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 for an irritated eye is simply a description: the eye turns red from tiredness, infection, or allergies. So calling it a 'red eye' points to the red, sore look of the eye.
