"Can't see anything!... Sun... in eyes!... Must... talk like... this!"In works of fiction, heroes and villains alike will find every advantage to winning a battle, whether it's a personal Duel to the Death or the ultimate Final Battle. One of the simplest and most prevalent is based on a notion that if the enemy can't see you (or anything), they can't hit you: shining a super bright light source directly into the face of your enemies. This will work to varying degrees depending on the work, from completely blinding and incapacitating your foe to causing just a momentary inconvenience. Depending on the work, the light source could be any number of things. For example, in Fantasy works it's likely some sort of magic had a hand in it, while in Science Fiction it is more likely to find flashbang grenades or devices specifically designed for this sort of thing. The sun and its reflections are also widely used. A popular sword-fighting variant involves tilting a blade so it reflects the sun's light into your opponent's eyes. If some characters have been in the dark for a while, this can occur with much weaker lights than normal, while leaving other characters unaffected, since Day Hurts Dark-Adjusted Eyes. An example of Truth in Television, since the use of flashbang grenades is highly prevalent in modern police forces and armies have been using natural light in various ways to blind and hinder their enemies for centuriesnote . Compare: A Handful for an Eye, Step into the Blinding Fight, Tap on the Head, Deer in the Headlights, Inescapable Net, Stun Guns, Weakened by the Light, Instant Sedation, and Sub-Trope Blinding Camera Flash. Has nothing to do with the battle theme for Final Fantasy XIII. Not to be confused with the 1976 Bruce Springsteen/Manfred Mann's Earth Band song.

- Star Wars Legends:
- X-Wing Series: In The Phantom Affair, a gang of pro-Imperial thugs attacks Rogue Squadron pilot Tycho Celchu. He beats most of them down by himself, but the last one gets the drop on him and is preparing to deliver the final (possibly fatal) blow, when he's slashed through the eyes by a phantom Jedi's lightsaber, causing instant blindness and much pained yelling. It turns out later that the "Jedi" is just a hologram, and given that holograms are actually just light (lasers, to be specific), this trope stands.

- The Transformers: The Movie: Hot Rod shines his headlights into Galvatron's optics during their battle (in a dark room), and Galvatron's flinch gives Hot Rod a couple free shots at him.
Films — Live-Action
- Averted in And Starring Pancho Villa as Himself, in which General Pancho Villa has made a deal with Hollywood allowing them to film his battles. When attacking the fortress at Torreon, Villa originally intends to attack with the sun behind his troops, so the Federal defenders will be firing into the rising sun. But the primitive cameras of the day need more light, so his troops charge towards the sun and get massacred by the Federals who can see them clearly.
- In Batman Begins, Henri Ducard shows Bruce Wayne how to use a pinch of gunpowder to achieve this effect.
- The aliens in Battleship have a really low tolerance for light. A random crewmember figures it out by studying the eyes of a captive alien and pointing out that they look similar to his pet lizard's, who never likes bright lights. This is used to destroy an alien ship, when Alex and Nagata break open the window on its bridge with high-power sniper rifles. The aliens on the bridge are blinded by the rising sun for a few seconds, until their nictitating membrane closes to filter out the light. Enough time for the USS John Paul Jones to deliver a deadly barrage at point-blank range (for a warship).
- In Dark Wolf, two people manage to escape the werewolf by blinding it with camera flashes.
- Enemy at the Gates has Vasili pinned down behind a piece of rubble by a German sniper. His Love Interest uses a mirror shard to reflect sunlight right into the German's scope, making him flinch just long enough for Vasili to take a snap-shot at him and get away.
- In Game of Death, the enemy played by Kareem Abdul Jabaar has light-sensitive eyes. Bruce Lee gains the advantage by breaking holes in the walls to let the light in.
- Goldfinger. During the golf game, James Bond tosses a gold bar onto the grass just as Goldfinger is about to make his shot. The light reflecting off the bar (and the distracting sight of all that gold) causes Goldfinger to miss.
