the brain's confident guess about photons it mostly never actually sees clearly
means The faculty of seeing with the eyes, or — figuratively — the imaginative power to picture what could be, as in a plan or dream for the future.
from From Latin 'visio,' meaning 'a seeing,' built on 'videre,' 'to see' — the same root that quietly powers 'video,' 'evident,' and 'provide' (literally 'to see ahead'). It reached English through Old French 'vision' in the medieval period, carrying both the literal sense of sight and the loftier sense of a thing seen in a dream or trance — the prophet's vision long predating the CEO's.
