Sunglasses at Night



""These sunglasses sure make it hard to see in the dark, but I refuse to take them off because I'm an American and Americans always wear sunglasses!""

- Bandit Keith, Yu-Gi-Oh the Abridged Series

Sunglasses serve mainly four purposes:
 * 1) To block out the sun or very bright lights from one's vision.
 * 2) To look totally cool. Or, to look like you're trying to look totally cool.
 * 3) To cover up disturbing and/or missing eyes. (This is the reason why some blind people wear sunglasses In Real Life.)
 * 4) To hide where the gaze wanders when passing by. (Actually often combined with the #2 purpose. And most of them usually play poker.)
 * Also, to "keep track of visions in my eyes."

Then there are times where a character wears glasses most of if not all the time, even if it's impractical to do so. Sunglasses at Night is a trope where the glasses wearer is known for wearing their shades on even when it's nighttime, when they are fighting and in some occasions, when they are asleep. Most of these characters do it because of reason #2, but for others it is #3, or the whole thing is Hand Waved. Sometimes justified because the shades do something unusual. Other characters have enhanced senses, so they follow reason #1 even at night. Many of the characters wouldn't be as recognizable without them.

A subtrope of Cool Shades and Useless Accessory. Compare to Sinister Shades. Named for, but mostly unrelated to, a song by Corey Hart.

Anime

 * In Episode 11 of Neon Genesis Evangelion Gendo Ikari keeps his sunglasses on despite the fact that NERV is experiencing a station-wide blackout.
 * Bandit Keith of Yu-Gi-Oh! doesn't take his sunglasses off even when navigating a dark cave in the Duelist Kingdom saga, something that gets made fun of in Yu-Gi-Oh the Abridged Series.
 * Rei-kun of Kodomo no Omocha wears his sunglasses wherever he goes to show his devotion to Sana-chan, who picked him up off the street when he was homeless and made him her manager. She thinks it's cool, therefore that's what he wears.
 * Noriaki Kakyoin from JoJo's Bizarre Adventure: Stardust Crusaders starts wearing sunglasses 24/7 after  He still keeps them on during the final battle. Which happens naturally at night.
 * Kamina of Tengen Toppa Gurren Lagann wore his famous orange sunglasses all the time even though he spent most of his life underground with no knowledge of the sun's existence (which makes you wonder how he even got them in the first place). However, the color of those sunglasses may imply he's wearing to help him see in the dark.
 * Simon sports an epic, red pair later on even though.
 * Boota, too.
 * Scar of Fullmetal Alchemist wears them to conceal his red eyes, a sign of his Ishbalan heritage.
 * For the same reason, Major Miles up at Briggs. That, and preventing snow-blindness.
 * Shino Aburame of Naruto has never been without his sunglasses, nor has any other member of his clan.
 * This has lead to A popular fan theory that the bugs in his body have eaten out his eyes, serve as his eyes, or have augmented them in some way
 * Killer Bee is also always wearing sunglasses, even in his first appearance where he's coming out of a dark cave.
 * Harima from School Rumble is almost never without his shades.
 * Also, during the survival game (which takes place at night) Hanai shows up with a sunglasses, prompting several people to hang a lampshade on it. Granted, eye protection was required due to the nature of the game, but nobody said you can't just wear a visor.
 * 7th squad lieutenant Iba Tetsuzaemon and the Vaizard Aikawa Love from Bleach.
 * Black Lagoon. When Mr. Chang does it, it's Badass. When Lotton the Wizard does it...not so much.
 * Yamaki in Digimon Tamers only has his sunglasses off for about a minute of his total screentime, if that, and is often literally wearing them at night (or indoors in a darkened room). They also function as Sinister Shades, even though he retains them.
 * Satsuma (aka Samson) in Digimon Savers, on the other hand, is literally never seen not wearing his. He even drove at night still wearing them.
 * Despite being a nocturnal vampire, Alucard is prone to his trademark shades. When we first meet him he wears those orange sunglasses of his. He also wears them in that dark basement back at Hellsing Manor.
 * Although he's seen without them half the time, Mera from Tokyo Tribe 2 sometimes wears his sunglasses inside, outside, and at night. Sometimes he wears them so much, that his commander Buppa has to order him to take them off whenever inside.
 * Numata from Kurosagi Corpse Delivery Service. As it turns out, it's
 * Bear Walken and Bunji Kugashira of Gungrave both perpetually wear sunglasses. Bear's eyes are seen in the anime, Bunji's never are.
 * Mamoru from Until Death Do Us Part; justified in that he's blind and they allow him to kind of see (example here).
 * King Kai of Dragonball Z.
 * Master Roshi as well.
 * Nanba-san of Living Game appears without her sunglasses for only two or three panels out of 100-odd chapters.
 * Shizuo Heiwajima from Durarara!! evidently sees no reason to take off his sunglasses when the sun goes down or he's off the job. Given that they're implied to be a gift from Tom, he probably just clings to them like he does his other Memento MacGuffins.
 * Michiko in Michiko to Hatchin. On one occasion, she's not only driving her scooter at night while wearing sunglasses, it's also raining to boot!
 * Younger Togoro of Yu Yu Hakusho he only removes them when the fighting gets serious.
 * Quattro Bajeena (Char Aznable) from Mobile Suit Zeta Gundam wears his shades, even in space.
 * The three "Hunters" from "Elfen Lied" Bando, The Unknown Man, and The Agent.
 * In Black Butler, John Brown always, always keeps on his anachronistic aviator mirror shades, even at night in badly-lit places. It is unknown what his eyes really look like.

