+ Dragonfly, Adults, Eyesight: Odonata
  * Dragonflies have tremendous eyesight. Their compound eyes are very large and have up to 50,000 individual lenses. Their eyes wrap around the top of the head. Sight is by far their most important sense, used to catch flies and avoid birds.
+ Lizard, Physiology
  * Sight is very important for most lizards, both for locating prey and for communication. Many lizards have highly acute color vision. Most lizards rely heavily on body language, using specific postures, gestures and movements to define territory, resolve disputes, and entice mates. Some species of lizard also utilize bright colors, such as the iridescent patches on the belly of Sceloporus. These colors would be highly visible to predators, so are often hidden on the underside or between scales and only revealed when necessary.
+ Pictogram: Symbols
  * A 'pictograph'Gove, Philip Babcock. Webster's Third New International Dictionary of the English Language Unabridged. Today, pictograms are used very often. Because they are independent of the language, they are often used where there are people who need to understand things, even if they do not read or speak the language. Pictograms are also often used where it is important to understand something fast. Sight is faster than reading. That way, pictograms are often used for signalling in emergency situations, such as showing emergency exits.
  * The ability to interpret visible light information reaching the eyes is called 'visual perception'. Sight is the resulting perception. The components that are necessary for vision are known as the visual system.
