What is the opening in the middle of the iris that controls the amount of light entering the eye is called?
PUPIL. It automatically becomes smaller due to contraction of Circular muscles via action of Parasympathetic nerve fibers, if light is more. And becomes bigger in size, if light is less due to contraction of the Radial muscles, via Sympathetic nerve fibers. This happens in order to protect Retina from excessive light. When there is total Solar eclipse and you go on looking at Sun, pupil will not contract and Retina gets excessive radiation from the surrounding of Sun and there by burning Retina, with permanent damage to it, causing total blindness.
