Mila Kunis, the Black Swan star used to be partially blind.
Mila Kunis revealed the shocking news in a recent interview, telling 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."
So what caused the frightening vision decline in the first place?
Chronic iritis. Mila Kunis, the 27-year-old, suffered from a chronic inflammation of the iris, which typically results in blurred vision, sensitivity to light and motion sickness.
