Question: Why and how do the pupils of your eye change size!?
Answers:
The pupils of your eyes are actually tiny holes that let in light to your eyes so you can see!. If too much light gets into your eyes it can damage them, so if there is a lot of light your pupils get smaller to let in less of it, and if there is very little light your pupils get larger to let in more light so you can see!. It is like when you go to the eye doctor and get drops in your eyes to dialate them, your pupils will not get smaller, so you have to wear those plastic sunglasses so as to not let too much light into your pupils!.Www@Answer-Health@Com

The size of the pupil is determined by the amount of light entering the eye!. If it is dark the pupil gets larger so more light enters the eye, and if it is bright then the pupil gets smaller to reduce the amount of light entering the eye!.
The size of the pupil is controlled by muscles in the iris, which is the colored part of your eye!.Www@Answer-Health@Com

in response to light or dark that it sees or senses, also in times of arousal!. The eye is like a camera lens it must zoom and zoom out when needed, but it does this by adjusting it's size!.Www@Answer-Health@Com