Comic Books

 * Cyclops of the X-Men wears ruby-quartz sunglasses when he's in his street clothes to keep his eye beams at bay.
 * Hex, from Tangent Comics, as part of his obsession with being, and being considered, cool.
 * For no real reason, The DCU's Kid Eternity never takes off his sunglasses.
 * Blade from Marvel Comics
 * The Corinthian of Neil Gaiman's The Sandman. Justified, in that he has tiny mouths with razor-sharp teeth where his eyes should be. We get several brief sequences from his POV in The Doll's House that include a blue tint to show this. In the second scene with him it becomes extra-clear that he's wearing sunglasses (rather than just standing in shadow) when a would-be mugger knocks them off and he has to put them back on a few panels later. Needless to say, you really shouldn't touch the shades.
 * The Anarchist of X-Force (later X-Statix) always wore his tinted sunglasses. Always. Even in a flashback to his childhood and when he was otherwise naked, like in the shower. It's implied that his eyes are overly sensitive to light, and that they're prescription.
 * Matt in Dramacon wears sunglasses for the third reason.
 * The vampiric Cassidy from Preacher (Comic Book) wears sunglasses 24/7 (except during flashbacks to his human life). Towards the end of the book, we find out why.
 * And before that, every time they come off the reaction is, "My god, what happened to your eyes?!?"
 * The titular character from Mr. X always wears sunglasses. Presumably to cover up the damage that years of drug-assisted sleep deprivation have done.
 * A different Mr. X, a Wolverine villain and former member of the Thunderbolts, also wears sunglasses all day, every day. He's first encountered by his new T-Bolts teammates at a ballet performance; Paladin took care to notify him that he looked like an asshole wearing sunglasses indoors at night.
 * The Phantom never shows his eyes in most adaptions. If he's not in costume and wearing his mask, or in shadow, he's wearing sunglasses.

Fanfic

 * Ghost from Yet again, with a little extra help wears these
 * In Naruto Veangance Revelaitons, the gray-haired man and the blonde-haired woman on the Council wear these at night, and it's lampshaded in the narration. There is a justification, though;.
 * In With Strings Attached, Ringo constantly wears his fake (solid obsidian) sunglasses to hide the fact that he's walking around with his eyes closed all the time. Mostly it's just an affectation, though. And he loses the glasses when they get turned into a living creature.

Film
"Elwood: It's 106 miles to Chicago, we got a full tank of gas, half a pack of cigarettes, it's dark... and we're wearing sunglasses. Jake: Hit it."
 * The Blues Brothers is practically the Trope Namer here.


