Is the response of your pupil a reflex or a voluntary action?
The constriction of pupils in response to bright light is called the pupillary light reflex. If the light is shining directly into one eye, then the pupil in that eye will constrict (a direct response), but so will the pupil in the non-illuminated eye (a consensual response).This reflex involves two cranial nerves: the optic nerve, which senses the light, and the oculomotor nerve, which constricts both pupils. It is considered involuntary since you don't think about it.
What are your pupils?
Pupils are the small, dark circular openings in the center of the iris that allow light to enter the eye. They regulate the amount of light entering the eye by adjusting their size in response to the brightness of the environment.
Why do your pupils constrict?
Pupils constrict in response to bright light to reduce the amount of light entering the eye and protect the sensitive retina from potential damage. Conversely, pupils dilate in dim lighting conditions to allow more light into the eye for improved vision in low-light environments.
Why pupils have turned black in a teenage girl?
The pupil is the innermost circle in the eye. It should always be black, regardless of the person's eye color. The pupils can increase or decrease in size depending on how much light. Pupils can also change in response to the effects of medications or street drugs.Here are two videos. In the first, a doctor explains why drops dilate the pupils for eye exams. In the second, you can see a close-up of someone shining light onto a person's pupils and removing the light.

What cranial nerve controls the response of the illuminated eye?
If the light is shining directly into one eye, then the pupil in that eye will constrict (a direct response), but so will the pupil in the non-illuminated eye (a consensual response). This reflex involves two cranial nerves: the optic nerve, which senses the light, and the oculomotor nerve, which constricts both pupils.
