Family Eye Resemblance

In media, characters frequently have a Strong Family Resemblance to other members of their family, often down to a Hereditary Hairstyle. But sometimes creators go for a more subtle hint of relation: and since Eyes Never Lie, what better thing to do that than by giving the whole family very distinctive peepers?

Frequently, people who knew the parent in question will remark that the character has their mother's/father's eyes. In some cases, people can figure out who the family is from their eyes alone! Oddly, this occurs as often (if not more so) with Common Eye Colors as it does with Technicolor Eyes; this is usually justified by the eyes exhibiting some kind of expression or intensity that the parent shared.

Examples of Family Eye Resemblance include:

Anime and Manga

Fullmetal Alchemist: Ed has his father's eyes. The manga reveals that it is a mark of Hohenheim being ethnically Xerxian; i.e., belonging to a lost civilization.
- When Armstrong is introduciing his tiny little sister, who claims that she has the same eyes he does. It's the ONLY thing she has in common with him, appearence-wise.
