Blindness- A Disability or an Advantage?

In Oedipus, Tiresias's blindness stands as a symbol. It is often said that when one of the senses is taken away, the others are heightened.  It creates a mysterious, ominous  feel about the character, and demands respect when he is still brilliant. In Tiresias's case, although he lacks vision he holds a certain cognitive state and is not intimidated by Oedipus or scared to go against him. 

Tiresias's blindness is also ironic. Although he can not literally or physically see, he can "see" the supposed corruption Oedipus has a part in, and can "see" all the king's wrongdoings and crimes, as well as the future. While Oedipus mocks Tiresias's blindness, like a bully picking on someone who is half his side, Tiresias instead fires right back, mocking the king's metaphorical blindness. While Oedipus taunts that the old man "can't hurt [him] or anyone else who sees the light (1382. 427)", the prophet claims that with "[his] precious eyes (1383. 470)", the king should not be ignorant to the fraudulence in his own accomplishments. He claims the king is blind to the corruption of his life, his family, and how he came to be how respected he is. 

Although Tiresias is lacking one of his senses, he also implies that Oedipus is lacking honesty. While Oedipus immaturely mocks Tiresias's blindness, he in return mocks the Kings greatness, calling it nothing but a scam.
