Morphology

Moon + blindness

The meaning is directly derivable from the constituents: 'moon' evokes night/dim light and 'blindness' denotes loss of sight, so a learner who knows both words can infer 'loss of vision in low light' or 'night blindness'. This compositional relation is straightforward and parallels the common term 'night blindness', making the MWE immediately comprehensible to B1 learners.

Etymology

Moon blindness may come from farmers who saw horses get eye problems that kept coming back after nights with a bright 'full moon', so they linked the trouble to the moon. That's why the term now means a repeated eye inflammation that can lead to 'blindness' in horses.
