Things are not as they seem. What you see is not what's truly there. It may be a building rendered {{Invisible}}, or a person who has [[VoluntaryShapeshifting taken the guise of another]]. It may be InvisibleToNormals, hidden by thermoptic camouflage, holographics, a PerceptionFilter, a {{Glamour}}, or even some kind of implausibly specific hallucinogen.

Whatever the case, to see to the heart of the matter, you need the TrueSight. This trait cuts through illusions to show objective, absolute truth, rendering all of that stuff above useless. Of course, it may well come at a price, either on a per use basis something or more permanent, such as the loss of your [[BlindSeer earthly vision]]. On the other hand, it may just be hereditary, or a natural ability of your particular race, in which case, lucky you. Or it could be an ability bequeathed by some special object.

If possible, try not to overuse it, because it might be hard [[GoMadFromTheRevelation on your sanity]].

While TrueSight always involves true perception, it doesn't always give the user the ability to properly interpret what they see. Thus, they may see the truth and still come to an incorrect conclusion, and there may be reliable ways of fooling them.

Often a function of the MagicalEye. Not to be confused with precognition, the domain of {{Seers}}, or [[PsychicPowers clairvoyance]], usually the viewing of distant places. Often bundled with SupernaturalSensitivity and/or AuraVision. Supertrope of SeeThruSpecs, glasses or other lenses that have this ability, and SeeTheInvisible, which affects only {{Invisibility}}. Contrast GlamourFailure, when the illusion has some flaw that can be perceived by normal sight.

[[folder: Anime and Manga ]]

* TheHunter Quent Yaden from ''WolfsRain'' can see through the wolves' humanoid illusions when drunk.
* ''Anime/ElHazardTheMagnificentWorld'' has Nanami, who has the ability to see through illusion. She alerts the group to a Shadow Tribe assassin (who was in human guise) at Arlaman and, later, proves pivotal during Makoto's showdown with Galus atop the Eye of God.
** The problem is that she simply can't see the illusions themselves, so most of the time she [[IThoughtEveryoneCouldDoThat assumes everyone sees the same things as her]].
* The "Rabbit of Truth" from ''Manga/TheVoynichHotel'' grants this to the wearer.

[[folder: Film ]]

* The [[SeeThruSpecs sunglasses]] in ''Film/TheyLive'' reveal that certain people are really aliens, as well as the presence of subliminal messages.
* ''[[Film/{{Hellboy}} Hellboy II: The Golden Army]]:'' Krauss provides the BPRD with special goggles capable of seeing through magical glamour; the BPRD uses them to find trolls disguised as humans. As a ContinuityNod to the first film, when Hellboy himself is seen through these goggles, he's shown with longer horns and a fiery crown--accoutrements of the Prince Of Hell role that Hellboy has been rebelling against.
* Buckaroo Banzai from ''Film/TheAdventuresOfBuckarooBanzaiAcrossThe8thDimension'' receives the ability to see through the Lectroids' human disguises from the Black Lectroids. This proves to be bad news for the Red Lectroids.
-->'''Buckaroo:''' There they are.\\
'''Perfect Tommy:''' There who are?\\
'''Buckaroo:''' Don't you see them?\\
'''Sydney:''' See who?\\
'''Buckaroo:''' There! Evil ''pure and simple'' by way of the Eighth Dimension!

[[folder: Literature ]]

