Kristen Stewart had to wear contacts

The ‘Spencer’ star followed the character description of Bella Swan to every tiny detail for the film adaption of the book and that included making her naturally green eyes brown through the use of contact lenses.

And Kristen certainly suffered for her art because she lothed wearing them.

During the media tour in 2011 for ‘Breaking Dawn: Part 2’, she said: "That is one thing I can't wait to say goodbye to is the contacts. [They give you] dead face.”
