"She turns her blessed eye upon me now, / And I'll endure all storms before I part with't" (II.i.50-51).

These are Deflores's words, but they seem to apply to all of the main male characters in Act II. Deflores, Alsemero, and Alonzo all seemingly have a defective perception of the world, highlighted by the motif of the eye/seeing that dominates the first two acts. Deflores can not help but gaze upon and endure the disdainful gaze of Beatrice. He also mistakenly perceives her intentions, believing she will bed and marry him for killing Alonzo. Alsemero falsely believes that murdering Alonzo will solve his love woes; he fails to see the consequences of such actions, and through this failure gives Beatrice the idea to employ Deflores, a plot that can't help but end horribly. Alonzo, despite his brother's watchful eye, is blind; he just doesn't want to see that Beatrice is in love with someone else. The eye has been very important thus far, and I'm interested to see how perspective will affect the madhouse subplot as well.