* Witches and Wizards on the Literature/{{Discworld}} have not second sight, but First Sight, and can see what's really there rather than what they expect to be there. This is partly because of magic and partly because they have no WeirdnessCensor.
* Wizards in ''TheDresdenFiles'' can use their Sight at will, with the caveat that anything they see, however wonderful or horrible, can never be forgotten, ever. It remains in their mind's eye, as fresh as if just seen, for the rest of their lives. When Harry catches a glimpse of an ancient horror, he has to ''rearrange the way he thinks'' just to make the seizures stop, and even then it's a good while before he stops shuddering.
** Also, in some novels, Harry creates an ointment to see through the Sidhe's glamour, which acts like a lesser version of TrueSight, with the advantage that non-magic users can benefit from it as well.
* In ''Literature/HarryPotter'', 'Mad-Eye' Moody's false eye can see through solid objects, clothes and incidentally, invisibility cloaks.
* Creator/StephenKing's ''The 10 o'clock People'' - Having quit smoking, and then taking it up again allows you to see the hideous alien forms of the powerful beings that have taken over the human race. They're called Batmen.
* [[DeanKoontz Dean R. Koontz]]'s novel ''Twilight Eyes''. Only people with special purple eyes can see the creatures known as Goblins as they really are. It's later revealed that this manifests in different way including True Smell.
* In ''PercyJacksonAndTheOlympians'' certain human characters where able to see through the mist. Rachel Elizabeth Dare uses this ability to guide Percy and Co through the Labyrinth.
* Luis from ''Valiant'' and ''Ironside'' in the ModernTalesOfFaerie trilogy can see through glamour and is impervious to enchantments. It's described as "TrueSight".
* "The Sight" is a form of magic in the Literature/TortallUniverse, which allows the gifted person to detect things such as magic, lies, illness, pregnancy, and godhood. There's also Kel's griffin feather headband, which allows her to see through illusions when worn above her eyes.
* Inverted in ''TheSwordOfTruth'': Jennsen (and any of the 'pristinely ungifted') can see the real thing underneath the illusion because she's [[AntiMagic unable to see or be affected by magic at all,]] rather than having some magical ability that allows her to break an illusion like many of the other examples.
* "Witch Sight" in the Literature/{{Chrestomanci}} series is able to detect spells and see through illusions.
* Way back in ''JourneyToTheWest'', this was one of Sun Wukong's [[GodModeSue many, many powers]].
* In AndreNorton's ''Literature/WitchWorld'' novel ''The Year of the Unicorn'', Gillian uses moly to give herself this and correctly name a Were-Rider.
* In Creator/RuthFrancesLong's ''Literature/TheTreacheryOfBeautifulThings'', Jack's illusions only temporarily work on Jenny. Jack warns her that the Fairy Queen will therefore be interested in her.
* Zoey's Seer Stone from ''Literature/TheHouseOfNight''.
* In Creator/SergeyLukyanenko's ''Literature/TheBoyAndTheDarkness'', after Danny lets a [[HumanoidAbomination Flying]] go, the other Wingers punish him by [[EyeScream cutting out his eyes]]. The Sunny Kitten restores his eyesight with the True Light. As a side effect, Danny's new eyesight is this trope. He is able to see through low-density objects (e.g. wood but not stone or metal) and becomes a LivingLieDetector. The Kitten warns Danny, though, that his new True Sight can cause him to see only the dark in people and develop a HolierThanThou attitude towards the others.
* In the novel of ''Franchise/SentouYouseiYukikaze'', Yukikaze has a specialized sensor suite dubbed "Frozen Eye" that is far more sophisticated than any other plane in the Faery Air Force. This also turns out to be the only thing that can detect [[spoiler: miniature JAM teleportation portals]]. In the first novel, it's unclear what is being detected because it only shows up as a solid straight line on the cockpit computer screen, but in the second novel, it is revealed that what Frozen Eye is actually detecting is [[spoiler: a series of tiny vibrations in the air that outline the opening of a portal]], which is invisible to both the naked eye and regular radar.

[[folder: Live Action TV ]]

* On ''{{Grimm}}'' the titular Grimms have the ability to see wesen (creatures revealed to be the basis of all fairytales) when the wesen lose control over their ability to hide their true forms.
** Any human can see a Wesen's true form, but that requires the Wesen to actively go "full [[GratuitousGerman woge]]", which requires even more effort than maintaining their human disguise. As one episode reveals, repeatedly going "full woge" can result in the Wesen being unable to maintain his or her human appearance for long.
* Eaglebones Falconhawk from ''Series/TheAquabatsSuperShow'' is given Eagle Vision to see his AttackAnimal The Dude. "And yes, Ricky, I ''can'' see fairies."
* In ''Series/{{Supernatural}}'', angels are naturally able to see the demons' true faces (which are apparently rather monstrous) instead of the face of the person that the demon is possessing.

[[/folder]]

[[folder: Mythology ]]

* [[TheFairFolk Fairy tales]] frequently include a means for mortals to see the fair folk and/or see through their {{Glamour}}. Common mechanisms are a special ointment to be applied to the eyes, [[TheMirrorShowsYourTrueSelf looking in a mirror]], and looking through a stone with a natural hole in it. Having [[InTheBlood fairy ancestors]] also usually helps.
* One such ointment appears in a Slavic tale where a bandit hero was invited to the local lord's palace to make peace. His best friend accompanies him and, suspicious of the lord's men and their strange behavior, sneaks some of their ointment and applies it to one eye. Upon closing the other eye, he sees that the palace is really a ruin, the other guests are withered trees, the lord's men are hounds, and the lord is {{Satan}} himself.

