Answer 2

pupil

Explanation:

The pupil is a hole in the iris (coloured portion of the eyeball) into which light from the surroundings enters our eye. If a lot of light is coming from the surroundings, then the pupil becomes smaller to restrict the amount of light that can enter into our eye. This is because a lot of light entering our eyes can damage the retina and the eye lens.

Also, when it is very dark, the pupil becomes larger (or dilates) to let a large amount of light enter the eye. This helps us to see better in the dark.

This constriction and dilation of the pupil is controlled by the muscles attached to it known as the ciliary and radial muscles.

Therefore, the amount of light entering the eye is controlled by the pupil.
