Playing it may just be worse then seeing it. Here are examples of Eye Scream from video games.
In Killzone 3's "Brutal Melee System" you can do this in two very fun ways: stabbing an opponent in the eye and (somehow) gouging out a Helghast's eyes through his goggles.
In Call of Duty: Black Ops during the Baikonur level, after Weaver gets compromised and tied to a chair, Kravchenko stabs him in the eye. He survives, unlike Shepherd at the end of Modern Warfare 2.
Within the Wii version of Sonic Unleashed's final battle, Super Sonic damages Dark Gaia by slamming into the beast's giant eyeballs. Before that, in the PS3/Xbox 360 version, he uses repeated homing attacks in its eyes. With a twinkly smile.
In Demons Souls, the Maiden in Black has her eyes covered by wax that's melted into her skin, blinding her. It's unclear that if she was born this way due to her being an incredibly powerful demon or if she if the wax was more of a result of her being the keeper of the Nexus. If the latter is the case, it's also unclear if she lost her eyes before coming to the Nexus, she still has her eyes under the wax, or if she lost them due to the waxing.
In a flashback scene at the end of Saejima's episode in Yakuza 4, we are treated to a very, VERY squicky scene where a bound Goro Majima refuses to bow down to a low-level yakuza that's in charge of restraining him, and the yakuza drives a foot-long knife into Majima's left eye.
In many The Legend of Zelda games there are enemies that can only be killed by hitting their eyes. Lots of them especially in (but not limited to) the 3D games.
And not just enemies: some games feature switches resembling eyes that are activated by shooting them with arrows.
It's implied that the Link of Ocarina of Time eventually loses an eye - as the Hero's Shade in Twilight Princess, one eye is dimmed out, and his wolf form has the same eye scarred shut.
Yuri's unfortunate first encounter with Valantin in Infinite Space ends in tragedy as he finds himself with a 5-foot blade in his left eye. He gets better.
Castlevania: Curse of Darkness has an alluded-to near-miss of this. See that scar over Trevor's left eye? Dracula got testy.
Judgment made him lose the eyeball (thus making HIM look more like a pirate than Faust-VIII-lookalike zombie Grant).
The cyclops is only vulnerable to headshots. But it's a cyclops, so we know they're actually eyeshots.
Balore's weak spots are his eyes. Always. And Dawn of Sorrow makes him way less pretty.
In Dead Rising a Psychopath meets his end when a statue tips over onto him. The statue is holding a real sword. Guess where that sword goes.
In Dead Space, the Captain of the ship has gone mad and the doctor declares him unfit for duty. He picks up a needle with a sedative, but the Captain jerks as he tries to get free, and the needle is jammed into his eye.
In Dead Space 2, this happens twice. Once to Ellie at the hands of Dr. Stross ("You owe me an eye, you bastard!"), and once to Isaac if you fail to get the needle in the right place in a minigame near the end of the game. (It's still a nasty case of Eye Scream if you do get the needle in the right place. You just don't die.) It's made worse by the fact that you're in control of it the whole time. Both of these are preceded by the rather nightmarish little chant "Cross my heart and hope to die... stick a needle in your eye..."
Dead Space 3 tops them all; you kill the Final Boss by throwing things into his eyes. Seems mundane, but the final boss is a post-Convergence Necromorph the size of a moon, its eyes are several hundred feet wide, and the things you throw into its eyes are Red Markers about 30 feet tall. Upon impact, the eyes burst open into a tidal wave of blood and fluid. Here, you make the closest thing to an unrelenting, timeless Physical God feel pain.
In the original Diablo's intro, you see a close up of a crow picking out the eye of a decaying body. While not looking too realistic by today's CGI standards, that was a pretty unpleasant scene at the time of release.
In Dwarf Fortress, eyes are damageable (and, in some cases, targetable) organs.
However, in the current version bugs mean they can't be removed and will rapidly recover any damage they receive.
Throughout the first three levels of Eversion, there are gems hidden in Mario-esque floating blocks with happy faces on them. Level 4 lets you know exactly where the game is headed when you are forced to jump into one and its eyes pop out of its sockets as you instantly evert from Sugar Bowl World 4-1 to the completely terrifying World 4-5.
In Fable on the Xbox, the main character's sister has her eyes cut out by bandits when she refuses to tell them where you are.
In Fable III, during your first encounter with the Crawler, when you find Walter after his disappearance, he is covered by a dark goo, and his eyes seem to be bleeding said goo. More creepy than Squick-inducing, though.
