Eyes have long been an important part of the Muppet aesthetic. For example, one of the most distinctive aspects of Kermit the Frog is his eyes, originally made from ping-pong ball halves and with unique cross-lined pupils.
The placement of the eyes on a Muppet character is key to the success of the character. In The Art of the Muppets, the Henson Associates staff wrote, "Perhaps the single most important aspect of the Muppet look is the set of the eyes in relation to the nose and mouth. The Muppet people call this the 'magic triangle': correctly positioned, it creates a central focal point essential to bringing a puppet to life in the eye of the camera -- and therefore the viewer." 
The development of this concept is often credited to Don Sahlin, chief architect responsible in many ways for the basic look of the Muppets.  Jim Henson explained the importance of eye placement: "It would be the last thing [Sahlin] would do, and he always wanted me there, to make sure it was right for both of us -- making sure the eyes had a point of focus, because without that you had no character." 
The focus of a Muppet's eyes depends on the placement of the pupils. The pupils are rarely in the exact center of the eye; instead, they are placed toward each other, making the character slightly "cross-eyed." This creates the illusion of focus, and makes it easier for the puppeteer to emphasise what the character is looking at. 
Because the eyes are such an essential element to the mechanics of the characters, Muppet builders usually wait until the last minute to add the eyes. 
The eyes of Muppet characters have often been broad and inviting, in the manner of cartoon character's eyes. Much in the manner of newspaper cartoonists, the size of the character's pupils have been a useful means of telegraphing a character's age. Sesame Workshop has explained this concept in a 2006 newsletter: "Muppet designers use different sized pupils depending upon how young or old they want a Muppet to look. The smaller the pupil, the older the Muppet looks; the larger the pupil, the younger the Muppet looks." 
When the Muppet designers created the "Land of Gorch" characters for Saturday Night Live, Henson insisted on giving them taxidermy eyes -- realistic-looking glass eyes used for stuffing animals. The eyes lent a more naturalistic look to the characters, contrasting with their general abstract nature. 
Later productions used taxidermy eyes to blend the look of a real animal with comic anthropomorphism, as seen in such characters as Eliot Shag or Jake the Polar Bear. Creature Shop productions The Dark Crystal, Labyrinth, and Dinosaurs used taxidermy eyes almost exclusively.
For the majority of Muppet characters, the eyes are fixed in certain positions and essentially static. Since Whatnots and Anything Muppets have their features re-arranged frequently, the eyes are simple attachments. Once tacked on, the eyes remain there unless forcibly removed by another character. These eyes have no moving parts. Thus any eye contact or movement is generally an illusion created by the puppeteers through performance, or through calculated manipulation and clenching of the puppet's face at key moments. The most recent example of this clenching method is evident in Elmo -- performer Kevin Clash is able to make the character look up in pondering or appear to raise an eyebrow by slightly adjusting the structure of the puppet's head where its eyes are attached.
For other characters, a variety of techniques have been used, both sophisticated and simple. Cookie Monster, for example, has googly eyes, created by pinning the pupils loosely onto the eyeballs, which gives him an excitable look and makes the character appear more animated.
Other creations, such as Big Bird, Animal, Mr. Snuffleupagus, Hoots the Owl and Telly Monster have complex eyes with lid mechanisms, which can open, close, expand or contract to create different expressions. Mahna Mahna and Floyd Pepper have had blinking eyes, unique in their design in that they are constructed simply as hollow "sockets," while in his debut in The Frog Prince, Sweetums' eyes lit up. One of the more advanced techniques used on a simple Muppet character is in the eyes of Wembley Fraggle. His spherical eyeballs are rigged with a mechanism that allow his pupils to appear to move within the realm of the eyes' white space. Unlike Sam the Eagle's pupils, which only move left to right, Wembley's can move in any direction, and often in a rotating manner to create the illusion that he is "rolling his eyes."
Still other characters are expressive by means of the material around their eyes. Bert's eyes have always been fixed, but his brow is extremely mobile. Dr. Teeth wears a pair of sunglasses which consist only of an upper half, suggesting eyelids at rest for a laid-back appearance, but which can be flung back at a moment's notice to telegraph shock or excitement.