- Hook: The Lost Boys have one set of weapons that use mirrors to blind the pirates during the Final Battle.
- In The Hunger Games: Mockingjay Part 1, during the raid on the Tribute Tower, the lights suddenly come back on, blinding the team and alerting the audience that something is horribly wrong.
- Iron Man. When Iron Man is being crushed by Iron Monger, Tony lets off all his flares because he doesn't have anything else. It works enough to make Iron Monger let go because its pilot is momentarily dazzled.
- Jack Reacher. Reacher knows the villains have a master sniper working for them. He brings his own marksman, ex-marine 'Gunny' Cash, who says the sniper will be hiding behind one of the construction lights surrounding the quarry (Reacher notices Gunny has one eye closed, which Gunny explains is to preserve his night vision). Reacher asks if Gunny can't shoot out the lights, but that would only expose his position before all the lights were knocked out.
- Jason Bourne averts an assassination by turning a spotlight to where the sniper is hiding, causing him to miss his shot.
- In Jumanji, Judy blinds Van Pelt with a price scanner.
- Kick-Ass. During a Darkened Building Shootout, The Mafia mooks start a fire so they can see Hit Girl who's shooting at them with the aid of night vision goggles.

The remaining mooks all fire at the flashing light, failing to realise that Hit Girl is coming up behind them.
- In A Kid in King Arthur's Court, Calvin opens his CD player and shines the laser into a bad guy's eyes.

- During his final fight with Witch Queen, Kaulder uses some improvised flash grenades several times to knock the witch off-balance, bliding her for a moment every time.
- During the final duel in the first Lone Wolf and Cub film, Ogami faces off against his enemy in a seemingly fair fight. At the climatic moment, however, he bends down, revealing Daigoro on his back - wearing a plate on his forehead that reflects the sunlight straight into the foe's eyes.
- In the 1981 film Looker, a strobe light weapon doesn't blind its victims, but rather hypnotizes them which causes them to lose all sense of time.
- Lord of the Rings: This happens to the Uruk-hai at the end of the Battle of Helms Deep when the sun rises behind the charging cavalry.
- Now You See Me 2: Atlas uses a camera flash to blind a technician in the server room during the Octa job. Later, the crew shine lights in Tressler's eyes to prevent him from getting a good look at the inside of the hangar.
- The Outlaw Josey Wales. Use of this trope is lampshaded when Josey Wales attacks some outlaws, riding at them from the direction of the sun.
- At the end of Rear Window, the protagonist keeps the killer at bay shooting off a series of flashbulbs, momentarily stopping him blind. This allows just enough time for the police to show up within earshot.

- The protagonist of Barbara Kingsolver's Animal Dreams is haunted by a recurring vague nightmare about a blinding flash of light, accompanied by a "shattering pop." It turns out to be her neonatal memory of a camera flashbulb.
- The Black Magician Trilogy: Sonea pulls this off when being harassed by other apprentices at night. She doesn't want to fight back, because she's much more powerful and could hurt or kill them. Instead, she turns off her magical light for a few moments, so their eyes adjust to the darkness, then turns the light Up to Eleven. Her assailants end up temporarily blinded.
- Heleth in The ColSec Trilogy has superhuman night vision, but is photophobic as a trade-off. In the third book, a particularly bright light not only temporarily blinds her, but actually causes her to faint from pain.
- In Robert E. Howard's Conan the Barbarian story "A Witch Shall Be Born", Salome uses light to blind Tamaris's rescuers.
- Discworld: In The Fifth Elephant, Vimes' coach is accosted in a mountain pass where the sun has already gone down. Vimes gets out to talk to the robbers and takes the time to light his cigar. When "dark clerk" Inigo Skimmer chides him later for the grandstanding, Vimes' reply is "you mean when I closed my eyes and they had to look at a bright flame in the darkness?" In other words he destroyed their night vision, making them unable to see the crossbow-spring he used to kill the leader.