 * Most films derived from H. G. Wells' The Invisible Man include sunglasses in the disguise.
 * Pretty much the entire cast of The Matrix wears their sunglasses at night, at fights, at eating ... at least while they're inside the virtual world. Real world, not so much. (Albeit mostly because you can't even see the sun in the real world, let alone find an intact pair of sunglasses.)
 * Riddick from Pitch Black wears not just sunglasses, but welding goggles, because his eyes have been altered to be super-sensitive to any light, as recounted in Escape from Butcher Bay. As a consequence, his eyeballs see things in just-next-to total darkness in high resolution, and anything overly bright burns them.
 * Vince in My Science Project wears sunglasses all the time. When asked why he is wearing them at night, he answers "Because when you're cool, the sun shines on you 24 hours a day."
 * The Terminator, full stop.
 * Well he is a robot after all, and can see pretty well regardless of whether he's wearing them or not. Rule #2 all the way.
 * Also, when the skin around the eyes is damaged, exposing the machine, #3.
 * The Men in Black also use their shades for a purpose: It keeps them from being affected by their memory-erasing Neuralizer.
 * Zaphod Beeblebrox from the The Hitchhiker's Guide to the Galaxy also doesn't take off his sunglasses in a cave because they are "peril-chromatic," that is, they turn black at the slightest hint of danger, thus preventing you from seeing anything that might alarm you.
 * One of the Feelies with the text adventure game was a set of peril-sensitive sunglasses..
 * In X-Men Origins: Wolverine, Sabretooth taunts a young Cyclops by telling him that it's a little too dark to be wearing sunglasses. Of course, Cyclops kind of needs to wear them.
 * Worn by the Men in Black soldiers in the cliche-ridden Mega Shark Versus Giant Octopus, even in poorly-lit laboratories and interrogation rooms.

Literature

 * Crowley from Good Omens. As Hastur comments, "He wears sunglasses even when he don't need to. Flash bastard." When they fall melt off at one point, he's revealed to have snake-like eyes.
 * Maciek from Ashes and Diamonds; his character in The Film of the Book is one of the iconic examples of this trope, arguably one of the Trope Codifiers. Unlike many later examples, he has an in-story reason for it: his eyesight was damaged fighting for La Résistance in the Warsaw Uprising.
 * Phil from Neil Labute's play The Shape of Things wears sunglasses on the top of his head constantly. His fiance, after having broken up with him, comments: "And Phil? You don't really need sunglasses at night."
 * The main protagonist of Ben Elton's 'Stark', one Colin 'CD' Dobson, is constantly wearing sunglasses, even at night and when taking shot at.
 * In the first Artemis Fowl book, Butler questions Artemis about why they have to wear sunglasses during their fairy kidnapping attempts at night.
 * In William Gibson's Sprawl stories, Molly Kolodny (aka Molly Millions, Sally Shears, etc.) in Neuromancer, Mona Lisa Overdrive, and the short story "Johnny Mnemonic" never takes her mirrorshades off. Because they're implanted into her face.
 * For that matter, Sublett in Gibson's book Virtual Light has mirrored contacts he wears all the time due to a light allergy.
 * In the Dale Brown novel Edge of Battle it is noted that "Comandante Veracruz" wears sunglasses almost all the time.
 * In Gaunt's Ghosts novels Ezrah ap Niht wears sunglasses given to him by Varl almost all the time, even indoors.
 * Joe Pike from the books of Robert Crais wears glasses all the time including literally at night. It was seven books before we found out his eye color. This is part of his extreme stoicism and when they do come off in L.A. Requiem it's symbolic.

Live Action TV
"Sam: "You gotta calm down." Dean: "Calm down? I'm wearing sunglasses at night. You know who does that? No talent douchebags.""
 * Hard Gay.
 * Clifford of The Muppets, except in Muppets Tonight. It seems likely that "classic" Clifford doesn't have eyes under the shades, so taking them off would be a bit Nightmare Fuel.
 * Fozzie also wore them one episode, after the band declared him officially hip. He spent the rest of the episode bumping into things from wearing them indoors.
 * Battlestar Galactica Reimagined. Romo Lampkin wears his sunglasses constantly, even in the dark corridors of Galactica. He is however a kleptomaniac lawyer who wouldn't want people to see where he's looking. Not to mention the times he finds it useful to remove them for effect (e.g. when he's interviewing Caprica Six).
 * Cameron did this, though as part of a Shout-Out to the T-800 of the above films.
 * The Doctor, briefly in season five's "The Hungry Earth". Justified in that they're night vision sunglasses.
 * The Man Show suggested doing this when walking on the street to ogle women without getting noticed.
 * CSI: Miami: Horatio Caine, though the main purpose seems less to avoid glare and more to put them on or take them off dramatically.
 * In the fifth season Supernatural episode Changing Channels, the main characters are trapped inside various television shows. This trope is lampshaded in a thinly veiled CSI: Miami parody:

Manhwa

 * Hom from Welcome to Room 305 never takes his sunglasses off. He wears them in bed as well.

