I watched this movie in the late 60’s early 70’s. It was one of those late night black and white movies. Probably science fiction. Might have been British. People are turned into robots/androids.cyborgs. The men  wear 60 style suit and ties with hats while the women wear some kind of shiny black outfit. They are both controlled by the black military style glasses they wear. They are being used to kill people. A detective gets a hold of the glasses and puts them on, they control him and take him to headquarters/lair where the controlled people are working in an  office.
