For other uses, see Iris (disambiguation) . The iris (plural: irides or irises) is a thin, circular structure in the eye, responsible for controlling the diameter and size of the pupil and thus the amount of light reaching the retina.he iris develops from the anterior two layers of an embryonic neuroectoderm structure called the optic cup. The optic cup also produces the iris sphincter and dilator muscles.
Too much or too little light can hamper vision. The muscular iris moves to shrink the pupil if there is too much light and widen it if there is not enough. This is an involuntary function, controlled by the brain. The iris is made almost entirely of connective tissue and smooth muscle fibers.Despite a common belief, actual change in color of the iris rarely happens. While the color of an eye may appear to change, this is typically due to lighting changes or perception based off nearby colors.oo much or too little light can hamper vision.
