Bagian mata yang berfungsi untuk mengendalikan diameter pupil
Correct Answer
Iris
Explanation
The iris is the part of the eye that controls the diameter of the pupil. It is a circular, colored membrane located in front of the lens. The iris contains muscles that can contract or relax, thereby adjusting the size of the pupil. This adjustment helps regulate the amount of light entering the eye. When the iris muscles contract, the pupil becomes smaller, limiting the amount of light that enters the eye. Conversely, when the iris muscles relax, the pupil becomes larger, allowing more light to enter. Therefore, the iris plays a crucial role in controlling the amount of light that reaches the retina.
