Morphology
The meaning 'unable to see clearly in bright light' is directly derivable from combining 'day' (the period of daylight) with 'blindness' (loss of sight); a learner who knows both words will naturally interpret this as blindness that occurs during the day. The formation follows a common and productive pattern (X + blindness = lack of sight in X) found across languages, so the expression is transparently compositional for B1 learners.
Etymology
Day blindness comes from the simple image of being blind during the day. Doctors called it this when people could see in low light but not in bright sunlight, so it means 'unable to see clearly in bright light'.
