	Iris

	Re: What triggers dark spots on the eye iris?
		Iris nevi are similar to freckles found on your skin but do not grow or change color and completely benign.
		But in some conditions like Fuch's heterochromic iridocyclitis, one iris is a different color than the other and is often associated with glaucoma and iritis in the lighter iris.
		On the other hand, tumors of the iris are usually dark masses that can definitely change the color of your iris.

	Colored contact lens and methods of making the same - Patent 5018849
		The iris portion reduces or otherwise alters the reflection color of the eye and mimics the structure of the natural iris so that the tinted color becomes the dominant color when the lens is worn.
		Furthermore, untinted lenses with their respective masked iris portions may be provided to the practitioner, who then may color the lenses as desired at the point of final sale.
		The iris masking section 28 is preferably circular in shape and is positioned in such a manner as to cover the natural iris of the eye of the wearer when the pupil portion 12 of the lens 10 is over the pupil.

	The Genetics of Human Eye Color
		The exact color of the human eye is determined by the amount of a single pigment called melanin that is present in the iris of the eye.
		In basic terms, eye color is determined by the amount of a pigment called melanin that is in the iris of the eye.
		Eye color genes, through the enzymes they produce, direct the amount and placement of melanin in the iris.

	Gross Anatomy of the Eye
		Eye color, or more correctly, iris color is due to variable amounts of eumelanin (brown/black melanins) and pheomelanin (red/yellow melanins) produced by melanocytes.
		A colored circular muscle, the iris, which is beautifully pigmented giving us our eye's color (the central aperture of the iris is the pupil).
		Three chambers of fluid: Anterior chamber (between cornea and iris), Posterior chamber (between iris, zonule fibers and lens) and the Vitreous chamber (between the lens and the retina).

	Iris (anatomy) - Wikipedia, the free encyclopedia
		Heterochromia (also known as a heterochromia iridis or heterochromia iridium) is an ocular condition in which one iris is a different color from the other iris (complete heterochromia), or where the part of one iris is a different color from the remainder (partial heterochromia or sectoral heterochromia).
		The iris is an annulus (or flattened ring) consisting of pigmented fibrovascular tissue known as a stroma.
		Just in front of the root of the iris is the region through which the aqueous humour constantly drains out of the eye, with the result that diseases of the iris often have important effects on intraocular pressure, and indirectly on vision.

	Iris (anatomy) - Wikipedia, the free encyclopedia
		Iris color is a highly complex phenomenon consisting of the combined effects of texture, pigmentation, fibrous tissue and blood vessels within the iris stroma, which together make up an individual's epigenetic constitution.
		Raman scattering, and constructive interference, as in the feathers of birds, do not contribute to the color of the human eye, but interference phenomena are important in the brilliantly colored iris pigment cells (iridophores) in many animals.

		Infinitely variable in size and color, the iris blooms in slow profusion, meandering through the color spectrum, spring to fall, sea level to mountain shoulder, blooming in garden trash in a vacant lot and also blooming in the great immaculately tended beds of the stateliest gardens.
		In the wild, this uncommon iris is found primarily in shady places in the yellow-pine forests of Del Norte County, California, and in southwestern Oregon.
		This species of wild iris is found in at least 18 counties in California, on both sides of the Central Valley.

		The folks at IRIS Graphics thought we were out of our minds for buying the finest digital color printer in the world ($126,000 in 1989) and then using it to output B&W. Our first attempts involved creating a set of 4 black inks of increasing density.
		IRIS never considered their technology to have any implications outside of the proofing world and had offered us very little technical assistance in solving the many ink and paper problems we faced over the years.
		The IRIS software allowed us to add a tone to the black as well as a tint to the white areas of the final image so we were able create custom B&W profiles to meet the individual needs of our clients.

		This vast array of colors lends meaning to its name, which in Greek means "rainbow." In Greek mythology, Iris was the goddess of the rainbow and a messenger from the gods to humankind.
		According to the "New World Dictionary of the English Language," the iris of the eye is defined as "the round, pigmented membrane surrounding the pupil to regulate the amount of light." Even though we classify the color of our eyes in very general categories, each individual has his own unique variation.
		All of God's people were created with eye color.

	Bergen County Camera - Digital Camera Color - Gamut
		In the case of our deep purple Iris flowers the closest color happens to be a shade of blue.
		If the object your taking a picture of has a color that lies outside the GAMUT of your camera, your camera automatically chooses a color that is close which lies inside the triangle.
		Your camera is sensitive to a range of colors called the gamut.

	Howstuffworks "How Vision Works"
		The color of the iris is determined by the color of the connective tissue and pigment cells.
		The iris has two muscles: The dilator muscle makes the iris smaller and therefore the pupil larger, allowing more light into the eye; the sphincter muscle makes the iris larger and the pupil smaller, allowing less light into the eye.
		The aqueous humor is divided into two sections called the anterior chamber (in front of the iris) and the posterior chamber (behind the iris).

	Iris Pigmentation
		The two primary macroscopic physical attributes of the iris as recorded photographically are color and elevation (along with the shape and size of the pupil and iris angle as inner and outer boundary curves delimiting the region being modeled).
		The return signal is leading to the formation of color spots as a narrow shield in the iris region (which may or may not have a circumscribed boundary), a defense mechanism designed to attenuate the spurious unwanted signals.
		In iris analysis the reflex mapping is used in a diagnostic or interpretive mode, with the basis being that there is a correspondence between the specific features of the iris and the referred regions of the body.

	The Mavens' Word of the Day
		The iris of the eye is, as we all know, the colored part around the pupil.
		This also leads us directly to Iris, the flower, normally associated with the color violet (a color of the rainbow), but with an array of other colors as well.
		But what's important, as the Manual of Ophthalmic Terminology states, is that the iris is so named "because of the beautiful and abundant colors that were present, particularly in the irises of animals and birds." That's the rainbow connection.

	Iris scan - Wikipedia, the free encyclopedia
		Changes in the health of an individual can affect the color of the irides.
		While iris scans are said to be more accurate than most genetic fingerprinting, the golden standard of dermatoglyphic fingerprinting, established in the early 1820s by the Czech physiologist Jan Evangelista Purkyně has yet to be matched.
		An iris scan is one of the most currently used methods of biometric authentication.

		The color of the iris is produced by the reflection of light from dark pigment cells underlying a translucent tissue, and is therefore determined by the amount of the pigment and its distribution throughout the texture of the iris.
		The posterior surface of the iris is of a deep purple tint, being covered by two layers of pigmented columnar epithelium, continuous at the periphery of the iris with the pars ciliaris retinæ.
		The nerves of the choroid and iris are the long and short ciliary; the former being branches of the nasociliary nerve, the latter of the ciliary ganglion.

	Iridology FAQ
		To advance the state of the art, a baseline study of iris color and texture is needed, then a study of correlations between iris structure and health predispositions.
		The correlation between amount of iris pigmentation and age, as shown by Velchover, et al., is a good example of a well-designed epidemiological study.
		Whether the iris structure may change during a person's life in response to functional changes in organ status is a separate and further issue which presupposes the primary structural correspondence.