In the first two Fallout games, aiming for the eyes is not only possible but one of the most effective ways to dispatch enemies.
Fire Emblem Nergal, not torn out, GOOGELY EYED TWITCHEYNESS!
In Fatal Frame, one of the items you can find is a mask with large spikes in the eyes. It's revealed that girls are blinded with this device for a horrific ritual to close hellgates. What's worse is you can try to use the mask yourself, though many never had the courage to find what happen if you press the "Use" button.
The sequels also have cases of Eye Scream, especially the Needle Women in FF 3 who sewed their own eyes shut.
In a flashback in Final Fantasy X we see how Auron gets blasted into the face/left eye by Yunalesca when trying to avenge Jecht´s and Braska´s deaths Well, at least he got his EyepatchSunglassesof Power after that
In Heavenly Sword, this happens to King Bohan very close to the end of the game, after the Raven God pecks his eyes out as a punishment for Bohan failing him.
From Mechwarrior 4: Vengeance "[if they escape] then I shall find the men responsible and feed them their own eyes!"
In Metal Gear Solid 3, Snake's been captured, and Volgin tells the Boss to cut out his eyes. She doesn't. He loses his eye when Ocelot, doing his Russian-roulette-juggling thing, is about to shoot EVA. Snake tackles him, and the gun goes off right by his eye, damaging it irreparably.
Just so you have the proper context, Naked Snake, AKA Big Boss was well known before this game came out for having only one eye. That makes the above instance very uncomfortable to watch, as you know he probably won't be getting saved in the very last moment.
Subverted in Metroid Fusion with Nightmare; when he increases the gravity, it seems his eyes are bleeding, that is, until the mask pops off and it turns out his face is melting.
Samus herself gets an Eye Scream in Prime 3: Corruption, when her face becomes increasingly scarred as the Phazon corruption progresses. By the time you hit 50% corruption or so, not only are her eyes glowing blue, but the pupils have turned radioactive green. It's even squickier in the trailer video, when you see the Phazon flowing into her eyes from the inside.
The "phazon in your eyes" thing is still in the game. Go into Hyper Mode and let yourself get corrupted. It'll probably be the last thing you see, though.
In No More Heroes, Travis Touchdown blinds Harvey Moiseiwitsch Volodarskii by throwing his beam katana at him, cutting out both of his eyes.
Wich leads to the strangely funny line "It's dark! Somebody turn on the lights! I can't see shit!" Right now, it won't sound funny. But with his accent, it's a whole different story
Very rarely in the sequel, the Tsubaki Mk III, whoops I mean Carmelia Mk III, will slice an enemies head in half, right about eye level. Least of their worries, but still...
In Planescape: Torment, The Nameless One has a special equipment slot called 'eyeball'. Its default contents are, well, what you'd expect, and you can replace it by... Well... You can connect the dots yourself. At no fewer than two occasions in the game you can also lose the other eye for story reasons, the first time by tearing out your eyeball by hand and replacing it with an old eyeball a previous incarnation of you had torn out and stored somewhere and the second time by having Ignus pluck it out (again, by hand... And this time, said hand is on fire) to use it as a repository for magic you can learn.
Three times. If you take the right dialogue options with Ravel Puzzlewell, she'll stab you in the eye with a claw and hook it out, then stuff a black-barbed seed in the eyeball and pump it full of magic before giving it back to you. This is one of the many statistic boosting choices in the game.
Planescape Torment: The game where having your eyes poked out gives you stat bonuses.
One time used for humor. One of the sensory stones contains the mind-numbing tedium experienced by a student in what was apparently the most boring lecture of all time. At one point, the student considered jamming his quill into his eye for a change of pace (though if he had actually done it it would have been a completely different sensory experience in the stone).
Den Mother: Enough! It is time for me to pluck out your eyes! Raz: You can't — that is the purpose of the goggles!
In Silent Hill 3, the hint for the Hard Mode hospital keypad puzzle (Guide Dang It!), is a poem about poking out someone's eye, drinking the blood from the crushed eye, and biting off their tongue and left ear.
Waxworks: many of the standard deaths involve this. Examples include a spike pit's spike goring you right in the eye, or a plant mutant's seeds pushing your eye out of its socket as they grow inside you.
In Thief: The Dark Project Garrett's eye is torn right out of his head. The empty socket is even shown later on, albeit briefly.
