Morphology
The meaning 'the central part of the lens' is directly and compositionally derived from combining 'lens' (the eye structure that focuses light) with 'nucleus' (a central/dense region); this is a straightforward part-whole noun+noun construction. Although somewhat technical, the logic is transparent and cross-linguistically common, so a B1 learner who knows both constituents would readily infer the MWE meaning.
Etymology
The term lens nucleus names the very centre of the eye's lens. The word lens is the clear part of the eye and nucleus comes from a word meaning a small 'core' or 'seed', like the middle of a fruit, so together they mean the 'central part' of the lens.
