expression, godan verb (-su)
fix one's eyes on; stare intently at; study carefully with the eyes
Used when one deliberately directs and holds their gaze on something, often to examine or scrutinize it. The verb 晒す means 'to expose', so the expression literally means 'to expose one's eyes to something'.
彼は虫眼鏡で小さな文字に目を晒した。
He fixed his eyes on the tiny letters with a magnifying glass.
