This is when a character makes some kind of error to do with their surroundings simply because they lack sight, either permanently or due to Temporary Blindness, or have misplaced their glasses. It can be anything from mistaking one object for another, one person for another, one location for another, or even whether something is there or not. For example, the character could pick up a bottle of vegetable oil instead of the intended bottle of water and drink it.
The character doesn't have to be completely blind, either — people who are extremely near- or farsighted, or whose vision is extremely blurry, can also do this.
This trope is used generally for comedic effect. Often greatly exaggerated, to the point of serious Fridge Logic.

- Sears Optical uses this several times with people who need glasses:
- A woman lets in a raccoon at the back door thinking it was her cat.
- A man accidentally snips off a lock of his wife's hair while trying to cut the tag off her dress. Additionally, it's implied that the wife also needing glasses is the reason she's with him in the first place, as she's noticeably more attractive than he is.
- A businesswoman in a hurry hops into a car and orders it to go to the airport. It's a cop car.
- There was a commercial for an optician's in Europe involving a woman inadvertently performing fellatio on the gearshift of a car instead of the man sitting next to it — while "parking" with her boyfriend.
- A whole range of advertisements for SpecSavers opticians in the UK, featuring, amongst others, a shepherd who shears his sheepdog, an elderly couple who get on a rollercoaster thinking it's a park bench, a volleyball player who spikes a seagull instead of a ball, a lifeguard who mistakes a seal for someone who needs rescuing, an overly enthusiastic aerobics instructor who shows up in an elderly bingo and Postman Pat crashing his van through fields and picking up a sack of vegetables instead of mail. All ending with the slogan "Should have gone to SpecSavers", which has rather successfully entered the vernacular.
- Ranma ˝:
- Mousse certainly looks better without his Opaque Nerd Glasses, but once he takes them off he ends up mistakenly glomping any person or object in front of him, thinking it's Shampoo. Among the more unusual items he has mistaken for a curvy 16 year-old girl with knee-length lavender hair: a giant panda, Shampoo's 1ft-tall grandmother, a bicycle, a 3ft-high tanuki statue, and a potted plant.
- At one point, while on a "date" with Akane, Ryōga (who has good eyesight) is frisked in the darkness of an ocean-themed haunted house by Shampoo. Elated by what he thought is a forward advance from Akane, he quickly turns around and hugs the first thing he found — a giant ocean sunfish model. He thinks Akane feels a little chunky, but he still doesn't open his eyes to realize his mistake.
- In Pandora Hearts, Break, who was completely blind at this point of the story, mistook Lily for Vincent and kicked her.
- A Tear Jerker variety happens in the backstory of Rurouni Kenshin.

- There was a Magoo-like character in the British anthology comic The Beezer called Colonel Blink (The Short-Sighted Gink). In another British anthology comic The Beano the character 'Erbert from The Bash Street Kids is also very Magoo-esque. Blinky in The Dandy (which took on several characters from The Beezer) is essentially a younger version of Colonel Blink. In what may be an attempt at political correctness strips in the late 90's and early 00's claimed that it wasn't Blinky's eyesight that was messed up, it was his head.
- A whole story from Cattivik revolved around his attempt to mug a blind guy with a really dangerous stick.

- Judge Dredd: The elderly Mrs. Gunderson, who's both near-blind and practically deaf, does this all the time, such as walking into a wall when she's looking for the door or pouring a drink on somebody's plate. She never even suspected that her former tenant "Jay De'ath" was an alien superfiend in hiding.
- Rompetechos (originally having his own comic-books, now a recurrent character in Mortadelo y Filemón) is a Mr. Magoo-like guy who crosses paths with Mortadelo and Filemón because of a mistake — Rompetechos may be looking for a priest and, seeing Mortadelo's black clothes, will harass him nonstop, meddling with Mortadelo's activities.
- Robin: When Tim went to ask questions of a temporarily blind Jason Bard the PI pulled his gun on the door and warned whoever had quietly entered his office that he knew they were there.

- In Adventures in Babysitting, Brenda, stranded in a bus station without her glasses, pets a huge rat thinking it's a lost cat.
- In Anchorman 2: The Legend Continues, Ron Burgundy goes blind and does things like biting into an ashtray thinking it's a waffle, setting his dishwasher on fire thinking it's a fireplace, brushing his teeth with a live lobster and drinking a bottle of ketchup thinking it's wine, even though he shouldn't need his vision to know if something's up. This was even lampshaded by Brian:
Brian: If you drank a bottle of that, that's like...that's like...like nine or ten gulps. Couldn't you tell that was ketchup?Ron: Did I stutter? I'm BLIND
- The main character in Blind Fury can defeat ninjas and gun-toting mooks with a sword despite being totally blind, but has trouble with everyday life.