In some cases when a scene requires total darkness (such as the electricity going out), this is done by using standalone eyes resembling the character's eyes on a stick against a black background, a variation of the typical cartoon convention of eyes floating against the darkness. This can be seen in a 1969 sketch when Ernie and Bert blow a fuse running too many electrical things at once and cause a blackout, and in a later segment when Kermit attempts to demonstrate "light" and "dark" while Grover crashes around blindly in the darkness.
Eyeglasses, monocles, sunglasses, and other spectacles are often useful not just as accessories, but as a defining part of a character's features. The eyes of Scooter and Herbert Birdsfoot are permanently attached to their glasses, while Pops' spectacles hide a pair of perpetually squinting peepers. Bunsen Honeydew and Zoot have no visible eyes at all, with their glasses essentially functioning as eyes.
Still other characters have no visible eyes whatsoever. Wendell and Boober Fraggle are key examples, with the latter's "eyes" implicitly obscured by his mop of hair and cap, in the manner of Beetle Bailey.
Simplicity and suggestion can be just as effective as the most complex eye mechanism in shaping a character's personality. Miss Piggy's carefully crafted purple lids and lashes, placed over blue pupils, suggest strength and glamour. Waldorf's age and affinity for napping are suggested by the deep set of his eyes. Janice's eyes are simply a pair of angled lashes, while the Amazing Mumford possesses nothing but a pair of bushy eyebrows.
Eyebrows often emphasise (or exaggerate) certain personality traits; aggressive Muppet monsters usually have large black eyebrows, whereas the mild-mannered Kermit doesn't have any. 
There are cases in which eyelids are built for a character who does not normally have them, or when the eyelids that they do have are modified to cover their eyeballs. This is done for scenes in which a character is required to sleep on screen, when the simpler solution of turning the eyes away from the camera will not work.
|Final Fantasy IV Enemy|
|GBA Name||Security Eye|
|DS Name||Security Eye|
The Security Eye is an enemy in the game Final Fantasy IV. Security Eye counter all attacks with the Alert ability, which summons a Stone Golem, Chimera, Naga, or Flamehound. Any attack made when an enemy is on the screen that targets the Security Eye results in a Beam, which deals Magic damage. One of each kind of Security Eye appears in various "monster-in-a-box" encounters.
Obviously, because of this creature's attack pattern, there is no real way to make it through the fight without taking any damage. Until you have finally destroyed the Security Eye, ignore the other monsters it summons, because it will just summon more. When another monster enters the fray, concentrate your attack on the Security Eye until it falls, using Rosa to heal any damage caused by its Beam counterattack. After it dies, shift your attention to the monster left behind.
A noticeable feature of the Security Eye is that it will not attack unless provoked. Because of this, the encounters with it can be a great opportunity to restore HP/MP with Rosa's Pray. Have everyone else defend and Yang use Focus twice. When you are ready, attack with Yang (with Lightning Claws equipped, if you want to expose his weakness) and it should go down in one hit without summoning any other monsters. Alternatively, you can use Ramuh with Rydia, and it should also go down in one hit, since the Security Eye itself is fairly weak. You can also use Cry without it noticing.

In most episodes, the character whose eye is shown is the character with the flashback or flashforward.
Through the use of digital effects and contact lenses, actors' eye color have been altered regularly throughout the episodes of Lost during particular scenes, usually ones related to the mythos of the show. Actor Terry O'Quinn has confirmed this in interview. [source needed]

In most species, the eye worked by directing light onto the optic nerve by means of a lens, and was protected by an eyelid designed to remove foreign objects and shade against bright lights. There were many variations, from the subtly degraded night-vision of the local Human population of Hapes, through the night-vision enhancing glowing red eyes of the Chiss, to the multi-faceted eyes of Rodians, the infrared vision of species like the Barabels, the eyes of the Ssi-ruuk with their sensitive retinae and highly-evolved eyelids, and the exotic visual perceptions of the spacegoing Oswaft.
There were also species like the Miraluka, who lost their eyes in the course of their evolution, depending instead on the Force, and the Shaper caste of the Yuuzhan Vong species, who had bred several species of highly sophisticated creatures called mqaaq'it to serve as symbiotic artificial eyes. Yuuzhan Vong had Eye sacks under their eyes.
The photosensitive cilia on the Cloak of the Nuun, another Yuuzhan Vong biot, were perhaps among the most exotic organic eyes known. Tiny membranes covering the creature's entire surface, they saw the immediate area with near-perfect accuracy from every angle, enabling the cloaker to disguise itself, chameleon-like, against its surroundings.