No-Face in Twisted Metal: Black got badly beaten in a boxing match. When he went to a back-alley surgeon to get his face put back together, he chose badly; the surgeon had lost $20,000 betting on him, and took out the man's eyes and tongue as revenge while he was out. We get to see his eyes falling onto a tray. Thankfully, in his ending, No-Face gets his revenge - punching the doctor in the face with a needle-loaded boxing glove.
Also, Calypso in his more recent appearances has a missing eye, prominently showing off the gaping hole where it used to be.
the white chamber... Hoo, boy. There's an FMV devoted to a decapitated head with its eyes missing, and said eyes open. And you find the eyes in a sealed box. Even with the eyes back in, it's not a pretty sight.
Also, there's a console which the player must use to gain access to a room. It requires a color code that's acquired after a certain event, and if the player tries to use the code before they are supposed to, the aforementioned head appears, scowling and covering the screen, with the words 'not yet' carved into its empty eye sockets.
In the cinematic for "The Gods of Zul'Aman" that came with Patch 2.3 of World of Warcraft, a High Elven soldier prepares to cut out one of Zul'jin's eyes as a way of adding insult to injury. The action fades to white just as the point of the dagger is a mere centimeter from Zul'jin's eye. Being atroll Zul'jin should have been able to regenerate but it seems this was somehow forgotten.
Also, the icon for one of the Rogue abilities, Cheap Shot, is a knife about to plunge into an eyeball, implying that what is "cheap" is that you're stabbing them in the eyeball.
In Yggdra Union, when Milanor is rescuing Yggdra from the prison in which she's held captive by Gulcasa, Valkyrie Aegina cuts his escape. Elena, former assassin of the Bronquian Empire, sneaks behind her troops and fires her crossbow... Hitting Aegina in the eye. Later on, when you meet Aegina again, she's wearing a bandage on her left eye.
In the backstory, this happened three separate times to poor Nessiah. First, his real body was blinded by the gods as part of his punishment for disobeying them and not fighting in Ragnarok. Second, his contract with the Yumel required him to sacrifice an eye to get their help in mastering his magic. And finally, he tore his remaining eye out in order to complete the Gran Centurio. (Yes, he was that desperate at the time. And insane.)
In First Encounter Assault Recon, after Jankowski's disappearance in the second level, you will occasionally see a "phantom" image of him...with his eyes gouged out. Whether or not he's actually dead though, is up in the air.
In Grim Fandango you have to use your scythe against the eye of an octopus, granted, it was protected by a crystal, but the fact that it breaks and shows blood afterwards...
In Fate/stay night, inflicting one of these on Enfant Terrible Illyasviel fully cements Gilgamesh's status as the Big Bad of the Unlimited Blade Works scenario. Particularly vicious, as he slashed her across the face with a sword, but only so she would be blinded while he continued to torment her.
One of the artifacts you're supposed to collect in Bloodrayne is a demon's eye which forcibly implants itself upon collecting. From Rayne's reaction to this, it's...not pleasant.
In the Nightfall campaign for Guild Wars, the mad god of secrets Abbadon and his servants have a thing for eyes. His favorite minion begins growing extra eyes on her forehead in imitation of her master, and her favorite threat/curse is "Abbadon will eat your eyes."
In Ōkami, the locks on doors in dungeon take the from of a demonic-looking face, with a large singular eye and the pupil shaped liked a keyhole. It doesn't react/end well, when Amaterasu brings a key along.
In World At War, at the very beginning of the game, a Japanese officer puts out his cigarette in a captured Marine's eye after he refuses to break under interrogation.
Timeslaughter has an intro where the man who becomes the final boss has an eye removed with a drill - although that's not too much in such already Gorn-tastic game.
In The Hunt featured a giant living statue as a Puzzle Boss. Your submarine had to make floating blocks of stone drop on its head. Once damaged enough, the stone covering the statue's face is destroyed, showing the flesh and bones underneath, and its eyeballs dangle out of their sockets. It doesn't help that he gains an attack where it spits out four homing eyeballs.
At the beginning of Overlord II, shortly after the frozen Overlad arrives in the Netherworld, Quaver gets his eye stuck to the ice. And when Gnarl orders that the ice be thawed by fire, Quaver pulls away fast enough to leave the eyeball behind. Ouch.
Assassin's Creed II took the counter kills from the first game and jacked the brutality level up to eleven. Countering with Ezio's hidden blade will occasionally result in both blades being jabbed through a guards eyes. You can't really make out much but really the dark red spurts of blood from both sockets are enough.
