Thousand-Yard Stare

A character who has just gone through some sort of trauma, learned something they probably didn't need to know, or seen something they really shouldn't have had to, will often have an unfocused, vacant stare into a vast abyss of nothingness, slipping into a shock and weariness from which it is very hard to shake.

Note that this trope describes the stare/facial expression itself, and not what causes it or anything related.

"Thousand-yard-stare" is believed to have originated in World War One, and was coined for the faces of battle-weary soldiers. Named for the perception that such stares really do seem to be able to see very far ahead. Eyes cross a little when focusing on something reasonably close, but eyes not looking at anything will behave like eyes looking at something very far away. Dull Eyes of Unhappiness can look similar to this, but they're chronic while this trope tends to be transitory.

See also Heroic BSOD, for what usually goes hand-in-hand with this. Not related to the 'Thousand Yard Stare of Impending Flashbacks', an affliction near universally shared by the characters of Lost.

Anime and Manga

 * In Azumanga Daioh, Chiyo does this whenever Yukari's driving is mentioned since she barely survived it.
 * Tsukune Aono of Rosario to Vampire has one halfway through the first manga season. It's desolate, and if it looks like he's given up... it's because he has. Cue Carnage and mayhem.
 * In Fullmetal Alchemist, Mustang and Hughes discuss it during the Ishbalan war. Hawkeye approaches, and Mustang laments that Hawkeye has the stare too.
 * I thought they just talked about all of them having killers' eyes....
 * In the Marineford arc of One Piece  oh God,.
 * in Thriller Park. It even got to the point of almost being a case of Died Standing Up until  speaks up and says "Nothing happened."
 * Vash the Stampede is prone to this expression when pushed far enough. Even leaving aside his Heroic BSOD after Legato's death, he will do this while smiling sometimes.
 * Nothing emphasizes his isolation from humanity better or more tragically than a sad-Vash thousand-yard-smile, especially if he's doing something like hugging Miss Elizabeth while she breaks down over his not being evil, after trying to blow up the town to kill him.
 * Rurouni Kenshin starts doing this when his angst level picks up late in the manga, though his first uses are after taking absurdly heavy damage in the Shishio arc. Maxes out during his especially persistent Heroic BSOD and Ten Minute Retirement to the slum of despair. Scares the hell out of everyone in its first major appearance right after Enishi formally declares his Jinchuu.
 * A less pitiful-looking version was also employed back when he was Hitokiri Battousai, aka Teenage Kenshin, and attempting to put off his moral crisis and shellshock for as long as possible so as to fulfill his duty.
 * In Naruto victims of the Tsukuyomi generally end up like this.
 * Gundam
 * Amuro Ray of Mobile Suit Gundam develops one after extended combat on Earth. Even a Bright Slap ain't fixing that. His recovery doesn't really start until the next series.
 * Chibodee Crockett of G Gundam has one while wandering around in a (somewhat violent) daze resulting from his clown phobia.
 * Kira Yamato of Gundam Seed and Gundam Seed Destiny looks like this following the conclusion of the Bloody Valentine War. He spends most of his time sitting on his porch, staring off into space, and flashing back.
 * Setsuna F. Seiei of Gundam 00 has a permanant one. Being an ex-Child Soldier will do that to a guy.
 * Asemu Asuno of Gundam AGE does this briefly after.
 * This serves as another deconstruction for Casca's post-Eclipse behavior in Berserk. After going through a very heinous ordeal of, Casca shows very realistic signs of   trauma syndrome, one of them being that she often vacantly zones off and stares at nothing. Prominently shown on the hilltop scene when

Film
"Payback: The thousand-yard stare. A marine gets it after he's been in the shit for too long. It's like... it's like you've really seen beyond. I got it. All field marines got it."
 * In Full Metal Jacket, Payback gives an extended speech about this.


 * Joker himself gets to do the stare after.
 * One of the soldiers on leave in Band of Brothers (the whole episode focused on various soldiers dealing with the sudden change from battle to civilian life) has this.
 * Commonly, the expression on some of the characters in Saving Private Ryan (indeed, the beginning graveyard scene ends with this).
 * Enforced Method Acting: The entire cast was run rugged, interminable military exercises - except Matt Damon (who plays Pvt. Ryan). It even made the cast resent Damon, which was entirely the point.
 * WWII veteran and b-movie star Audie Murphy, who saw many of his comrades in arms killed and is credited with personally killing, wounding or capturing more than two hundred Axis soldiers, had a particularly bleak and distant stare, which director John Huston put to good use in The Red Badge of Courage. Murphy developed a warmer and somewhat more animated screen persona around 1953, perhaps due to the birth of his beloved son Terry, but he never really lost the Thousand Yard Stare.
 * If there is a fetish for thousand-yard stares, the film version of The Road is your fuel.
 * Boogie Nights: During the scene at Rahad Jackson's house, a drug-addled Dirk stares into space for what seems like an eternity.
 * Invoked in Rambo, the fourth film in the series, when an Australian mercenary informs Rambo that he's seen the thousand-yard stare before. He's not impressed, but his opinion changes after the shit hits the fan.
 * In Animal Kingdom, Darren, the youngest Cody brother, develops one after
 * In District 9, Wikus has one of these in the back of a MNU van

Live Action TV

 * The Ace does this after being broken in the Mash episode "Heal Thyself." While compulsively scrubbing away invisible blood.
 * Some (canonical) DVD specials from Doctor Who have noted this about Rory Williams. He spent almost two thousand years guarding a box as an immortal centurion. It happened in a defunct timeline, but he still has the memories, which he must suppress for his own sanity, though as the Doctor points out "Sometimes you catch him just staring..."
 * He mentions that he can remember all two thousand years he stood guard, but he can't always remember it.
 * In Horatio Hornblower, Archie does this mostly in Series One. Being ruthlessly tormented by a shipmate followed by  and then getting caught up in someone else's war where the chances of survival/victory are extremely low will have an impact on a person.

Music
""That waitress at Pete's who took so long to seat you and left you to stand in the doorway. With her stringy red hair and her thousand yard stare, in her mind, she's the princess of Norway.""
 * Referred to in the song "Assassing" (sic) by Marillion.
 * Shown in the music video for "Ghost of You" by My Chemical Romance, much of which is set during the landings at Normandy during World War II. The music video ends with a shot of the lead singer's stunned eyes.
 * Referred to more humorously in Tom Smith's "Rich Fantasy Lives"

Professional Wrestling

 * Wrestlers who take powerful blows to the head are often described as having this, and it is usually an accurate description. Randy Orton, during his brief face run a few years ago, was involved in a story line where he was taking too many bumps to the head, and had this blank stare after each one.
 * In particular, Chris Benoit was described as having this for much of the last year of his life, outside of the ring.

Video Games

 * Part of the arena banter in Ratchet and Clank Up Your Arsenal refers to Ratchet having one of these, making him extra dangerous.
 * Adrienne Delaney at the end of Phantasmagoria as part of her Heroic BSOD.

Western Animation

 * In an episode of Spongebob SquarePants the eponymous sponge blanks out after receiving an improbable order. Mr. Krabs explains it as the thousand yard stare to Squidward, that he had seen it during the war.
 * Donald Duck's stuck with one at the end of "Up A Tree", after Chip n' Dale blew up his house into smithereens.
 * Used in Adventure Time frequently. Finn gets one in Susan Strong when he contemplates being the last of his kind for too long. He gets another one in "Marceline's Closet," when he sees Marceline naked.
