Why are my pupils so naturally large? The pupil size is closely regulated by muscles in the iris. They expand and contract constantly to allow a certain amount of light into the eye. Certain conditions and medications can alter the function of these muscles and lead to abnormally dilated or constricted pupils. In absence of these causative factors, a patient's normal pupillary size can range between 2mm and 8mm in size.

Pupil Certain drugs cause constriction of the pupils, such as alcohol and opioids. Other drugs, such as atropine, LSD, MDMA, mescaline, psilocybin mushrooms, cocaine and amphetamines may cause pupil dilation. Another term for the constriction of the pupil is miosis.Substances that cause miosis are described as miotic.he pupil is a hole located in the center of the iris of the eye that allows light to strike the retina. It appears black because light rays entering the pupil are either absorbed by the tissues inside the eye directly, or absorbed after diffuse reflections within the eye that mostly miss exiting the narrow pupil.
