The dedicated Kristen Stewart fans out there are likely very well aware that she wears colored contact lenses for her role as Bella Swan in the "Twilight" movies. And in "The Twilight Saga: Breaking Dawn - Part 2," Stewart dons the amber lenses her co-stars Robert Pattinson, Ashley Greene, Nikki Reed, Peter Facinelli, Elizabeth Reaser, Jackson Rathbone and Kellan Lutz have been wearing for years as part of their official Cullen vampire clan costuming.

When MTV News caught up with Stewart recently, we asked about that experience and she revealed that, although she's experienced with contacts, her new vampire ones weren't much fun to wear.

"They are worse. The yellow ones sort of limit your vision even more, and so you feel a little bit more closed off," she said. "That is one thing I can't wait to say goodbye to, is the contacts. They just kill you. [They give you] dead face."

Pattinson recently told us he was delighted that his co-star had to suffer with the rest of them. "She's like, 'I wear contact lenses. Why do you always complain about yours?' " Pattinson said. "When she finally wore them and then was complaining about them every second of the day, it was kind of satisfying."

Stewart said the yellow lenses were totally worth the trouble, because she was so excited to play the vampire version of Bella.

"I've been waiting. To see her thrive anytime, it's — she's always so full of something that she knows, and it's like, at this point, you finally go, 'Oh, she was right,' and she can also go, 'OK, great, I'm not crazy, this was supposed to happen.' "

Stewart said Bella's previous feelings that she was different from others are validated in the final film. "The whole vampire thing, I wasn't excited to be white and all that; I was really more excited to finally get her there, because she wants it so bad."