- Averted in The Dresden Files. While it's the first instinct of most wizards to call up light in the dark, not only does it not blind badass enemies, but it lights the wizard up as a target.
- Heralds of Valdemar: Kerowyn, the heroine of By The Sword, uses the combination of highly polished armour, mirrors, and some minor magic to amplify reflected light, to storm a Karsite position with few casualties. This is particularly psychologically damaging to the Karsite soldiers as they worship a Sun God.
- In the final book of the Inheritance Cycle, Inheritance, during Eragon's sparring match training against Arya, Eragon gets the idea to distract Arya during the pre-duel positioning so that she focuses on him, and doesn't notice he's putting his back to the sun. It works well enough to get in a first attack, but then Arya holds him off long enough to regain her vision, and she starts to win the spar.
- Tom Clancy uses this in a number of his Jack Ryan books. In addition to the standard flashbangs, Debt of Honor features a high-intensity blinding light weapon, stated to be a nonlethal weapon. It is indeed nonlethal, if horribly effective, when used on a mook. Then it's used on the pilots of enemy aircraft as they're attempting to land their planes.
- In John Gardner's James Bond novels, one of the modifications fitted to Bond's car is a high-intensity halogen flashbulb replacing the bulb that illuminates the number plate. This is used to blind pursuers.
- In the first book of The Legend of Drizzt, Drizzt floods the room with light to escape from his family (who are now trying to kill him). Being creatures who live their whole lives in the dark underground, the light is not only blinding, but painful as well.
- In the first Redwall book, one of Cluny the Scourge's first mistakes when trying to take Redwall Abbey is to pepper the defenders on the walls sunward, meaning that his bowbeasts can barely even aim where they're firing, all while the Redwallers return fire unhindered.
- A Song of Ice and Fire. During a Trial by Combat, Ser Gregor Clegane stands with his back to the sun to blind his opponent, the Dornish prince Oberyn Martell. Martell turns this against him by using a metal disc on his helmet to reflect the sun back into Gregor's vision slit.
- Subverted in James Follett's The Tiptoe Boys (later filmed as Who Dares Wins). The SAS soldiers rescuing their comrade's family can't use flashbangs because it will cause permanent neurological damage to the hero's infant daughter. They settle for making a "fucking great hole" in the wall so that each terrorist can be engaged by one commando. In the book, they take bricks out and leave only the wallpaper; in the film, they use detcord to cut their way through. It works.
- In Wings of Fire, Tsunami often uses her bioluminescent scales to this effect. It is especially effective because, even though all of the SeaWing tribe has scales that work like that, they don't use it to blind opponents. Tsunami was raised separately from her tribe so she ends up being a very unorthodox fighter.
- Agent Carter. Peggy Carter puts on welding goggles, then uses some kind of spy gadget to blind a corrupt Roxxon employee with a gun.
- Buffy the Vampire Slayer. Buffy just happens to be armed with a Flare Pistol when up against Initiative commandos wearing Night-Vision Goggles in a dark corridor.

- Doctor Who: In "The Daleks", the Thals baffle the Daleks' cameras with handheld mirrors.
- Highlander: The Series had a rogue Watcher who killed other immortals in complete darkness with night vision glasses. Duncan got the edge on him by blinding him with light from a match or lighter or something similar.
- Home Improvement Tim manages to rig an obscenely bright snowman decoration during the Christmas season it's so bright they need to put on goggles and Tim advises his family not to look directly at it.
- JAG: In "Sightings", this is one of two methods the UFO has of rendering people helpless.
- Life on Mars (2006). Time-traveling cop Sam Tyler embarrasses himself telling a witness that he'll be behind one-way glass when identifying some bank robbers. As he's in The '70s, we Gilligan Cut to the witness facing the Death Glaring suspects in the middle of the canteen. Naturally he balks at making the identification. At the end of the episode, Tyler rigs up some floodlights so the criminals can't see who is identifying them. However as the witness now has more confidence in the detectives after they saved him from a murder attempt, he steps boldly into the light to identify the robbers.
