Step-by-step explanation:
I feel like the answer to this question is more or less an opinionated one. Also, I don't know if this a serious question either but as far as my opinion goes I would say some people may get creeped out by nonnormal eyes because it's not something they see every day and it is a main feature on the face. The movie "Coraline" for example creeps me out on a different level. I feel that the button eye idea in that movie is terrifying because I don't see that as normal. Of course, I see buttons as a sewing accessory which I why I found it wrong and scary that they used it in the movie. Also, black eyes or all-white eyes are generally associated with the horror category, ( dead people, ghosts, etc...)
I hope this helps!
Have a lovely day!
