What sunglasses did Denzel Washington wear in the great debaters?

There's no definitive answer to what specific sunglasses Denzel Washington wore in The Great Debaters. While his character, Melvin B. Tolson, does wear sunglasses in the movie, they are never featured prominently or identified in the film or behind-the-scenes information.

It's possible the sunglasses were a generic prop item chosen for the film, and there's no specific brand or model associated with them.
