 The sunglasses that Tom Cruise (qv) wears at the climax of the  climbing scene providing him with his mission brief are modified  Oakley Romeos that are now discontinued. They were modified for  their appearance in the film in three ways: the ear stems are  different (the commercially available model had curved ear stems  while the movie version has straight stems), the lenses used in the  film arent mirrored (to prevent the film crew being seen in the  reflection) and the most obvious modification being the earpieces  grafted on to the frames.