Music

 * The aptly titled Corey Hart song "Sunglasses At Night".
 * The 69 Eyes song "Gothic Girl" says that the eponymous character "loves her sunglasses after dark".

Newspaper Comics

 * Peanuts - Snoopy, in his "Joe Cool" guise.
 * Candorville - Clyde even wears his in bed.
 * Uncle Duke in Doonesbury wears his all the time. His eyes would be pretty messed up if you saw them, for obvious reasons.

Video Games

 * Johnny Cage from Mortal Kombat, was always known for his $500 sunglasses, but starting with MK Trilogy, he stopped taking them off before a battle.
 * John Crawley and Mr. Big from Art of Fighting both go into battle with their sunglasses on. They would come off only when the opponent knocked them off their face.
 * In Mr. Big's King of Fighters appearances, the glasses stay intact throughout the battle, as with Clark and Choi. In KOF: '98, Clark actually puts his glasses on before the match.
 * Not only does the Duck King from Fatal Fury wears his glasses in battle and at night, but he changes to a new pair for each new costume he wears. Cheng Sinzan also sports shades in battle after his initial game appearance.
 * Captain Commando is always seen with sunglasses, always. He even transforms into superhero by putting on a pair of sunglasses over another pair.
 * Damnd/Thrasher from Final Fight.
 * Auron from Final Fantasy X fits in the classes 2 and 3
 * Lampshaded in Deus Ex by J.C Denton - "My vision is augmented."
 * This is after he's been called out on it by Agent Navarre - "Don't tell me you're going to wear those sunglasses during a night-time operation..."
 * Coincidentally, there's a very infamous "anti-walkthrough" (how to completely take apart the game in normal play) for Deus Ex called Sunglasses at Night.
 * Deus Ex Human Revolution continues the tradition, going so far as to have sunglasses one of Adam Jensen's augmentations. One possible NPC response is "Nice sunglasses, but it's night time, you dig?"
 * Wesker in Resident Evil series, but from Code Veronica onward, he has a reason. Perhaps the most ridiculous use is when . Granted labs do require some form of eye protection but it is still disconcerting when even before he injects his virus, he chooses to wear shades in a foggy nighttime forest and rather dark mansion.
 * In Resident Evil 5,.
 * Roy Koopa from Super Mario Bros. was actually named for his ever present sunglasses ("Roy" as in "Roy Orbison").
 * Eggman in the Sonic the Hedgehog game always wears those little blue glasses that hide his eyes for no apparent reasons. Even on dimly-lit space colonies. Maybe they're for protection, right? No, he sometimes covers them up with big black (welding?) goggles. Apparently, in the very visually-detailed 2006 title, Eggman's eyes can be seen behind his glasses, and they're blue.
 * The pair he wears on top of his head are basic safety goggles - apparently he builds his robots by hand sometimes - and in the 2006 game you can clearly see that the regular sunglasses serve as micro-computer screens for the Doctor.
 * Rude from Final Fantasy VII. In The Movie sequel, when his glasses are knocked off and cracked, he simply reaches into his jacket and pulls out another pair.
 * Blake Hall from Pokémon Ranger 2 wears them in the middle of the night...on the roof of a several-hundred-foot-tall building while standing close to the edge. Smart guy.
 * Played almost literally in Pokémon Gold and Silver, where you meet a man wearing sunglasses in the middle of Dark Cave (which requires using Flash to navigate through).
