- In one of the ElfQuest stories from "Hidden Years", the human couple who Tyleet befriends are at first amazed when Tyleet tells them she's pregnant, because she looks like a child to them (canonically, Tyleet is older than most trees). Then the man points out that they should have known by Tyleet's eyes.

- In Come and See, the protagonist, a young boy enlisted in the Belarusian army to fight the Nazis, quickly becomes traumatized by the horrors surrounding him.

- In Use of Weapons, a character notices how the while the protagonist looks like a young man, a glance at his eyes indicates someone much older and wiser, and gives a hint at his Dark and Troubled Past. It seems though like this might be true to a certain degree of everyone in the Culture, even if they haven't had troubled lives — a rather spoiled and beauty conscious character in Excession notes that she can tell how the difference between a rejuvenated person who is actually a couple of centuries old and someone who is actually in their 20s or 30s.

- Elves in Lord of the Rings, are Really 700 Years Old, but Círdan is so old (11,000 years old at the end of the Third age, to be exact) that he even has grey hair and a beard, both extremely rare in elves. His eyes, however, are described to be "keen as stars", making him an inversion of this trope.
- Played very much for "creep factor" in Maggie Stiefvater's Lament. The faerie Queen is thousands of years old, and though she has the face of a pretty young girl, her eyes reveal not just her true age but also her evil.
- People are sometimes startled by the appearance of the eyes of the title character of Casca: The Eternal Mercenary. In this case it's a combination of both trauma and Really 700 Years Old, since he's spent the vast majority of his cursed existence as a soldier.

- Inverted in Babylon 5: When Sheridan becomes "unstuck in time" in the two-part episode "War Without End" , and his consciousness ends up temporarily inhabiting the body of Sheridan 17 years later in a Centauri prison cell with Delenn, and he asks her what is happening, Delenn realizes that what he told her of this timeflash incident later was true, because she sees that his eyes still had an innocence that had long disappeared in the intervening years.
