Sight and blindness
Sight and blindness are themes that play an important part in the play and constantly reoccur throughout the play. Sophocles uses this as a form of dramatic irony. They refer not only to literal but the metaphorical aspect of the words. The play is centred on this as it is because of Oedipus’s blindness that he ends up physically blind. This is quite ironical and to a certain extent makes you sympathise with him. Sophocles lets the audience know before Oedipus so that they get involved and engaged as the play unfolds. He leaves the audience to decide for themselves if Oedipus could have prevented his prophecy from being fulfilled.
Firstly one must look at the definition of blindness. Blindness is defined as unable or unwilling to see, perceive or understand. This is exactly what Oedipus displays on many occasions that even though he is regarded to be a wise and intellectual man as he solved the riddle of the sphinx he is not willing or able to see the truth of his life. The reasons for this are due to his Hubris and Hamartia, the one tragic flaw that all Greek tragedies incorporate. In Oedipus’s case it was his arrogance and pride that lead to his blindness. His flawed judgement and ignorance to the truth are a result of his characteristics.
