Pupillary light reflex is autonomic.
Photopupillary reflex is pupillary constriction in response to light.
The receptor is the retina of the eye; smooth muscle of the iris is the effector. They both change simultaneously because the pupillary light reflex is contralateral.
It is Polysynaptic
The parasympathetic nervous system stimulates salivary gland secretion, and accelerates peristalsis, so, in keeping with the rest and digest functions, appropriate PNS activity mediates digestion of food and indirectly, the absorption of nutrients.

The Human Reflex Physiology Review Sheet states that "Conversely, other reflexes require the involvement of the brain, since many different inputs must be evaluated before the appropriate reflex is determined. Superficial cord reflexes and pupillary responses to light are in this category" (p. 342).
autonomic
The ciliospinal reflex and the pupillary light reflex are classified as autonomic reflexes.
pupillary light reflex is controlled by parasympathetic branch of Autonomous nervous system
The division of autonomic nervous system responsible for pupillary light reflex is the parasympathetic system. This is what causes the pupils to close down or open up in response to lighting conditions.
While pupillary size in principle is controlled both by the sympathetic and the parasympathic nervous system, the typical closure of the pupil after illumination (i.e. the pupillary light reflex) is mediated by the parasympathetic innervation of the constrictor muscle of the pupil.

It is Polysynaptic
The two are different because of what triggers the reflex. While the patella is triggered through the sense of touch, the pupillary is triggered through light.

The patellar reflex is ipsilateral. If the stimulus is applied to left knee cap, the left knee responds. On the other hand, if the right knee were to respond to a left knee stimulus, the response would be considered contralateral.
