瞩目 is a verb-object compound (瞩 'stare' + 目 'eye') that means 'to fix one's eyes on' or 'to be the focus of attention'. It is most commonly used in set phrases like 引人瞩目 ('attract attention') and 举世瞩目 ('attract worldwide attention'). Although the POS is marked as v.o. (separable verb), in practice 瞩目 is rarely split in modern Chinese; it behaves more like a fixed literary verb. You typically see it in formal or written contexts, often with a passive meaning: something 'draws the gaze' of many people.
