"Actress Mila Kunis was blind in 1 eye"

We'll ignore the tetchy implications that it was right around the same time Mila Kunis regained sight in both of her eyes that she also reportedly happened to split with longtime beau Macaulay Culkin, but the fact remains:

The Black Swan star used to be partially blind.
Kunis revealed the shocking news in an interview with Cosmopolitan, telling the mag that she worked hard to keep her partial vision a secret until she finally got it fixed last year.

"I was blind in one eye for many years, and nobody knew," she said. "I'm not blind anymore. I had surgery a couple of months ago. They cut it open and dropped a new lens in there."

Milena "Mila" Kunisan American actress. Her television work includes the role of Jackie Burkhart on That '70s Show and the voice of Meg Griffin on the animated series Family Guy. She has also played roles in film, such as Rachel Jansen in Forgetting Sarah Marshall, Mona Sax in Max Payne and Solara in The Book of Eli. In 2010, she won the Marcello Mastroianni Award for Best Young Actor or Actress at the 67th Venice International Film Festival for her performance as Lily in Black Swan. She was also nominated for a Golden Globe Award for Best Supporting Actress and a Screen Actors Guild Award for Outstanding Performance by a Female Actor in a Supporting Role for the same role.

So what caused the frightening vision decline in the first place?

Chronic iritis. The 27-year-old suffered from a chronic inflammation of the iris, which typically results in blurred vision, sensitivity to light and motion sickness.
