"Though Oedipus' future is predicted by the gods, even after being warned by Tiresias, he cannot see the truth or reality beforehand because his excessive pride has blinded his vision…" Only after Oedipus gouges out his own eyes, physically blinding himself, does he gain prophetic ability, as exhibited in "Oedipus at Colonus".It is deliberately ironic that the "seer" can "see" better than Oedipus, despite being blind.