- In the Daredevil movie, Matt asks Foggy for honey to put in his drink, and Foggy (deliberately) hands him mustard instead. Matt's other senses work just fine, however, so he switches drinks with Foggy without drinking.
- One comic setpiece in W.C. Fields vehicle It's a Gift involves Mr. Muckle, who is both blind and half-deaf, visiting poor Harold Bissonette's grocery store.

- Pew from Muppet Treasure Island is constantly bumping into things, except on the few occasions when his enhanced hearing briefly makes him super-competent. He also believes Jim to be a girl.
- In Neil Simon's Murder by Death, the blind butler Jamesir Bensonmum is always doing things like that — eg, sticking stamps to letters but missing by a mile and sticking them to the table; or lighting a fire in a guest's bedroom... in the center of the bed itself. ("At least the bed will be warm," quips the guest.)
- A rare not Played for Laughs example in the Film Noir, On Dangerous Ground. Mary (who's blind) thinks her brother, who has killed a young girl, has returned home, but it's actually the cop that's been chasing him who enters.
- Robin Hood: Men in Tights has an entire character, Blinkin, who exists to act out this trope (see the page pic). Ironically, Blinkin is so surprisingly competent and skilled that his blindness is the only thing keeping him from liberating England by himself. He catches an arrow in mid-flight before it hits Robin Hood, saying he could hear it coming a mile away... and then asks who's talking when Robin congratulates him.
- In A Song Is Born, Frisbee walks into Honey's bungalow at the motel they stay at by mistake, believing it to be Prof. Oddley's, and since it is dark, he fails to realize his mistake and pours out the depths of his ardor to Honey, causing her to realize just how much he really loves her.

- A rare justified example occurs on Arrested Development with Maggie Lizer. She's not actually blind and is doing a really bad imitation.
- One Chappelle's Show sketch was about a Blind Black Guy named Clayton Bigsby. The mistake? He doesn't know he's black, and he's a prominent white supremacist writer and KKK leader.
- Mostly avoided/subverted on Covert Affairs with Auggie's character, although he did accidentally bad-mouth Jai's father as Jai approached, despite Annie's warning.
Auggie: I'm assuming from the silence and the stiletto in my shin that Jai has joined us. ...I'm off to do...anything else. (leaves)
- Doctor Who: "Extremis" has an unusual example — The Doctor, who was blinded in the previous episode, is preparing to read a Tome of Eldritch Lore. To do so, he uses a fancy gadget that temporarily restores his eyesight by borrowing health from his future self. When it does so, his eyesight is initially extremely blurry, and thus he mistakes an approaching Prophet of Truth (the villain) for Cardinal Angelo (who the Prophets had vanished earlier) due to its red robes.
- There was a case on Drake & Josh where Helen had eye surgery and had patches over both eyes for a while. After claiming she didn't need help, she picked up a baby carrier (yes, with a baby in it) and walked away, thinking it was her purse.
- Merc's wife in Episodes has a couple. In a funeral episode, Merc has a minder tasked with the sole job of "making sure she doesn't fall in the hole."

- A Running Gag with Private Vanderbilt, the fort lookout on F Troop. He once allowed two Indians wearing feather head-dresses to enter the fort unchallenged, and later explained "I thought they were turkeys."
- Sophia from The Golden Girls is prone to this whenever she loses her glasses. For instance, in one episode she tried to call her daughter to pick her up at a shopping mall after she lost her glasses but failed to manage it because she didn't realize that the machine she was using was not a pay phone, but a condom vendor instead.
- This is the entire point of the character Eli from Last of the Summer Wine.
- Crosses the Line Twice in a sketch in the Swedish sketch show Lorry: a blind couple buys a television set from a blind salesman, who then sends a blind errand-boy on a motorcycle to drive it home to them. Every one of them trashes everything around them, remaining cheerful and blissfully unaware all the time.
- Half the humour relating to The Mighty Boosh's Lester Corncrake derives from this. The other half is from him doing various things which imply that he can see.
- Happens several times in the Monk episode, "Mr. Monk Can't See a Thing".
- On one episode of The Nanny, Fran dates a blind man (played by Jason Alexander) to prove that she has more to offer than merely her looks.

