Morphology

night + blindness

The meaning 'difficulty seeing in dim light' is directly and compositionally derived from 'night' (the period of darkness) + 'blindness' (loss or severe reduction of sight); there is no idiomatic or metaphorical shift. This straightforward compound follows common cross-linguistic patterns, so a B1 learner who knows both constituents should be able to infer the MWE's meaning.

Etymology

Night blindness is a compound that joins night and blindness to paint a simple picture: someone who is 'blind' when the light is low. So, the term means 'difficulty seeing in dim light'.