There's also the fact that Mario Auditore (Ezio's uncle) is blind in his left eye, with a scar around said eye. The injury itself is only elaborated on in the Facebook spinoff Project Legacy. In one mission (before the events of Assassin's Creed II), Mario was cut in the face by a bladed pendulum, causing his eventual blindness. To make it worse, there is even a picture showing Mario with the newly acquired injury, because we needed to see that.
There is also an unique Assassination move done by the Footpad (from the Brotherhood multiplayer) where said Footpad slashes the target in the eyes with his weapon before stabbing the target in the throat. The move's nickname? "Blinded and Helpless". Quaint.
Brutal Legend unsurprisingly has a good one. Go ahead and lose the RTS battle with Doviculus (if you dare!) The resulting losing animation quickly switches to Eddie's point of view just as the emperor tells you he is going to make a necklace with your eyes then thrusts his fingers into the screen as it turns to black.
Done in Kingdom Hearts: Birth by Sleep of all places, where Braig's fight with Terra ends with Terra firing a blast of dark energy right into his eye. Well, now we know where he got that eyepatch.
Some of the bosses in the Kirby games have very large and prominent eyes, and some are little more than just eyes, so attacking these bosses invokes this, especially if you do it withthe Master Sword. And then, there's Zero. To elaborate, Zero rips out his own eye in a fountain of blood. In a later game, you fight Zero Two, and dealing damage to his eye results in puffs of more blood.
Also worth noting is that recurring enemy Waddle DooDummied Out "appearance" in Kirby's Block Ball has its eye blown off in its death animation.
In Shin Megami Tensei III: Nocturne, after the world goes kalooey, you wake up, getting a first person view of a kid holding a bug... then he drops the bug, right into your character's eye (and with the first person view, it's like it went into your own eye).
Ironically enough, "Chikktika" is a combat drone, and those are shaped roughly like eyes.
Also, in the Mass Effect 2DLCOverlord, when you finally get to the cause of all trouble, David Archer, we find him suspended in some kind of harness with probes sticking out of, among other things, his eyes and holding them open. Think this picture, only with more focus, lingering, and different angles in the course of the ending cinematic.
According to Mordin, a batarian religion considers this act deeply insulting. Since they believe souls exit through the eyes when the body dies, removing or destroying the eyes is a terrible act of desecration.
Which gives some extra chilling factor to Renegade Shepard's payback on a racist batarian bartender who tries to kill him or her with a poisoned drink — he or she forces the bartender in question to drink his own nasty concoction, and threatens to "blind him one eye at a time" if he doesn't follow through.
At the end of the third episode of Duke Nukem 3D, Duke kicks the eye right out of the Cycloid Emperor's head.
This part was recreated in the prologue/video-game-within-a-video-game level of Duke Nukem Forever, only in this case the Cycloid Emperor's eyeball was on the ground, but still connected to his head.
In Shinobido, Zaji the Blackhawk has only one eye left and wears an eyepatch. Gamuran took out his other eye during the attack on the Asuka village by throwing a sharp wooden piece at it.
In Robinson's Requiem, this can potentially happen to the hero: one or both of his eyes can be damaged by various hazards, leaving him partly or completely blind in that eye. Or both.
The Hunter of Left 4 Dead has a character design that suggests some kind of eye damage; his eyes are thickly crusted with blood. The character model has no eyes at all, but it's possible that they just aren't rendered because his hood would obscure them from any in-game camera angle. In Versus mode, you can see fine while playing as him, but this could just be for the player's convenience.
In Snatcher, the iconic Gross-Up Close-Up of the rotting corpse involves its yellowed, shriveled eye dropping out of the socket.
A major plot point in Amea. As part of their attempts to escape life's hardships and begin a new, false life, The Master Eye's cult have all ritualistically removed their eyes and replaced them with artificial ones (likely of the Master Eye's own design) that wipes their memories beyond the bare essentials, thus letting them begin a new "life" as the Master Eye's slave. When Amea, who had initially joined the cult due to Parental Abandonment, learns this, she decides that she's not going to run away anymore and face whatever life throws at her, and shows this by ripping out her fake eyes.
Several characters in Mortal Kombat 9 have EyeScreamy X-Ray attacks, particularly Reptile (who pokes his opponent in the eyes), Kitana (who stabs her opponent in the eyes with her fans), Baraka (who stabs his opponent clean through the head through the eyeball), and Skarlet (who kicks her opponent in the eye with the heel of one of her Combat Stilettos).
Pops up a few times in Dragon Age II, usually with throwing knives. The best one is the conclusion of the Orsino!Harvester battle. Hawke leaps onto the beast and stabs it in the eye again and again. Then Hawke rips out its head and stomps it to death.
