Eye

Eyes are the organs of vision. They detect light and convert it into electro-chemical impulses in neurons. In higher organisms, the eye is a complex optical system which collects light from the surrounding environment, regulates its intensity through a diaphragm, focuses it through an adjustable assembly of lenses to form an image, converts this image into a set of electrical signals, and transmits these signals to the brain through complex neural pathways that connect the eye via the optic nerve to the visual cortex and other areas of the brain. Eyes with resolving power have come in ten fundamentally different forms, and 96% of animal species possess a complex optical system. Image-resolving eyes are present in molluscs, chordates and arthropods.

The simplest "eyes", such as those in microorganisms, do nothing but detect whether the surroundings are light or dark, which is sufficient for the entrainment of circadian rhythms. From more complex eyes, retinal photosensitive ganglion cells send signals along the retinohypothalamic tract to the suprachiasmatic nuclei to effect circadian adjustment and to the pretectal area to control the pupillary light reflex.

Eyes (TV series)

Eyes is an ABC television series starring Tim Daly as Harlan Judd. Eyes follows the firm of Judd Risk Management which uses marginally legal means to investigate individuals and crimes where law enforcement would fall short. With the help of high-tech gadgets, Harlan Judd and his employees recover money for victims as well as investigate individuals for clients but still manage to keep plenty of secrets from one another.

In May 2005, having rescheduled the sixth episode twice, ABC announced that they would not be airing the remaining episodes until June at the earliest. They later announced that it would not be picked up for a second season and that the remaining episodes would remain unaired.

New Zealand television station TV2 picked up this show and aired the complete series, all twelve episodes, in the second half of 2005. These episodes appeared online via BitTorrent soon after. The show was also partially aired on Singapore television station Mediacorp Channel 5, with the pilot episode and episodes #106 to #112 being skipped. Episode #111 ("Burglary") was an exception, and was aired as the fifth episode. The show was also aired in full on France cable television station Canal Jimmy in 2006. In the beginning of 2008 the show was aired in full on Polish television station TVN 7. The series was shown on the Nine Network in Australia in 2007.

Eyes (video game)

Eyes is an arcade game released in 1982 by Rock-Ola.

Gameplay

The player controls a hat-wearing eyeball in a maze. As in Pac-Man the goal is to collect all of the dots to advance to next level, but in Eyes you shoot the dots rather than eat them. Computer-controlled eyes chase and shoot at the player. Shooting a computer eye gives points and removes it from the level, but it will reappear a short time later. Being shot by a computer eye is fatal.

As the game progresses, more computer eyes are added to levels and they take less time to shoot at the player. They also move faster.

Eyes (Donna Summer song)

"Eyes" is the third and final single from the album Cats Without Claws by Donna Summer. Edited in length from the original version on the album and remixed by John "Jellybean" Benitez, the single peaked at #97 for one week in the UK Singles Chart.

A remix of the calypso-ish "I'm Free" from the Cats Without Claws album was included on the B-side of the UK release of the "Eyes" 12" single. "I'm Free" was performed by Donna and her back-up band on a Dick Clark's American Bandstand 1984 Christmas special, and Soul Train, indicating that the song had originally been intended to be the next single.

Eyes Galaxies

The Eyes Galaxies (NGC 4435-NGC 4438, also known as Arp 120) are a pair of galaxies about 52 million light-years away in the constellation Virgo. This galaxy takes its name from its ring structure which made it popular.

NGC 4435

NGC 4435 is a barred lenticular galaxy with a relatively young (age of 190 million years) stellar population on its central regions that has been discovered by the Spitzer Space Telescope and whose origin may be the interaction with NGC 4438. It also has a long tidal tail possibly caused by the interaction with the mentioned galaxy; however other studies suggest that tail is actually a galactic cirrus in the Milky Way totally unrelated to NGC 4435.

NGC 4438

NGC 4438 is the most curious interacting galaxy in the Virgo Cluster, due to the uncertainty surrounding the energy mechanism that heats the nuclear source; this energy mechanism may be a starburst region, or a black hole powered active galactic nucleus (AGN). Both of the hypotheses are still being investigated.
