Oedipus's vision, in terms of his overarching objective of ridding Thebes of its plague is evident from the beginning of the play. Oedipus has already initiated the process of looking for solutions by the time the priest arrives asking for help. Indeed, he has already dispatched Creon to Delphi, to seek advice from the oracle of Apollo about the measures that should be taken. When Creon enters, Oedipus begins questioning him intensely, declares a search for Laius's murderer, and asks for Teiresias's help, which he ironically spurns upon hearing Teiresias’s accusations. Ironically, even though Teireisias is blind, his vision is the clearest of all. Oedipus’s utter rejection of his words is an early indicator of how blind he truly is to the truth, despite his apparent clarity of vision. When a member of the chorus offers information, Oedipus tells him to "declare it then and make thy meaning plain." Ironically, even though he has a clear vision, in terms of his purpose of vigorously seeking the truth, he is utterly blind as to what that entails.
