Old Focals Architect - Hayley Atwell - Agent Carter
Old Focals is famous for providing characters in films and tv series with vintage sunglasses and recently they even create their own models which make it on to the screen.
In the case of the red sunglasses of Marvel's Agent Carter, Old Focals took their Architect model, dyed it red and added green UV lenses. Due to high demand of these glasses after apearing in the tv series, Old Focals now offers the possibility to order the same model but it is so popular that there is currently a waiting list.
