Eyes are a metonym for perception in Much Ado About Nothing, which means that the word "eye" is often mentioned by a character who really means by it any kind of perception, not just sight. Eyes come up especially often whenever one character’s perceptions are being influenced by another character’s tricks. Leonato, for instance, says that Benedick and Beatrice have got their “eyes” for each other from other characters; he means that they see each other a certain way (adoringly) because he and the others have tricked them into it. Borachio deceives the eyes of Claudio and Don Pedro when he poses with Margaret at Hero’s window. At one point in the play, Claudio asks the rhetorical question “Are our eyes our own?” In Much Ado About Nothing, the answer to this question is often no.
