Camilla Belle with blue eyes
Generally I'm not in favor of people deliberately changing their eye color with contact lenses. It's because I don't like the fake aesthetics behind it.
However, in Camilla Belle's case, once I saw her with blue eyes instead of her normal dark brown eyes, I had to agree, she did look much more attractive and alluring. I was more inclined to look at her face with blue eyes than I did when she goes about with her normal dark eyes. I guess it's true, the eyes have it.
