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 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.

Well I've seen a lot of letters and it seems to me
There's something real special 'bout the letter 'Z'
But boy we're sick of singing 'bout zippers and zoos
There ain't enough 'Z' words
Got the ZZ Blues
You can stick with 'zebra' 'cause it's tried and true
Maybe mention 'zither' just for something new
But once you've shown them 'zebra', 'zither', 'zippers' and 'zoos'
You're almost out of 'Z' words
Got the ZZ Blues
Time to write a song about Zanzibar
C'mon and sing along about Zanibar
Guess I could be wrong about Zanzibar
Going zingy with the ZZ Blues
We're zooming back to zipper 'cause it's still the best
Zipping back to zebra and we need a rest
Gettin' tired of thinking
Yeah we've paid our dues
There ain't enough Z words
Got the ZZ Blues
(band starts falling asleep while still rocking!)
Only band I ever worked with to fall asleep and keep playing the blues!
Guess I might as well join 'em
and cop some Zs myself!
(ends with band asleep but the music still going!)