 * Mega Man: Proto Man has never removed his sunglasses/visor, in-game or out. The same applies to his Ruby-Spears and .EXE counterparts. (If one piece of art from 8 is to be believed, he even wears shades under his helmet's visor.)
 * Which is lampshaded by various webcomics like Bob and George all the time.
 * The Boy with Sunglasses from Mitadake High always wears them. Technically it's always night, but the lights inside the school are on unless someone cuts the power...
 * Johnny of the Guilty Gear series wears sunglasses even when he fights.
 * Heavy Rain: Norman Jayden wears his high-tech, crime scene analysing sunglasses indoors and at night.
 * Arthur Kilpatrick
 * Duke Nukem: the titular Duke.
 * Sam Burston, one of the punks of Mitsumete Knight, wears a pair of sunglasses at all times. The only time you can see him without them is when you beat him in a one-on-one duel: he'll be shown all battered and with his sunglasses broken.
 * Alpha Protocol's Mike Thorton can wear opt to wear sunglasses on any mission, at any time of the day. Most of them take place during the daytime, but a few happen at night, notably the airfield during Desert Shield, the infiltration of Marburg's villa in Deus Vult, and just about every mission in Moscow save the trainyard.
 * Fallout 3's sun glasses give your perception stat a bonus regardless of when they're worn, encouraging this trope. There is even a mod that gives the player a perk that causes all sun glasses to grant a massive charisma bonus, but only at night, with Rule of Cool serving as an in-game justification.
 * Guido Kandori from Persona 2. He has reasons.
 * The point-and-click adventure game Nightlong: Union City Conspiracy takes place entirely at night, and the protagonist Joshua Reev wears sunglasses the whole time. He takes them off at the end of the game, just as the sun is rising (though we don't get to see his eyes).
 * Sasha Nein of Psychonauts. This serves to cement his "cool secret agent" look and emphasize his emotional separation from everybody. Fandom has speculated that he's photosensitive.
 * Kazuhira Miller from Metal Gear Solid Peace Walker wears his aviator sunglasses every day, even during a thunderstorm. In addition, Miller wore them in Metal Gear 2: Solid Snake's rereleases, and in Metal Gear Solid (although that was actually Liquid Snake disguised as Miller).
 * In Metal Gear: Ghost Babel, Marionette Owl wore sunglasses even in places not appropriate (such as indoors during a blackout). It's justified in his case, however, as he was born with a mutant gene that allows him to see in the dark on par with an owl, and its hinted that his eyes as a result of the mutation shine in the dark, thus necessitating eyewear that masks the eyes.
 * Lampshaded in Paper Mario: The Thousand-Year Door with regards to underground koopas.
 * Boss, the bartender from Catherine wears them.
 * Night Trap has Tony playing this trope straight. At least one character puts a Lampshade Hanging on it by mentioning how strange it is that he wears Sunglasses at Night. Tony wears them to cover up the fact that his eyes glow green - which is something that vampires in this game have.
 * Team Fortress 2 - The Sniper always wears his piss-yellow colored tinted shades everywhere, the Engineer always wears welding goggles, the Pyro always wears a gas mask with tinted eye sockets, and other classes have hats that include sunglasses (including the infamous shuttered shades that are part of the so-called "Demopan" getup).

