A common Horror Trope. A character is surrounded in darkness, aware that there's something lurking just in the shadows. They stare inquisitively into the abyss... and then a pair of eyes appears and returns the favor.
Usually, this is used for Rule of Scary, but there's many other uses. For example, a comedic effect could be that the entity shrouded in shadow could be invisible except for their eyes.
By the Lights of Their Eyes is a Sister Trope. A typical trait of Things That Go "Bump" in the Night. Compare Glowing Eyes of Doom.
The trope title refers to one of the many philosophies of the eternally quotable Friedrich Nietzsche, featured as the page quote for He Who Fights Monsters.
Examples:

- My Little Pony: Equestria Girls:
- My Little Pony: Equestria Girls – Legend of Everfree: The intro sequence briefly includes a pair of glowing yellow eyes appearing in the darkness of the forest — and the camera just zooms on them. No explanation is given, but the shot is used to show that there's something ominous in these woods.

- Lone Wolf: An interesting variation occurs in The Kingdoms of Terror. Lone Wolf is being attacked by a very fast monster with glowing eyes in a pitch-black castle.

- In the Disney World version of The Haunted Mansion there is a point where the Doom Buggy is surrounded by demonic eyes that look around and blink. As it moves to an area with better lighting, these eyes are revealed to be designs in the wallpaper. What makes this especially strange is that some of the eyes in the dark section are closer than other nearby ones, and a few are even moving in 3D space.
- Journey into the Dark is an attraction from the Futuroscope that put you into the shoes of blind people. The only thing you'll ever see in the darkness is the glowing eyes of the Yeti at the end of the walkthrough.

- In Five Nights at Freddy's 4, Nightmare's kill screen is nothing but its piercing red eyes and razor-sharp teeth illuminating from darkness.

- Lakeview Valley has something that seems to be peering out of practically every tree hollow and sewer grate, offering your protagonist advice... such as encouraging you not to trust any of the locals, and tempting you to turn against your new neighbors in exchange for various perks.

These eyes keep appearing as Rarity and Pinkie walk along the path — up until Rarity snaps and yells at them, at which point the creatures scamper off.
- "Frenemies": Chrysalis is observed by numerous eyes peering from the trees, after which a mass of shadow comes up behind her, swallowing the path, and two massive orange eyes open within it to look at her... until Chrysalis roars at it and sends all the eyes' owners running away, smugly remarking that there's nothing around scarier than her.
- Star vs. the Forces of Evil uses this trope in the episode "Storm the Castle."

Apparently the monster's body makes sandwiches in addition to being full of glowing eyes.Talk about disgusting.

- Animals with a tapetum lucidum
can produce this effect in Real Life: if there's a dim light source (like a campfire) behind the person peering into the darkness, it may be bright enough to reflect off the tapetum and reveal the animal's eyes but not bright enough to make the whole animal visible. Nearly all nocturnal predators have a tapetum lucidum, because it improves their night vision, including all the ones that you really don't want to have lurking around your campfire...
