Answer:
The correct answer is: Pupil.
Explanation:
- Light enters inside the side through a small opening in the iris of the eye which is called the Pupil.
- The outer most part of the eye Cornea and the outer chamber aqueous humor are both transparent and allow light to refract through them.
- The Iris, which a circular and thin comes next to the cornea and aqueous humor. It is reponsible for regulating the amount of light that can reach the retina by altering the pupil size.
- The change in the size of the pupil is mediated by muscles in the iris.
- There are two types of muscles, radial muscles and circular muscles.
- In bright light, the radial muscles of the iris relax while the circular muscles contract. This decreases the pupil size allowing less light to pass into the retina.
- In dim light, radial muscles of the iris contract while the circular muscles relax. This increases the pupil size allowing more light to pass into the retina.
