness’ | The Visual Brain in Action - Oxford Academic
However, surviving pathways appear to provide sufficient visual information to allow the brain to mediate a range of visual tasks in the absence of such awareness. In this chapter, the authors discuss how ‘blindsight’ should not be characterized as ‘unconscious perception’.
