1.	State the functions of Iris and Pupil of the human eye (3 Marks)
Answer» PupilThe pupil is essentially a hole in the center of your iris that controls how much light enters the eye. It's size is controlled by the relaxing and contracting of the iris. When there is high light intensity, the pupil shrinks while it grows in low light intensity. This is to ensure there is enough light for vision without damaging the sensitive retina. Theirisis a ring-shaped membrane inside the eye that surrounds an openingin thecenter, called thepupil.
