Can you help me plan a simple experiment to make a basic observation of the iris reflex?
using a light torch, shine it into a persons eye and observe how the iris reflexes. To see how both irises reflex simultaneously, place a paper in between the persons eyes, and shine the light in the left eye. obeserve how the right eye reflexes, although the stimuli was not on it!
