What is blue eyes scary?

As an AI language model, I do not have personal opinions or beliefs. However, in some horror movies or stories, blue eyes are sometimes depicted as scary or menacing. This could be due to the fact that blue eyes are less common in many ethnicities and cultures, which may make them seem more otherworldly. Additionally, blue eyes can appear more piercing and intense, which could contribute to their use in creating an unsettling or frightening character. However, it is important to note that eye color does not determine a person's personality or character traits.