- Murdoch Mysteries: In "Convalescence", a weakened Murdoch turns the tables on his attacker by slipping his experimental night-vision goggles on her head. Designed to work in near darkness, they amplify the normal light in the room to the point where she is blinded.
- Person of Interest. In "Liberty", Reese uses a foil wrapping to reflect sunlight in a sniper's face so Shaw can sneak up and clobber him. In "The Devil's Share" he shoots a pile of flares he's left in a corridor to blind a SWAT-team with night-vision goggles.
- In an episode of Sherlock, John is trapped in a lab room. A hugely bright light is shined in his eyes for about half a minute, with his attempts to get away from it useless, and then, when the lights go almost completely dark, the afterimage of the light prevents him from seeing anything. Which is a problem when the demon hound is apparently in the room with him, about to attack.
- In Spartacus: Blood and Sand, Crixus reflects sunlight with his helmet into Theokoles' eyes, allowing Spartacus to get close enough to kill him. As Theokoles was an albino, his eyes were especially sensitive to light.
- Star Trek: Voyager
- In "Live Fast and Prosper" the Voyager crew comes up against a group of con artists who have been impersonating Janeway, Chakotay and Tuvok. Tuvok eventually comes face-to-face to with the man who is impersonating him and the con remains in-character, commenting that "Logic would indictate that neither of us has the advantage." Tuvok responds "Your logic is flawed," and shines a flashlight in his eyes, then stuns him with a phaser.
- In "Displaced" Voyager has been seized by aliens who are sensitive to light. They've dimmed the ship lights, so Chakotay turns them up to full brightness.
Myths & Religion
- There was a biblical battle that took place and overall the terrain was consistent no matter which direction you would attack from. So the attacker came around dawn from the east so the sun would be at his men's back and in the eyes of the enemy. This is actually a very valid tactic: if you can use it do so.
- In The Bible, when Jesus confronts Paul for the treatment of His followers, He approaches him in a beam of light, knocking him off of his horse. This trope ends up becoming a literal example as Paul temporarily becomes blind.
- Dungeons & Dragons:
- The game features a variety of spells that use light to blind and/or incapacitate an enemy.
- Certain races, particularly subterranean ones such as drow, have a light blindness trait that penalizes them for being outside in daylight.
- Defied by the sunmaster, a Prestige Class from the 3.5E supplement Lost Empires of Faerûn. The class feature for 2nd level grants immunity to blindness or dazing due to light effects, in addition to a few other powers.
- In Psionics: The Next Stage in Human Evolution getting hit with a flashbang grenade grants severe penalties to checks, tests, and defense, as it both deafens and blinds the target.
- Various spells in Fate of the Norns: Ragnarok can blind friend and/or foe. Some immortal warriors can notably create giant pillars of fire, dropping from the skies, burning and blinding their opponents.
- Mutants & Masterminds sports the Dazzle power which can do this for any sense.
- Similarly, the Hero System Flash power can temporarily blind any sense. The player is encouraged to define the particular mechanism (a target might be blinded with bright light, tear-inducing chemicals, or a direct hit to the eyes with an irritant; an attack on the sense of smell might be a pungent Stink Bomb or a nose-numbing vapor; etc).
- Shadowrun: Anyone looking at a flash-pak grenade when it's active gets an eyeful of bright, randomly strobing light for a few seconds.
- In the BattleTech Expanded Universe, the Particle Projector Cannon is noted as firing a blinding lightning-like particle beam that can disrupt sensors. However, combat vehicle viewscreens can filter out the light. In the second Saga of the Gray Death Legion novel, Grayson Carlyle pilots a PPC-toting "Marauder" Humongous Mecha with a blown canopy inside an abandoned factory. He alternates between eyes to avoid being completely blinded as he fires the PPCs, and by the end of the fight suffers from facial burns and corneal damage.
