The consensual reflex of the pupil is the simultaneous constriction of the pupil in both eyes when light is shone into one eye. This reflex is controlled by the autonomic nervous system to regulate the amount of light entering the eye and protect the retina.

Reflexes such as blinking and pupil reflex are centered in the brainstem. The trigeminal nerve is responsible for the blinking reflex, while the pupillary reflex is controlled by the oculomotor nerve. These reflexes help protect the eyes from harm and regulate the amount of light entering the eye.
The pupil dilates when stimulated by the pinching on the nape of the neck.
The term is "pupillary light reflex." This reflex causes the pupil to constrict in response to a bright light stimulus, which helps protect the retina from excessive light exposure.
The pupil shrinking reflex protects the eye by reducing the amount of light entering the eye in response to bright light conditions. This helps to prevent excessive light exposure and potential damage to the sensitive tissues in the eye, such as the retina.
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.
The pupil reflex, specifically the pupillary light reflex, involves coordination between the optic nerve (cranial nerve II) and the oculomotor nerve (cranial nerve III). When light is shone in one eye, the optic nerve transmits signals to the brain, which then sends motor signals through the oculomotor nerve to constrict the pupil of both the illuminated eye and the other eye (consensual reflex). This reflex helps regulate the amount of light entering the eye and protects the retina from excessive illumination.
When you switch on a lamp, the brightness in the environment increases, causing the pupil of the eye to constrict, or get smaller. This response, known as the pupillary light reflex, helps regulate the amount of light entering the eye to protect the retina from excessive brightness. The constriction of the pupil improves visual acuity in well-lit conditions by reducing the scattering of light.
The stimulus in the pupil reflex would be light
Reflex to protect your eye.
The reflex in the eye helps to maintain homeostasis by regulating the amount of light that enters the eye. This reflex adjusts the size of the pupil in response to changes in light intensity, ensuring that the appropriate amount of light reaches the retina for optimal vision.
