McDaniel has an artificial blue BrightOcular iris implanted in her left eye to achieve the appearance of heterochromia, a condition that causes one's eyes to be different colors. She denied this fact but her father clarified that her natural eyes color is brown, providing her childhood photos. Journalists also pointed that her "blue" eye varies greatly on different photos and selfies, from blue-green dappled with brown, turquoise with a brown ring around the pupil, to solid aquamarine with a black ring at the perimeter.