- Next to the usual flashbang grenades, Rainbow Six Siege features a GSG-9 operator that's equipped with a ballistic shield embedded with three rows of flashbangs, which enables the trooper to blind anyone who gets in front of his shield's periphery. Appropriately, his beta badge shows a Medusa and his callsign is "Blitz", German for lightning.
- In Vindictus, the secondary weapon Light of Palala is a flash grenade which stuns most enemies for a few seconds, looking confused.
- Some battlemechs in Mechwarrior Living Legends mount large spotlights on their shoulders, which can be used to blind players using the nightvision overlay when it's dark. When a destroyed mech goes nuclear, it sets off a huge, blinding mushroom butt which can be used for storming an enemy position if carefully timed. Particle Projector Cannons at night are blindingly bright, and have an EMP effect that temporarily disables the nightvision of whatever it hits.
- Alan Wake: The game's combat system is based entirely around using light (from flashlights, flares, flashbang grenades, etc.) to damage or render vulnerable the various enemies. Also, some NPCs react to the player shining a light in their face by shielding their eyes.

- Heroes of Might and Magic: Most iterations of the series have a spell called "Blind" that effectively works this way.
- Luigi's Mansion: Luigi must use his flashlight to shock ghosts so that he may inhale them into his vacuum.
- Neverwinter Nights: Well, it is based on Dungeons & Dragons, after all...
- World of Warcraft: PCs and bosses have abilities that can use light to completely incapacitate or at least hinder accuracy. A recurring element with bosses is the need to turn characters so they're facing away from the boss to avoid being blinded by the flash.
- God of War Series:
- Perseus in God of War II uses his reflective shield to blind Kratos several times in his boss battle.
- Aside from using it as a makeshift flashlight, Kratos can put Helios's severed head in God of War III to great use by blinding enemies with it. In fact, employing this strategy is how you're supposed to defeat Kronos the Titan.
- In Mass Effect 2, flashbang stun grenades are Kasumi's special power, unlocked once her loyalty mission is completed. With advanced training, Shepard can use these grenades as well. Donovan Hock's mercenary guards and the Shadow Broker's troops also make regular use of flashbangs. As a successful flashbang can not only stun you but also knock you out of cover, these minions can easily enter Demonic Spider territory.
- This is the basis behind the Pokémon move Flash, which can be used in battle to drop the opponent's accuracy one stage. Of course, that doesn't mean it is used very often, what with several other moves being able to do this with more success, and the relatively low benefit reducing accuracy has in the game.
- In Final Fantasy VI, Edgar Figaro can wield the Tool "Flash," a camera with a flashbulb as big as he is. It deals unblockable, defense-ignoring non-elemental damage and inflicts the Blind status effect on enemies.
- Armored Core 4 and 4 Answer gives you the 09-FLICKER Flash Rockets. These literally are flashbang in rocket form and having it set off anywhere near you means that you lose lock-on capability for some time. Very bad against close-range combatants like Anjou/Ange, and especially Shinkai. Getting hit by an Assault Armor in 4A will also produce this effect.
- Happens briefly early in Fallout 3, when your character leaves his underground vault for the first time.
- Subverted if you nuke Megaton; the player and other characters observing the explosion, since they didn't have eye protection, should have been permanently blinded, or worse, had their eyes melted out of their sockets.
- It only happens once in Fallout: New Vegas, when you first properly activate the Helios One facility, you get blinded for just one second.
- Wizardry: The Blinding Flash spell in the final trilogy. Simple and very effective throughout the early through middle parts of the games.
- Flashbang grenades are, appropriately enough, a common tool in your arsenal in SWAT 3 and SWAT 4. Just make sure you're out of the doorway when you use one and that your NPC teammates don't, y'know, just drop it at their fee—GAH! YOU FOOL!