- On The Odd Couple, Felix returns from the hospital wearing a post-op bandage (blindfold) as the result of a sinus procedure. Wanting to freshen the air in the apartment, he mistakenly grabs a can of whipped cream sitting next to the can of Glade. He also goes to the closet and mistakenly puts on his ex-wife Gloria's coat. After Oscar clues him in, Felix says "It fits!".
- Mr. Lomax in Psychoville is constantly making these sorts of errors, like mistaking a Club biscuit bar for a mobile phone (nobody ever rings him on it).
- This happens in one episode of Reba, during which Reba tries to take care of herself on her own after having an eye surgery (with hilariously disastrous results, such as drinking water out of a potted plant). Efforts made by Barbra Jean to assist Reba while the latter fumbles around without knowing someone else is nearby trying to help only amplify the hilarity further.
- A serious example is found in an episode of JAG, where a senior fighter pilot misjudged the height and distance to a Ridge, causing his wingman to clip a telephone pole with his F-14 Tomcat, lose control and eject. The plane crashes into oncoming traffic, killing a mother and child.
- Polyphemus from The Odyssey accidentally allows Odysseus and his men to escape after being blinded.
- Played for Drama in King Lear with Gloucester (whose eyes have been gouged out) and his son, who pretends to be "Mad Tom".
- Act II, Scene II of The Merchant of Venice. Launcelot's blind father, Old Gobbo, shows up and doesn't recognize him. Launcelot is a troublemaker, so instead of revealing his identity, he gets into a whole conversation with his father about "young Master Launcelot", finally revealing that Launcelot is "deceased". The trouble is, once he decides that the joke's gotten a bit old, he has trouble explaining to his father that he's really Launcelot, and not dead at all. The whole thing cumulates with Old Gobbo joyfully embracing Launcelot, complimenting him on his fine new beard — actually just his long hair, which his father has accidentally grabbed hold of. And that's only what's directly mentioned in the script. Depending on the performance, there will usually be plenty of visual gags involving Old Gobbo walking off in the wrong direction, bumping into the other characters, falling off the stage and into the audience, etc.
- In Katawa Shoujo, the legally-blind Kenji mistakenly buys a bunch of tubes of lip balm because he thought they were single AA batteries.
- In Homestuck, the now-blind Sollux is shown to be vacillating between Matesprit and Kismesis for Gamzee, but since he's looking at Lil Cal the puppet, it confuses the hell out of Karkat. Much, much later revelations about what exactly Lil' Cal is imply that he might have sensed part of Gamzee's soul in the puppet.
- Terezi has been the butt of this joke, although she can usually get around her handicap. Notably, when she adds sunglasses to pictures of Dave, she always misses his eyes. Also, in the Act 5 finale, she points in the wrong direction when everybody's staring into the sky and is gently corrected by Karkat.
- It's also pretty common for Terezi cosplayers to intentionally face the wrong direction in photoshoots, and for her to be drawn facing the wrong way in fanart.
- Mia from Unintentionally Pretentious is blind, and is occasionally prone to this.
- This trope is essentially the entire premise behind the Brandon Rogers "Fashion is Blind" sketch, which narrates the life and antics of Jurgen, a blind German fashion designer who also happens to be a chronic Cloudcuckoolander.
- In Suburban Knights, Todd in the Shadows winds up doing this thanks to his Dread Pirate Roberts costume's mask covering his eyes, including attacking Film Brain thinking he was one of the Cloaks and fighting an inanimate pole before falling over due to being disoriented. In the second instance Film Brain and one of the Cloaks actually stop their fighting to stare.
- In Eric Jacobuss's Blindsided, Walter finishes baking his pie and pours himself a glass of thoroughly spoiled milk before taking a sip and spraying said milk all over his new pie, ruining it (followed by attempting to wash his mouth out with the Tabasco in the fridge, and failing to get the glass right-side-up to get water to quench the hot sauce...), necessitating the convenience store trip that kicks off the plot. Why he didn't notice the smell...
- One episode of 2 Stupid Dogs is based on this. The dogs act as guide dogs for the blind man while he wanders around a construction site.
- Avatar: The Last Airbender:
- Toph falls into the water, and can't swim. Sokka (a guy) yells that he'll save her, but Suki (a girl) jumps in before he can do anything. Toph kisses "Sokka" not realizing it's really Suki. (Yes, the Tokka shippers love that one.)
- In another episode, declaring that she doesn't need the help of someone with sight to help put up posters, she glues the wrong side of the poster to a wall. "It's upside-down, isn't it?"
- Also occasionally inverted:
[the Gaang are about to tunnel underground to try and undermine the giant Fire Nation drill machine]
Sokka: Aah! It's so dark! I can't see a thing!
Toph: Oh no, what a nightmare!
- And played with/invoked:
