Morphology

light + adaptation

The meaning 'process by which the eyes adjust to high levels of light' is a straightforward composition of 'light' (the stimulus) and 'adaptation' (the physiological adjustment), so the MWE denotes adaptation to light. This NP follows normal English compounding/nominal modification patterns and has clear parallels in other languages, making it immediately comprehensible to a learner who knows both words.

Etymology

Light adaptation comes from the simple image of your eyes changing when they meet bright light: the pupil gets smaller and the eye makes an adaptation to protect itself and see better. That's why light adaptation means 'the process the eyes use to adjust to bright light'.