- Battlefield 3 features the tactical flashlight and laser sight. The latter is a red laser that is primarily used to boost the effectiveness of hip fire, but also causes an annoying red spotlight to cover the target's vision if it is aimed at them. The former, on the other hand, is purely used for blinding foes. By blinding foes, I mean melting the eyes of the person controlling the target to a molten liquid and setting their hair alight.
- In The Darkness, Jackie can't effectively use his powers in well-lit areas. A Dirty Cop figures out Jackie is vulnerable to bright lights and uses a combination of flashbang grenades and floodlights to incapacitate him.
- Used against you quite a bit in The Darkness 2. You'll often have one of these thrown in to strip you of all your powers and then a follow up barrage of bullets just to ruin your day.
- A staple of James Bond games, most notably Nightfire and Everything or Nothing. Nightfire's flashbangs were a double-edged sword: if you didn't turn around, the screen would flood with white and obscure enemy fire.
- In the arcade game Roc 'n' Rope, the Climber's head-lamp worked like a camera flash.
- In Metro 2033, this is a gameplay mechanic essential to beat the Plated Nosalises. Since they dwell on the least-lit parts of the Metro, shining the beam of your flashlight on them blinds them and makes them stand still long enough for you to get a few shots off. And you will need those few seconds of advantage.
- Flashbombs are a useful tool in Thief, where they can temporarily blind an enemy who has noticed you, enabling you to make a getaway. Repeated use of flashbombs can also kill undead.
- AdventureQuest uses a variety of different uses of this trope for inflicting Blind. The late-game Ultraviolent Light spell takes this Up to Eleven, however. It's not ONLY a large, magical ball of light that works like a flashbomb— it absorbs ALL the light in the area (blacking out the rest of the screen), and THEN explodes violently (covering the entire screen in light). It's little wonder that it's both rather lethal and has the tendency to blind most foes for a very long period of time (unlike most Blind effects in the game, which operate on a turn-based timer, UL's status works until the victim pulls off a successful save roll) It's also an inversion, too, as the darkness-based hit can inflict Blind even if the explosion itself misses (the save roll is weaker than a normal save roll if only one attack hits, but if both connect the save roll is tougher than usual).
- Dungeons & Dragons Online has the Flash Bang by name, a dazing and blinding grenade that allows a form of non-smoke Smoke Out for Ninja Spies.
- Weaponized as a secondary function Spark Manbow in Rockman 4 Minus Infinity. If you hold up when you press the fire button, Mega Man holds up a lightbulb and causes a bright flash of light to cover the screen, which makes enemies stand still for a few seconds.
- The opening cinematic of Fire Emblem: Radiant Dawn has Michiah using her Light Magic to blind a group of Begnion soldiers trying to arrest her and Sothe.
- In The Matrix: Path of Neo the SWAT teams use Flash-bangs against Neo and the other rebels to try to temporarily blind, disorient and confused them. Thus one of the in-universe reasons for Cool Shades.
- In the second level of Splinter Cell Pandora Tomorrow, there's a courtyard overseen by a guard with night-vision goggles, so to avoid being seen, you have to be illuminated by the searchlights. The penultimate mission has periodic lightning flashes outdoors that temporarily blind Sam if his goggles are equipped.
- Excalibur in Warframe has a skill in which he unleashes a blast of light from his Exalted Blade that blinds enemies around them, stunning them and making them vulnerable to Finishers.
- Stryker uses this to initialize his X-Ray attack in Mortal Kombat 9. Prior to initiating a beatdown with other standard-issue police weapons, Stryker forces his opponent to their knees by blinding them with a flashlight. Notably, this attack works on everyone, including supernatural demons, the already blind, and people wearing sunglasses.
- The flashlight in Dead By Daylight is used exclusively to blind the killer when pointed at his face. The hunter gets a pure white screen with only the HUD visible.
