Natalie Portman's astonishing performance in the Black Swan has seen her pick up the best actress award at the Golden Globe awards, with contact lenses playing a key part in her appearance in the movie.
The 29-year-old scooped the gong for her role as Nina Sayers in Darren Aronofsky's latest film, which charts a ballet dancer's quest to play both the Black Swan and the White Swan in a production of Swan Lake.
However, the role required her to physically transform into the menacing Black Swan - a feat achieved through the use of special coloured contact lenses created by Oregon firm 9mm SFX.
Kevin Carter, who owns the company, told Oregon Live before Christmas: "They're soft contact lenses, regular day wear. We use a tiny paintbrush and we actually use dyes, not paint."
Portman's win at the Golden Globes has made her the favourite to repeat the feat at the Academy Awards next month and scoop her first Oscar.
