The iris is a muscle located behind the cornea of the eye. It adjusts the size of the pupil to control the amount of light entering the eye. In bright light, the iris contracts to make the pupil smaller, limiting the amount of light that reaches the retina. In low light, the iris relaxes, making the pupil larger to allow more light into the eye.
How is the Nerve impulse responsible for the pupil becoming smaller?
Pupil is a window for the light to enter our eyes. When we are in a dim light a nerve impulse is generated to the brain to enlarge the pupil. Size of pupil is managed by the iris (coloured part of the eye). If excessive light is there, the pupil shrinks to a smaller size so that the eye's not damaged esp. the retina where the image of objects are formed

How and why does your pupil change in size?
The pupil of your eye changes (growing bigger and smaller) to control light entering the eye. This allows you to see in both bright and dim light. The muscles that control the size of the pupil are called sphincter pupillae and dilator pupillae. Your pupil increases in size when there is little to no light present, and decreases in size when more light becomes available.
