目

How it works

を (object) marks 目め (eyes) as the thing being acted on, and the verb 閉じるとじる (close) shifts to its て (te-form) form 閉じてとじて (close). On its own, a te-form like this works as a soft, casual request — “close your eyes” — gentler than a blunt command. The subject “you” is left unsaid; the situation makes it clear.
