Morphology

pupillary + reflex

The phrase is directly compositional: 'pupillary' means 'pertaining to the pupil' and 'reflex' means 'an automatic response', so a B1 learner who knows both constituents can infer it denotes an automatic response of the pupil (e.g., constriction to bright light). It is a technical medical term but its meaning follows straightforward word combination and is cross-linguistically predictable.

Etymology

Pupillary reflex comes from watching the eye react to light. The black center, the pupil, becomes smaller as the colored ring, the iris, tightens without you thinking, so it means the eye's 'automatic' response to bright light.
