Iris The circular muscles of the <b>iris</b> expand and contract the pupil. The size of the pupil determines how much light will enter the eye, so the iris effectively controls the amount of light that is passed to the retina. The iris is also responsible for eye color (blue, brown, green, hazel). See the related link below for more information on the iris.
The iris is a flat and ring-shaped membrane behind the cornea of the eye with an adjustable circular opening in the center called a pupil. This is the structure that provides an individual with eye color. Together with the pupil, the iris is responsible for regulating the amount of light that gets into the eye.oo 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.