Web Comics

 * Shadehawk of Antihero for Hire. His Mission Control Gadgeteer Genius had to make him light-amplificating shades. He insisted, because they look cool.
 * Brent Sienna from PvP. When he gets a head injury in one story, the bandages get put on over his sunglasses. He finally takes them off, for one panel, at the altar when he married Jade. He puts them back on afterward, saying he hadn't seen unfiltered daylight in a decade.
 * Apparently they were perscription since he's recently started wearing regular glasses.
 * Riff from Sluggy Freelance never takes his off.
 * Slick from Sinfest never takes his off, even at the request of the girl he's pursued for the entire life of the comic.
 * He finally does take them off, but by then she had already stormed off when his back was turned.
 * As literal Men in Black, Agent Ben and Agent Jerry in The Inexplicable Adventures of Bob are never without their shades. This does have the regrettable effect of making them look like the Blues Brothers.
 * Othar Tryggvassen, Gentleman Adventurer! of Girl Genius.
 * He has taken them off on one occasion, though that story may not likely be canon.
 * That one may not be canon, but this one is.
 * Shilo from Rhapsodies
 * Rudy Dewclaw, Kevin and Kell. After being told of a night hunting competition in total darkness, Rudy's teammates all wonder why he is wearing sunglasses (To be fair, though, it's implied that even Rudy's teammates are unable to see anything).
 * Ian wears prescription sunglasses, albeit green-lensed ones. It sure makes finding the male toilets in a darkened cinema an interesting experience.
 * Johnny Danger of Legostar Galactica.
 * Axe Cop, as well as Flute Cop (and all his incarnations), Ralph Wrinkles, Wexter, and Telescope Gun Cop.
 * Kazu Ito in Mitadake Saga wears sunglasses (his alias is The Boy With Sunglasses) despite being trapped in a high school. Although it -is- night outside, it's sort of irrelevant.
 * In A Girl and Her Fed all those who have brain implants wear sunglasses all the time, since said implants make them very sensitive to light.
 * Dave Strider in Homestuck, as well as his brother, wears shades constantly.
 * Black Monday Blues of Dead Winter is almost never seen without his iconic red shades. In one moment his shades are knocked off and crushed but he simply reaches into his coat and takes out another pair.
 * But when it's really dark, he actually takes them off.
 * Paranatural has Mr. Spender, a teacher who wears sunglasses in class.
 * Komi from Darken is a Drow, so his eyes are very sensitive to light. But when asked why he doesn't take his shades off at night, he confesses they are prescription.
 * A variation in Air Force Blues: Barbie is revealed to have been wearing his aviator shades under his helmet visor. Thus, he manages to invoke this trope in broad daylight. It's a shame that he couldn't see that parked generator cart on the flightline.
 * Mia from Unintentionally Pretentious is blind but has relatively normal-looking eyes, and tends to wear sunglasses only when she's out and about by herself because she simply doesn't look blind enough without a cane or guide dog at hand.
 * Also possibly for protection.
 * Tom Mustaine from Soul Symphony wears shades all the time, even in school. It's mostly to make him feel more cool and intimidating.

Web Original

 * Partially invoked in the animated web saga Broken Saints, when the Shadow Men are shown wearing Cool Shades in a dark room, seemingly just so the artist could show the giant monitor they're watching reflected in the lenses. One of them, is shown wearing them for the
 * Lucy in Lonelygirl15 wears sunglasses even when it's dark and when she's fighting.
 * Cortez from The Leet World. During a challenge battle set at night, Ahmad asks the nearly-blind terrorist why he doesn't take his sunglasses off. His response? "I do not need my eyes to kill a man."
 * Fail Blog Sums it up nicely here.
 * The Necro Critic is a Caustic Critic who is characterized by his sunglasses.
 * When he read a viewer comment in his Sleepwalkers review, he put on a pair of reading glasses over his sunglasses.
 * The Mole in Happy Tree Friends. He's blind.

Western Animation

 * Alexander Cabot from Josie and the Pussy Cats was seldom seen without sunglasses.
 * Dale Gribble from King of the Hill practically wears his sunglasses as frequently as he wears his orange hat.
 * Numbah One from Codename: Kids Next Door.
 * In the first Futurama movie, Bender goes back in time to terminate Fry. When he puts on sunglasses before leaving, his reasoning is "It's really bright in the past."
 * The Batman: Worse-than-he-thinks-he-is Detective Cash Tank Anderson wears sunglasses at night. And speaks in third person. Detective Ying at one point starts hanging lampshades all over the place.
 * The Joker even nicknames the guy "Detective Shades".
 * The three main Dreadnoks in G.I. Joe are never seen without their sunglasses for no real reason.
 * Danny Dingo's biggest trademark in Blinky Bill are his sunglasses which he wears most of the time.
 * While monitoring the Autobots in Transformers Cybertron, Colonel Franklin and his goons wear sunglasses. At night. While looking through the tinted windows of their car.
 * In the first episode of X-Men: Evolution, Duncan invokes this trope by name on the aforementioned Cyclops.
 * Judy Funnie from Doug is rarely seen without her shades on. She does take them off sometimes, but not often.
 * Officer Barbrady in South Park.
 * Agent Six of Generator Rex, as part of his The Men in Black-esque outfit. They've come off maybe once or twice (and probably just the once) over the course of the entire series, and by the point where they do, it's far enough into the series that it's almost shocking to see him remove them, even though his eyes are perfectly fine underneath them.
 * Mr. Rotter and Enzo in Wheel Squad.
 * Chow in Jackie Chan Adventures. It's believed they're prescription glasses.