- Bob and George: Someone tries to use this against Bob. Alas for him, Bob is wearing sunglasses.
- The Beast Legion: Brilight uses this particular trick twice in Issue 4 against Dragos  , 
- In Far from Home, pirates use high-intensity flares in missiles so as to take the heroes alive.
- In Homestuck, the skin of rainbow drinkers brightly glow, and can turn this effect on and off. In one of the Paradox Space spin-offs, Kanaya suddenly does so in order to escape an awkward conversation.
- The vampires in this web-novel have eyes that can see perfectly in the dark, but are blinded by light. Vampires can operate during the day even without the big bulky goggles they normally wear, but they get headaches and they can't really see. Sudden flashes of bright light (such as an angel's daybreak) can actually knock them unconscious.
- Inverted, actually, with the angels. They can see perfectly in bright light, to the point that they tend to stare directly at the sun when bored. However, they have basically zero ability to see in the dark, so they have to carry around nightvision goggles to even see in the shadows on a sunny day. Of course, they have the ability to emit bright light, so it's not really a big deal as long as they don't have to worry about blinding anyone.
- In G.I. Joe: A Real American Hero, Zartan hates sunlight, although just how much it pains him seems to be Depending on the Writer.
- In the Gravity Falls short "Mabel's Guide to Color", Mabel tries to show Grunkle Stan a rainbow by reflecting one from the waterfall into the window of his office with a mirror. The results...were a bit more than what she was expecting.
"Nothing brightens a dark room like light from a window! Time to open the wind- OH NO!!! WHY?!? WHY IS THIS HAPPENING?!?!"
- My Little Pony: Friendship Is Magic:
- In "It's About Time", Twilight Sparkle is scanning the skies with a telescope. She accidentally looks directly into the sun and is blinded in one eye. She has to wear an eye-patch for the rest of the episode so her eye can heal.
- In "Inspiration Manifestation", Rarity turns the streets of Ponyville to gold. The sun reflects off it and blinds several citizens.
- In The Smurfs episode "Now You Smurf 'Em, Now You Don't", Papa Smurf used light shone through a magnifying lens into a magic crystal ball to blind the trolls digging tunnels underneath the Smurf Village to capture the Smurfs.
- Star Wars Rebels: In "The Holocrons of Fate", the holocron fusion unleashes a brilliant white light that blinds everyone except Kanan, who, ironically enough, has his vision temporarily restored (albeit crudely) by the same light.
- Used in Trollz when ogres are sensitive to light. Good thing Sapphire's spell misfired earlier and made her feet glow.
- World War I / World War II: Attacking out of the sun was a popular tactic for both fighters and dive-bombers.
- During the age while armies still utilized campfires at night, it was not uncommon for those to be used as a means of deception. Merely looking at a light source at night temporarily ruins the eye's low light adjustments, meaning that while looking at such a campfire (or for that matter any other light source at night), it was impossible to actually see the people (if any) that existed around it; only the light source would be visible. Armies got pretty creative with this back in the day, from setting up false camps (the enemy won't know there's no one by the fire until it's too late), to lighting a minimal number of fires to hide their number (sometimes going as far as just one big fire; good luck guessing how many people are sharing it), to ordering the camp to make several times its number in flames. A cunning general may even combine the various methods, essentially rendering the enemy's attempts to scout his position at night futile or downright counterproductive. Even in warfare, there are uses for fire other than killing.
- One of the armored vehicles used in the Normandy landings in World War II was essentially an outdated tank with the gun replaced with a very high intensity lamp, entirely encased in the turret save for a narrow vertical slit. The turret would pan back and forth, perodically painting the German defenses with blinding light to make it impossible for them to see the troops on the beaches. They also had various filters they could put onto the light while in action, so as to make it harder to determine how far away the vehicle was if you wanted to put its lights out. Unfortunately the weapon was so secret its use was minimal, as few officers were aware of its capabilities.