[[folder: Tabletop Games ]]

* ''DungeonsAndDragons'' has spells such as True Seeing and See Invisibility which allow the caster to see through various magical illusions.
** [[http://www.d20srd.org/srd/spells/trueSeeing.htm True Seeing]] also has the bonus of seeing secret doors and shapeshifted things.
* ''MutantsAndMasterminds'' includes True Sight as one of its stock SuperSenses powers, allowing the user to see through all illusions, all concealment, and see that which is hidden.
* In ''Tabletopgames/{{Shadowrun}}'', magicians can use Astral Perceiving to see a person's true aura.

[[/folder]]

[[folder: Video Games ]]

* A major strategy element in ''Videogame/StarCraft'' is the use of optical camouflage, concealment, and cover to be unseen by the enemy. As such, there are several units and building types that have "Detector" status, meaning they are able to thwart such tricks. The same aspect is used in '' VideoGame/{{Warcraft}} 3''.
** DawnOfWar has a similar feature for "infiltrating" units.
** LeagueOfLegends has invisible wards, traps and champions which can only be revealed by [[ExactlyWhatItSaysOnTheTin True Sight]]. This can be provided by certain wards, trinkets, defensive towers and (until the Season 4 updates) Oracle's Elixir would give the champion using it a true sight radius.
* ''Videogame/{{Egoboo}}'' has this as a spell.
* The Eye of Truth in ''Videogame/{{La-Mulana}}'' allows you to see InvisibleMonsters.
* The [[SeeThruSpecs Lens of Truth]] in ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' let you see invisible objects and creatures, see through walls that were normally opaque but weren't really there, and also see the contents of chests without opening them (thus avoiding booby traps, and wasting money, ammo, etc. when you can't carry anymore.) It returns in ''MajorasMask,'' and though simply named 'magnifying glass,' the same ''idea'' exists as far back as ''LinksAwakening.''
* Several characters (mostly those with great spiritual power) are able to see Amaterasu's true form in ''VideoGame/{{Okami}}''.
* The Reveal Psynergy in ''Videogame/GoldenSun'', which allows one to see through illusions and invisibility.
* [[VideoGame/DarkForcesSaga Jedi Knight]] has Force Sight that reveals invisible enemies.
* In GuildWars during the Ascension in the Crystal Desert the player wants to achieve this. However this is for storytelling only, since the player doesn't gain any special ability and is meant to cut through the invisibility of the ''Unseen Gods'' ([[spoiler: The Mursaat, powerful mages]]). So a player who skips the middle part will still be able to see and fight the ''Unseen Gods'' properly.

[[folder: Webcomics ]]


* In ''{{Webcomic/Roommates}}'' supernatural beings may or may not see through eachother's illusions depending on specialties, experience and power level, but the only mortal known to possess true sight is InspectorJavert... he is also low key AntiMagic. It might be a supernatural ability, or he might be just too stubborn and cynical for this crap.
** Likely has something to do with his [[Literature/LesMiserables Romani ancestry]] (to phrase it less politically correctly, he's at least half-Gypsy) and/or his comic-only relation to Morgan le Fay.

[[/folder]]

[[folder: Web Original ]]


* ''Website/ChatoyantCollege'': In Book 1 we find out that [[spoiler: Dawn]] has the gift of true sight. Later, we find out this is because [[spoiler: Dawn's Aunt Pru was given a special ointment by a faerie man]].

[[/folder]]

[[folder: Western Animation ]]

* ''RoswellConspiracies'': The main character, Nick Logan, is capable of perceiving the true appearance of camouflaged aliens, whether they are shapeshifters (Lycanthropes), using holograms (Vampires) or installed inside a human host (like the Vodun).
* In ''WesternAnimation/ThunderCats'' and ''WesternAnimation/ThunderCats2011'' this is one of the powers granted to the holder of the Sword of Omens as part of "Sight Beyond Sight" (also includes precognition and the ability to see great distances).