Real Life

 * Rapper P. Diddy.
 * Bono from U2, but his are prescription.
 * He once said in an interview that the glasses are partly because camera flashes hurt his eyes, partly for privacy and partly Rule of Cool.
 * Ray Charles's and Stevie Wonder's are both because some blind people have eyes that are disturbing to sighted people.
 * John Kay from Steppenwolf is legally blind. Bright light hurts his eyes/what's left of his vision, so they have a practical use.
 * Roy Orbison started as he didn't want to be seen wearing his glasses in public so he took to wearing prescription sunglasses all the time instead. He must have really hated contacts.
 * Rocky Sharpe of Rocky Sharpe and the Replays likes to begin his routine by taking off a pair of sunglasses, revealing another pair of sunglasses.
 * Canadian DJ Chris Sheppard. Let me put it this way - you actually have a better chance of catching Bono without his shades.
 * They say that if you wear sunglasses during a cloudy day that you're from Seattle.
 * Or just light-sensitive. A thin overcast can admit, and scatter, a surprising amount of light. What's worse, while overcast lowers the general light levels, thus forcing your eyes to dilate, it doesn't really stop much of the solar UV.
 * When amber sunglasses became commonplace for the second time in the 1980s, one aspect of their marketing was to suggest that they could be beneficial for night driving, as, rather than darkening the wearer's field of view, they worked by reducing glare and improving contrast, which might prove helpful when driving under the irregular lighting conditions of city lights. Amber lenses distort color far more than other kinds, which would be less noticeable and problematic under mostly-monochromatic nighttime conditions.
 * Also when driving in the winter, especially at night since the snow reflects the headlights.
 * Trope Namer Corey Hart wears his sunglasses at night, so he can, so he can, keep track of the visions in his eyes.
 * Actually, he started avoiding being seen wearing sunglasses under any conditions, because he wanted to be known for more than that one song (seemingly the only song of his anyone outside his native Canada knows).
 * Keiji Haino; there are few, if any, photos of him without the ubiquitous shades.
 * The former NFL quarterback Jim McMahon is never seen without sunglasses. Even during games he wore a tinted visor on his helmet—perhaps the first quarterback to do so—leading to the nickname "Darth Vader". His right eye is sensitive to light due a childhood accident when he tried to remove a rubber band from a toy gun with a fork.
 * Current Miami Dolphins head coach Tony Sparano also wears sunglasses all the time due to getting fryer grease splashed in his eyes while he was a cook suring his teens. It left him totally blind for a month.
 * Keiji Fujiwara has become somewhat infamous for being able to read his lines in the dark while wearing shades. Nevermind that he looks absolutely sharp.
 * Most albinos, due to their sensitivity to light and possibly disturbing eyes.
 * Another medical example is photophobia—which can, with sudden onset, mean you've got brain cancer, and is also a common result of aging. It can result in wearing sunglasses all the time, when symptoms are especially bad and people less than considerate about turning on lights. Personal experience has found that yowling and offering to pour acid in their eyes in thanks if they keep it up does, however, eventually get the idea that warnings are good...
 * Quite a few poker players take to wearing sunglasses so that other people can't see where they're looking, as that could be a tell at what they have. One of the more interesting pairs of sunglasses is Greg Raymer's "Monster Eye" shades, famously worn during his 2004 WSOP World Championship win.
 * While his aren't ubiquitous (the picture on his trope page shows him without them), Shinichiro Miki seems to wear them whenever he's around his Weiss Kreuz cast mates. This includes both inside during their interviews for the DVD extras and during their nighttime concerts.
 * Geddy Lee from Rush.
 * The late Mitch Hedberg.
 * Stan Lee wears sunglasses all the damn time. Why? Apparently, he saw it in a movie when he was younger and it looked cool.
 * Dwayne Johnson, better known as "The Rock", does this from time to time.
 * Filipino celebrity Randy Santiago wears shades all the time 'cause he has an eye defect.
 * During his 'Sane Man' show Bill Hicks taunts and impersonates an audience member wearing sunglasses, referring to him as "Mr. Cool Guy with the bloody shins", highlighting the man's vulnerability to low-lying furniture.
 * The United States Secret Service goes for the Sinister Shades look on purpose, to discourage anyone from messing with their "protectees". They also do it so they can stare at someone without being noticed, i.e. no one knows where they are looking.
