Morphology

red + eye

The noun is directly composed from 'red' (a color) + 'eye' (the organ), so a learner who knows both words will naturally interpret it as an eye that appears red; the photographic cause (flash reflection) is a specific explanation but does not prevent understanding of the basic meaning. This simple adjectival + noun composition is cross-linguistically common (e.g. Spanish 'ojos rojos') and therefore immediately comprehensible to B1 learners.

Etymology

Red eye in photos comes from a camera flash lighting the back of the eye, which makes the pupils look bright red in the picture. That's why the red pupils in flash photos are called 'red eye'.
