What is "pupil"?
The pupil, a crucial part of the eye, acts as a gateway for light to enter the inner structures. It is a dynamic, adjustable opening surrounded by a colored iris. The size of the pupil is regulated by the iris muscles, which contract or dilate in response to varying light levels. In bright conditions, the pupil constricts to limit the amount of light, protecting the delicate structures of the eye. Conversely, in dim lighting, the pupil dilates to allow more light to enter, enhancing visual sensitivity. Through its adaptable nature, the pupil plays a vital role in regulating the amount of light reaching the retina, ensuring optimal vision in different environments.
