UFO (TV series)
Notably for science fiction, the alien race is never given a proper name, either by themselves or by human beings; they are simply referred to as "the aliens". They are humanoid in appearance, and the autopsy of the first alien captured reveals that they are harvesting organs from the bodies of abducted humans to prolong their lifespans. However, the later episode "The Cat with Ten Lives" suggests that these "humanoids" are actually beings subject to alien mind control, and one "alien" body recovered was suspected of being completely "homo sapiens", "possessed" by one of the alien minds—a concept central to Anderson's previous Supermarionation series "Captain Scarlet and the Mysterons". Their faces are stained green by the hue of a green oxygenated liquid, which is believed to cushion their lungs against the extreme acceleration of interstellar flight; this liquid is contained in their helmets. To protect their eyes, the aliens wear opaque sclera contact lenses with small pinholes for vision. The show's opening sequence begins by showing the image of one of these contact lenses being removed from an obviously real eye with a small suction cup, even though the lens is not shown in contact with the eye. The entire lens-removal sequence is shown in the pilot episode.
