Pupil (eye) The pupil is the opening in the centre of the eye. Light enters through the pupil and goes through the lens, which focuses the image on the retina. The size of the pupil is controlled by muscles. There is a circular group, which squeezes the iris smaller, and another group which pulls the iris wider. When more light is needed, the pupil is made larger. In brighter light, the pupil is made smaller. The pupil can be compared with the shutter of a camera. It is surrounded by the iris which is the coloured part of the eye. The lens changes its shape depending on how far away the eye focuses. The focus point is where the eye is focusing on. The light makes the pupil change its size.
