One of the main themes in Oedipus the King is blindness. Not just physical blindness, but intellectual blindness as well. This issue is an effective contrasting method for Oedipus at different points in the play. By saying "blindness", however, is a little misleading. It can be broken down into two sections: Oedipus's ability to "see", and his willingness to "see". The word "see" can be used in both contexts. Throughout the play, these two details are always at the center of the play. In the beginning of the play, Oedipus has perfect sight or vision. However, he is blind and ignorant to the truth about himself and his past, which relates to the idea of "truth v.s. appearance". He desperately wants to know, and to understand, but he cannot. At this point, it is obvious what Oedipus's action must be to overcome the blindness. Ironically, into the play is introduced a prophet, Teiresias, who is physically blind, but who has great mental power. This justifies Oedipus as a man ignorant to the true appearance of things - this blind man can "see" the truth about Oedipus, yet Oedipus, in all of his physical perfection, cannot.
