The pupil serves two important functions - to control the illumination in the eye, and to improve the optical quality of the image on the retina. The first function is obvious - the smaller the hole, the less light gets in. It therefore serves to regulate the light level within the retina. The second function is very important because as the pupil gets larger, more aberrations are created and the image on the retina gets "messier". People with no iris (aniridia) have very poor visual acuity because the eye can't get a sharp image, both because there is to much light (over-saturation) and because there are lots of optical aberrations present. One final function of the pupil is to increase depth of focus, similar to an aperture stop on a camera. This basically increases the range (distance) over which things appear sharp.
The main function of the pupil is to regulate the amount of light entering the eye. It dilates in low light conditions to allow more light in and constricts in bright light to reduce the amount of light entering the eye.
The pupil is circular opening located in the center of the iris (the colored part of the eye). It controls the amount of light that enters the eye.
It helps you see silly.
It regulates the amount of light that reaches the retina, allowing us to seeboth in strong daylight and at dusk.

The pupil is the opening in the center of the iris (the colored part of the eye) that allows light to enter the eye. By dilating or constricting, the pupil controls the amount of light reaching the retina at the back of the eye.
There is one pupil in each eye. The pupil is the opening in the center of the iris that allows light to enter the eye. Its size can change depending on the lighting conditions to regulate the amount of light entering the eye.

The color of the pupil is due to the presence of pigments in the iris of the eye. The concentration and distribution of these pigments determine the color of the pupil, which can range from light blue to dark brown. The pigments help regulate the amount of light entering the eye by adjusting the size of the pupil.
Yes, the pupil is a physical structure of the eye. It is the black circular opening in the center of the iris that regulates the amount of light entering the eye. The size of the pupil adjusts in response to lighting conditions to help maintain optimal vision.
adjusting the light entering the eye through the shrinkage and expansion of the pupil is the main function of the isris

The pupil constricts or dilates depending on how much light is available. The pupil's function is controlled by our autonomic nervous system.
The iris controls the size of the pupil. Which in turn, controls the amount of light entering the eye.