Sokka: Toph, when I was in town I found something you're not going to like [unfurls a wanted poster]
Toph: Well it sounds like a sheet of paper. But I guess you're referring to what's on the sheet of paper.
- Toph gets this a lot, both ways. She's the world's most powerful Earthbender, who can tell where things are through the vibrations in the ground, to the point of knowing exactly who's who by their movements, and even being a Living Lie Detector because the same changes in heart rate and breathing when you lie are transmitted through the ground to her some distance away. It's easy for the others to forget she's blind when she's been walking with them and nearly every bit as aware of what's going on as they are. So three different characters forget, at different times in the same episode, that she can't read, and things like that happen now and again. Meanwhile, as powerful as she is and as good as her powers are at helping her navigate, she's still blind. That can mean things from walking into Sokka when he stops suddenly (in sand, her range and accuracy drop) or dangerous things like not knowing where airborne enemies are.
- On Chowder, a Magoo-like character crashes into Mung Daal's kitchen, mistaking it for his home, and tries to make out with Schnitzel, whom he mistakes for his wife.
- In the first episode of Eek! The Cat entitled "MiserEek", a blind old lady adopts the titular Eek and thinks he was her cat, Mittens. Because of her blindness, the old lady did a lot of wrong things to Eek, such as showing him a big vacuum cleaner by mistake (cue a scared scream from Eek), accidentally putting him into a pot of boiling water (instead of a chicken) and scrubbing butter on him.
- Leela is medically required to wear an eyepatch after an accident with a spice weasel. She has only one eye. And she's the pilot of the Planet Express ship. Fry tries to make her think she's still piloting the ship when it comes under attack by putting Nibbler's food bowl in her hands, and he manages to competently keep them intact. Then she realizes she's holding the bowl and retakes the wheel. She then gets the fuel line blown and they're taken captive.
- Professor Farnsworth is generally implied to be blind without his glasses. Since they're thick enough to stop gamma rays, he's more or less blind with them. He switches to reading glasses once where each lens is a cylinder a foot long. They punch through the magazine he's trying to read.
Farnsworth: Why, Zoidberg, there's a lovely picture of you in here!
- In the Mickey Mouse (2013) short "Coned!", Mickey attempts to make his dog Pluto feel better about his Elizabethan collar by wearing one as well until it is time for Pluto's to get removed. Because Mickey insists on wearing the cone even when it impairs his vision, it leads to him obliviously injuring himself and causing destruction everywhere he goes.
- Anything featuring Mr. Magoo is based around this. He's an old man who is very much Blind Without 'Em, except he doesn't have 'em and refuses to get 'em, stubbornly insisting that his eyesight is perfect and everyone else doesn't know what they're talking about.
- This was done a few times with Velma after she lost her glasses on the CBS Scooby-Doo series. Among other things, Velma once approached a statue and thought it was Shaggy, petrified with fear.
- The Simpsons:
- Bleeding Gums Murphy learned to play sax at the feet of Blind Willie Witherspoon:
Willie: I've been playing jazz for 30 years and I just can't make a go of it. I want you to have my saxophone.
Bleeding Gums: This isn't a saxophone, it's an umbrella!
Willie: So I've been playing a umbrella for 30 years? Why didn't anybody tell me?
Bleeding Gums: Heh, we all thought it was funny.
Willie: That's not funny.
- Milhouse frequently gets the Blind Without 'Em treatment when he loses his specs, or if someone just takes them. In "Summer of 4 Ft. 2", Bart Takes them to spy on Lisa and doesn't bother to give them back. A horshoe crab then crawls into frame and Milhouse pets it, mistaking it for a lost puppy.
- When Bart becomes a faith healer he "heals" Milhouse by throwing away his glasses. Milhouse belives it, then walks into traffic and gets hit by a car.
- In one episode Homer's vision is distorted when he starts wearing a pair of glasses he found in the bathroom at work.
Lisa: Dad, you shouldn't wear glasses that weren't prescribed for you.
Homer: [to Bart] Lisa, just because you're ten feet tall doesn't mean you can tell me what to do.
- Bleeding Gums Murphy learned to play sax at the feet of Blind Willie Witherspoon:
- Star Wars Rebels: "Through Imperial Eyes" has a serious variant — Kanan gets himself stunned because he doesn't know that the Imperial officer he tries to mindtrick is Governor Pryce, who's too strong-willed for it to work. And not only does Kanan not know who Pryce is, neither does Rex, so he can't warn him.
- In 2003, at Lake Calhoun in Minneapolis, a 7-year-old blind girl drowned because all three counselors were also blind.
- One of Barack Obama's senior staffers mistook the second-most senior Army general for a waiter at an event because he was standing in her periphery, she wasn't wearing her glasses and all she could see were the stripes on his pants. The general laughed it off, while she was mortified.
