Exactly What It Says on the Tin, this is when someone doesn't like to be looked at, with the title being the Stock Phrase you're most likely to hear them bellow to underline the point. Compared to Hates Being Touched, this one tends to be a more temporary state of being, often triggered by a Heroic BSOD, transformation into a Body Horror, or revealing a Red Right Hand - after all, it can be understandably difficult to write a character who actively seeks to go unnoticed. Such situations are often remedied with The Hero giving the afflicted Love Interest a Cooldown Hug and telling her that he still loves her, or that her wings are beautiful.
In a more mundane setting, this can be merely indicative of body image issues, warranted or otherwise. This version is almost Always Female.
Another version is a character being caught doing something they're ashamed of, for example if they've been Caught With Their Pants Down.
Not to be confused with the remarkably similar, defensive stock phrase said when everyone in the room labels a character as the most likely culprit of some misdeed of which he's not (entirely) guilty by leveling him an accusing stare — "Don't look at me!" rather than "Don't look at me!" — which is... another trope entirely. Nor is it to be confused with the also similar stock phrase where the characters are trying to figure out an explanation for a confusing or mysterious situation, and one who is Genre Savvy, believed to have special insight, or simply intelligent enough to figure such things out is looked to, only to respond this way.
Something to keep in mind when adding examples: it only counts as an example of this trope if it is used to imply that a character is ashamed of their appearance. It's not a example if it's yelled at an Accidental Pervert stumbling upon someone taking a bath.
Compare Hates Being Touched.
Fruits Basket: When Kyo's true form is revealed in front of Tohru, he yells this before he runs off.
In Fushigi Yugi, Miaka yells this at Tamahome, covering herself after nearly being raped. In a later four-paneled parody at the end of the volume, Tamahome does the same.
In Spice and Wolf when Holo transforms fully into her wolf form, she says this specifically to Lawrence. Notably, she didn't mind Lawrence seeing her stripping naked, but she didn't want to frighten him with the transformation.
Black Butler: In the anime, Sebastian tells Ciel to close his eyes when he transforms into his demon form in order to kill Ash - a surprising (and yet disappointing) non-romantic version of this trope.
A heartbreaking example occurs during the climax of the Eclipse from Berserk. During her horrific rape by the now demonic Griffith, the last sane thing that Casca says to her lover Guts is "don't watch," despite the fact that he is being Forced to Watch by the demons who dog-piled him after he severed part of his own left arm in his last attempt to save her. After she passes out from her defeat and humiliation, Casca awakens only to have become insane and mute and has not spoken coherently since the events of the Eclipse.
Was a pretty important moment for Jiro's mental state in Kikaider when he ran off screaming this.
Happens in the Martial Arts Dining arc of Ranma ˝. Before Ranma goes into the bathroom to train for a match, he tells Akane to not look inside. She doesn't, until she hears screams of pain. She runs in to find Ranma turned into a boy and in a feminine, iron corset too small for his male body. He yells at her to stop looking.
When Ranma loses the Dragon Whisker that stops his hair from growing rapidly, Akane runs after him. She finds him alone in a dark room and moves to get in closer, but Ranma shouts at her, "Don't look at me, Akane!"
Ryoshi from Ookami-san has a severe aversion to being stared at, and will yell these words whenever he becomes the center of attention. He gets better as the series progresses.
In Empowered, when Sistah Spooky is briefly depowered and returned to her mid-puberty appearance, she screams this as she traded her soul to become forever beautiful.
Secret Six: Horrifyingly done by Junior, due to the heavily implied sexual abuse she suffered at the hands of her father and a policy to kill anyone who does.
In Morbius #1 Michael says this while trying to hide his face when he is confronted by his ex-fiancée Martine.
Hellraiser: Frank tells this to Julia before stealing flesh from his victims.
Cole Sear in The Sixth Sense keeps telling people, "Don't look at me like that!"
Bram Stoker's Dracula has Mina walk in on Dracula ravishing a spell-ensnared Lucy. Since he's not exactly looking his best in any number of ways, he tells her "Do not see me!". It works due to his hypnotism powers, and Mina seems to have no memory of what she saw.
Said frequently in Blue Velvet. One of the film's most iconic lines is Frank Booth's "Don't you fucking look at me!". Thanks to an extremely disturbing case of Stockholm Syndrome, Dorothy has ended up enjoying abuse, and so uses the same line when the power positions are reversed with another character.
In one of the film versions of Wuthering Heights, Heathcliff (played by Tom Hardy) says this to his wife Isabella while they're having sex. He later mentions that because she shares eyes with her brother Edgar Linton, whom Heathcliff has hated for most of his life, he "can't look on them without wishing [her] harm". Much is made in both the book and film of how different Catherine Earnshaw's dark eyes are from the Lintons' blue ones.
In one of the many film versions of Oliver Twist, Bill Sykes (played by Tom Hardy) seems to hate people staring at him, but is rather inconsistent in it; several times he threatens people who do look at him, but other times he seems fine with it, and will hold a conversation with them and have no problem making eye contact. This is possibly a nod to the book, where Sykes' last words refer to "the eyes" of dead Nancy.
