Accommodation reflex / Pupil Reflex

Accomodation pupillary reflex , pupil reflex , accomodation reflex and pupillary light reflex are also summarized under the same topic.
It is contraction of the pupil when trying to focus on a near object and is controlled by the parasympathetic nerve fibres carried in the third cranial nerve (oculomotor nerve) from the Edinger–Westphal nucleus of the midbrain (synapse in the ciliary ganglion) which act on the sphincter pupillae muscle to cause reduction in pupil diameter and on the ciliary muscle to cause relaxation of the suspensory ligament, allowing the lens to adopt a more spherical shape for near focusing.
