How does the theme of blindness manifest in the play?

The theme of blindness in "Oedipus Rex" represents much more than just physical sight; it symbolizes a profound lack of insight and self-awareness. Oedipus, though he possesses the ability to see, is blind to the truth of his own identity and the reality of his situation. Throughout the play, he is unaware of his role in the prophecy that foretold he would kill his father and marry his mother.

This metaphorical blindness highlights the limitations of human understanding and the consequences of ignorance. Oedipus's journey is a tragic exploration of how one's inability to perceive the truth leads to devastating outcomes. By the end of the play, when Oedipus becomes physically blind as a result of his self-inflicted pain, it ironically reflects his realization and acknowledgment of his previous blindness to his fate.

In contrast to the other options, such as the notion that blindness only relates to physical sight or that it is a minor theme, the correct interpretation emphasizes the deeper significance of perception versus reality, underscoring tragic irony and the potential destruction that arises from a lack of self-awareness.