In The Elenium and The Tamuli series by David Eddings, the goddess Aphrael is normally in the form of a six year old child. She has several different forms, including her "real" form as an adult woman, which she never uses except when changing forms. She doesn't like anyone to see her changing forms.
In Discworld, Angua von Uberwald, a werewolf, has no problem with people seeing her as a human or as a wolf, but hates anyone seeing the actual change. It's hinted to be a Brown Note for canines and humans alike, since Gaspode was reduced to a whimpering mess the last time he didn't shut his eyes in time.
All werewolves seem to have this; Angua's Ax-Crazy brother Wolfgang will gladly walk around naked in his human form (claiming it's more natural), but he and all his fellow werewolves will avert their eyes from each other during the actual transformation.
In Kingdoms and Conquerors, T'zinkin refuses to look at Ryan, and begs him not to look at her, because she 'isn't worthy' when he explains for the thousandth time that he isn't a god, she replies that she isn't worthy- because she wasn't able to save the others.

Live Action TV
Angel: Angel says this when he sees his true demon form in Pylea.
Shouted word for word by Kramer on an episode of Seinfeld after a bout of chain-smoking ruins his appearance.
In the Scrubs episode "My Bad Too," Dr. Kelso says this to J.D. and Elliot when they find him eating a chocolate cake he had thrown away before out of the trash.
There is something of a blink-an-you'll-miss-it moment in the Buffy the Vampire Slayer episode "Fear Itself". When Buffy enters the Goat Room she comes across a lot of terrified party-goers. One of them is trying to hide his face: Oz, who had been turning into a werewolf moments before and doesn't yet realise he's changed back.
In the Doctor Who episode Daleks in Manhattan, Lazlo says this and tries to hide his face when his girlfriend finds him. Given that the poor guy has been turned into a humanoid pig, it's understandable that he's not happy.
Two-Faced injured veteran Richard Harrow of Boardwalk Empire doesn't much like being looked at with his mask on, but is mortified to be seen with it off. Gets an Ironic Echo in the season three finale when he doesn't want his girlfriend to look at the good side of his face, because it's splattered with blood.
Whilst utilising his "Dashing" gimmick, Cody Rhodes had his nose (legitimately) broken by Rey Mysterio's 619. Psychologically broken by the perceived "imperfections" in his face, and forced to wear a protective face mask, Rhodes' narcissist gimmick shifted to that of a deranged, self-loathing, paranoid AxCrazy. He took to wearing a hooded jacket on his way to the ring, shielding his face with his hands, and giving interviews/promos in diminished lighting. As his mania grew, Rhodes took to covering the faces of his felled opponents (and audience members) with paper bags, so discussed was it with the ugliness he saw around him and in himself.
When Kane's mask was forcibly removed in 2003, he under went an Heroic BSOD that led to a full-on Face-Heel Turn. He took to walking to the ring with a black towel draped over his head, and brutally attacked anyone he thought was mocking his appearance.
In Tales of Symphonia, Collette uses this phrase when her clothes are torn, revealing that her Cruxis crystal is taking over her body.
There is a rare comedic example in the poorly translated Pokémon Vietnamese Crystal. Your rival shouts angrily, "WHAT DON'T STARE ME ALWAYS" and kicks you when you talk to him at the beginning of the game.
Played for drama in Fallout: New Vegas by the Nightkin. Their nature as stealth experts who spent all their time shrouded by Stealth Boys makes them despise being stared at, and the trope phrase is their reaction to the player character even glancing in their general direction. The side effects of prolonged Stealth Boy use also all but guarantee they'll develop debilitating mental disorders such as schizophrenia (on top of being Super Mutants). In one case, you can even annoy one of them just by staring at him.
In Minecraft, looking directly at one of the Endermen (as in, moving the reticule in the center of the screen over them) causes them to freeze and turn to face you. The moment you look away, they attack, moving very fast and teleporting if necessary to close the distance. They also make a creepy growl/scream sound.
In Persona 4, this is what Chie says to the Protagonist and Yosuke when they see her confronting her Shadow self.
In Nier, Emil screams this after he discovers that fusing with his monstrous sister stabilized his powers and transformed him into a skeletal being similar to her. Without any hesitation, Nier hugs the sobbing Emil and does his best to comfort him.
Antichamber: Certain parts of the environment change or activate depending on whether or not you're actively observing them.
At the end of the Cocoon Academy arc in Brawl in the Family, when Pinky realizes that his exposure to Dark Matter turned him blue, he tells everyone in the room "Ugh, geez...don't look at me, you guys." Even as an adult as Metaknight, he is extremely paranoid about being seen without his mask.
Two-Face tries to hide his disfigurement when his girlfriend comes to see him, and gets mad when she removes the cloth covering half his face.
There was also the former starlet who covered her face with a mask at all times, at the risk of her Berserk Button. When she's unmasked at the end, Batgirl whispers that "She's beautiful," but Batman coolly replies that to the woman herself, all she can see are the flaws.
On Chowder, Gorgonzola said this once so that no one would look at his shame!
Gazpacho says this when he banned himself from his own stand.
Spoofed on Invader Zim by Chickenfoot, a man stuck in a chicken outfit who's convinced that he's a hideous abomination. During the retelling of his backstory to Dib, he screams "Don't look at me!" at random intervals.
