Morphology
The meaning 'ability to see in very low light' is directly and transparently derived from combining 'scotopic' (relating to seeing in low light) with 'vision' (visual capacity). Although 'scotopic' is a technical term, the adjective+noun composition follows normal semantics, so a learner who knows both constituents would readily infer the MWE meaning.
Etymology
Scotopic vision comes from an old word for 'darkness' and gives a simple picture: scotopic means dark and vision means seeing. So it means 'ability to see in very low light'.