- In World War II, the British "hid" the Suez Canal with an array of spotlights and shifting reflectors intended to dazzle the eyes of bomber pilots. When they tested it by having two British planes fly into the area, they found the effect disoriented the pilots so much that both planes nearly crashed — just from flashing lights. Best part? This was just one stunt thought up by Jasper Maskelyne, War Magician. Eventually, a chain of twenty-one searchlights covered the Suez Canal for its entire length. When illuminated, they created a curtain of swirling light over more than a hundred miles of Egyptian sky. In the following months enemy aircraft made a number of attempts to penetrate the curtain, and failed, and the canal remained open to Allied shipping throughout the war.
- Or so he claimed in his biography — recent research has shown the dazzle weapon was never actually built except as a prototype.
- The LED Incapacitator, a rather recent non-lethal weapon which works by creating a bright pulsing light with continuously changing colours to dazzle and disorient an opponent when violence is not permitted. Readers of The Final Programme may find this strangely familiar.
- A more mundane example: pilots who fly at night have to avoid any bright lights for upwards of 20 or 30 minutes before a flight in order to maintain their night vision. Their cockpit lights are run at the lowest setting that lets them see their instruments, because any bright light will force them to start all over again trying to readjust to the darkness of night. As a result, airports will often actually be much more dimly lit than some folks might expect, as the last thing they want to do is to blind a pilot who is trying to take off or land.
- Similar to the above, go out some night to visit a group of stargazers out doing their thing, and you will quickly learn that they do not like it when folks use any bright or white light near where they are stargazing. Stars are bright, but they are not that bright compared to closer light sources on Earth. The use of red-filtered light is common as it does not have the same negative effect on human night vision.note
- Several people have gotten arrested for shining their bright green laser pointers into the nighttime sky and dazzling or temporarily blinding pilots overhead. Particularly if the plane is taking off or landing. There was serious talk of outright banning the sale of laser pointers in Britain after someone used the same trick to make an oncoming car swerve off the road and hit a tree, and in Spain using them against pilots or drivers supposes a fine of up to €600,000.
- Laser pointers can even cause permanent retinal damage.

- The Protocol on Blinding Laser Weapons, Protocol IV of the 1980 Convention on Certain Conventional Weapons, was issued by the United Nations on 13 October 1995. It came into force on 30 July 1998. This bans weapons that cause permanent blindness. Blinding as an incidental or collateral effect of the legitimate military employment of laser systems, including laser systems used against optical equipment, is not covered by the prohibition of this Protocol. It also defines blindness as an irreversible and uncorrectable loss of vision which is seriously disabling with no prospect of recovery. Serious disability is equivalent to visual acuity of less than 20/200 Snellen measured using both eyes. So "minor" permanent damage is not covered. Temporary damage is also not covered.
- It is common for gun owners to use them with a flashlight attachment, with output usually above 200 lumens. Their utility is twofold - they help with target identification in low light, and when you turn the light on in the target's face at close range, it's hard-pressed to accurately return fire. Even the handheld models, if they surpass the 200 lumen minimum (and even as far back as 2011, even ones powered by at least two AA batteries can do it), can be used for self-defense in places where firearms and knives are more restricted.
- Magnesium burns easily and very, very bright white, producing ultraviolet light as well. It can permanently damage the retinas; working with pure magnesium powder requires safety glasses with welder protection.
- It is now believed by many that the so-called "heat ray" used by Archimedes to help defend Syracuse from the Romans in the 3rd century BC would not work to set fire to ships using parabolic mirrors. Instead, it is believed that Archimedes used the mirrors to blind the Romans, making them unable to fight effectively.
- This is the reason that, in most jurisdictions, you are forbidden from driving with your high beams/brights on when there is oncoming traffic (i.e. if you are in a lane going one way and there are cars in the lane next to you going the other way). If you have your high beams on, the light could dazzle other drivers and cause an accident.
