Your pupil gets smaller and larger depending on the amount of light present. in a dark room, your pupil will get big to collect as much light as possible, so that you can see. When you look at the sun or a bright object (which you shouldn't) your pupils get smaller because they have too much light.
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
The dilator muscle which makes the pupil larger and the constrictor muscle which makes the pupil smaller.
With high intensity light your pupil constricts. This happens to protect your retina from damage by light of high intensity.
your eye would explode
