This is one of several "Agent Smith" sunglasses worn by the cloned agent during the large fight scenes. These particular ones were not worn by Hugo Weaving, but by the many double stand ins dressed as him.
These items were used in Matrix Reloaded and Matrix Revolutions as the movies were filmed back to back and are instantly recognizable as the infamous Agent Smith.
