The "tears" have been a kind of tradition ever since the original Kamen Rider. Not all Riders have them, but a lot do have some kind of black point or line coming down from their eyes (see Build for another recent example). If I remember right, they're a symbol of the Rider's sadness at wanting peace but needing to fight. And since Ark-One came into being through Aruto's grief at losing Izu, it makes sense that its tears would be huge!
