Black Swan star Mila Kunis has revealed a big secret in the February issue of Cosmopolitan magazine. She told the magazine she had chronic iritis, an inflammation of the iris. “I was blind in one eye for many years, and nobody knew,” Kunis, who was born in Ukraine when it was part of the USSR, admitted. “I’m not blind anymore. I had surgery a couple of months ago. They cut it open and dropped a new lens in there.” Kunis recently separated from longtime boyfriend Macauley Culkin after a nearly nine-year relationship, but that isn’t slowing her down. The magazine named her this year’s Fun Fearless Female.