Zevran gets a Crowning Moment Of Awesome when an Antivan Crow runs at him from behind, sword raised. Barely turning, he flicks Murder Knife at the man, who slows to a stop and keels over, revealing the hilt protruding from his left eye.
One of the dead girls in Kara no Shoujo had her eyes cut in order to have it with tears of blood in order to mimic something from the Divine Comedy.
In EarthBound, one of the earlier enemies (yes, early in the game), a crow, have their attack read as a peck to the eyes.
Excerpt from text:His knee jerked and he felt blood trickle down his leg. In pain his head fell slightly forward. It took him a while to realize his eye had ruptured and begun to leak.
Skullgirls has a momentary, but haunting example in Peacock's individual storyline. A short flashback from Patricia's perspective shows us one of the slave traders who captured her, his thumbs reaching for her eyes. Then, they close in— suddenly, the screen goes red as a sickening squelch is heard.
Diminished a bit by the fact that she can grow new eyes as mage though.
Fallen London has sorrow-spiders, which are spiders that bite out the eyeballs of sleeping people. (Or people who're drunk enough to fall over.) They get their name from the tears that flow from the remaining eye. Also a milder example, the Correspondence can make your eyes bleed if you read it.
Mr. Nutz has a grimacing giant as one of the more memorable bosses in the game among players. One of his methods of attack is to ooze the eyes of out his head, although new eyes will grow in place of the old ones each time he does it.
The Valve logo from 1998 to 2006 depicted a man with a valve lodged in his eye socket.
In Super Street Fighter II, take a good look at Zangief's defeated portrait... What the HELL did your character do to Zangief's left eye?! Whatever it was, it looks horrible.
During the introductory mission for Borderlands 2, Robot Buddy Claptrap gets his eye ripped out by the game's first boss, a bullymong named Knuckle Dragger, and he tasks you with helping him get it back.
At some point in the game, Handsome Jack talks to the player about the time a man tried to attack him with a spoon. He then proceeds to laugh about how he then took the spoon and gouged out said man's eyeballs in front of his children.
Rugal Berstein has been on both sides of the trope. In KOF 94 we learn that he not only killed Heidern's family and squad, he also plucked out one of his eyes. And on the other hand, in KOF 96 it's explained that Goenitz sliced out Rugal's eye when trying to kill him; impressed that Rugal survived a fatal attack, Goenitz then gave him some of the Orochi power. Which would later kill him for real.
In The Witch's House, there is a book you can read called "The Book of Death" that will cause the main character's to scratch her own eyes out.
In Mad Father, there is a puzzle that requires you to retrieve a girl's missing eyes.
At the beginning of Brain Dead 13, Lance pokes Fritz's eyes, prompting him to cover them... too bad that he has Hook Hands.
Also, in one death scene, Fritz will approach Lance from behind, poke him in both eyes with his hooks, and proceed to rip him apart vertically, putting new meaning to the words "splitting headache".
In the Dynasty Warriors series, Xiahou Dun's Eyepatch of Power stems from him getting hit in the eye by an arrow. Unlike King Harold in the Battle of Hastings however, who simply dropped dead, he remained standing, pulled the arrow out and ate the lost eyeball. Not only does this prove that Xiahou Dun is Made of Iron, but it also provided a defining (if disgusting) moment in Dynasty Warriors.
Battletoads: Stage 4 of the arcade game features enemies named Ugly Mugs that need to have their eyes knocked out before smacking them in their ugly mugs.
In Pikmin 3, you can have Pikmin attack Bulborb eyes to render them incapable of attacking.
In the Animal Crossing series, shaking trees sometimes results in a beehive falling out, leading to the pissed-off bees chasing you. If they catch you, they'll sting your eye, leaving it puffy and swollen. Fortunately it's not permanent. Taking a rest (read: saving and quitting) or using some medicine will fix it.
Serious Sam 3 BFE has Melee Grabs, a type of Action CommandOne-Hit Kill that generally affects weaker enemies. Performed on a Gnaar, he will grab it, shove his hand into its eye socket, and rip out its single large eyeball, which can then be thrown at other enemies.
In what may be convergent evolution in gore, DOOMGame ModBrutal Doom has executions, available through use of the Berserker Pack. The one-eyed Cacodemons can be executed by the Marine reaching into its face and tearing out its eye with his bare hands.
In Crusader Kings II, characters in the Byzantine culture group can blind prisoners. This inflicts them with a malus to stats and gives their character portraits black, gaping holes in their sockets.
