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.
