They say that eyes are the first thing you notice about a person's face. But if that's true, we wouldn't have been so surprised by the peepers below.

Strangely enough, we've never noticed how different and beautiful some of Hollywood's eyes can be. In fact, we've learned that several stars from the worlds of film, television and sports have a condition known as heterochromia iridis, which affects the coloration of their irises. Some cases are far more pronounced than others, but all are somewhat rare — and frankly, kind of cool.
So perk up those eyes and get ready to be amazed at the celebrity gazes staring back at you from such famous faces as:
Kate Bosworth usually wears contacts to hide her heterochromia on film. But when she took the role of Lois Lane in 2006's "Superman Returns," director Bryan Singer told her not to bother. "[He] wanted to keep them the way they are. So now the Lois Lane dolls have different colored eyes," she once told The Sun Herald.
Speaking with Cosmopolitan magazine in 2011, "Oz the Great and Powerful" actress Mila Kunis revealed that she developed her mismatched eyes while struggling with chronic iris inflammation, which also left her with cataracts and poor vision. "I was blind in one eye for many years, and nobody knew," she said. Kunis eventually had a new lens surgically implanted to correct her sight.

Max Scherzer of the Detroit Tigers was born with blue eyes, according to his mother Jan. "Then he was four months old. I looked down at my baby, and he had a blue and green eye. Very clearly," she told the Kansas City Star. "I have pictures and everything. I took him to the pediatrician shortly after that, and he said, 'They may go back and forth. They may change again this year.' As the year went on, the blue eye got bluer, and the green eye changed to brown."
"Star Trek Into Darkness" actress Alice Eve was appearing on "Conan" when the host pointed out her heterochromia, and Eve claimed that an ex-boyfriend failed to notice her mismatched eyes for nine months. "He was like, 'Do you have different colored eyes?' and I was like, 'Are you joking? What have you been looking at, nine months in?'"
When asked about his "fantastic eyes" by a red-carpet reporter, "Dallas" actor Josh Henderson admitted that they were always a topic of discussion. "It's kind of like a give and take," he added, revealing that he's almost blind in his left eye without contacts.
Kate Bosworth isn't the only Superman alumnus with heterochromia. The condition also appears in "Man of Steel" star Henry Cavill's left eye, which is both blue and brown.
When actor Simon Pegg revealed he had a special condition called sectorial heterochromia on the UK variety show "The Sunday Night Project," the show's hosts didn't know what that meant. Pegg then explained that his eyes were "mostly blue-gray, but in my right eye, I have a flash of brown." One of the show's regulars replied, "The long name makes it sound impressive, but when you described it, it sounded really dumb."
Honorable Mention: David Bowie
Although not technically heterochromia, David Bowie definitely has a unique set of eyes. In "Bowie: A Biography," the musician told writer Mark Spitz that he and a childhood friend had a fight over a girl when they were around 14, leaving him with a permanently dilated pupil in his left eye. (In the bio, both Bowie and friend George Underwood remember winning a date with the girl before the other.)
