Solution

Pupil
The amount of light reaching the retina of the eye is controlled by Pupil.
Rods and cones are two types of photoreceptors present in the retina of the eye.
In presence of bright light pupil contracts to limit the amount of light entering the eyes.
In presence of dim light, the pupils dilate to increase the amount of light entering the eyes.
