Pupil dilation (also called mydriasis) is the enlargement of the size of a person's pupils under normal lighting conditions. Normally, the pupil size increases in the dark and shrinks in the light; however, a dilated pupil will remain excessively large even in a bright environment. This effect generally occurs on drugs which increase overall serotonin levels including psychedelics, MDMA, various stimulants, and some anti-depressants.
