The iris, which works much like the aperture of a camera, expands in darkness to let more light into the pupil and contracts in bright light to keep the light-sensitive cells from being overwhelmed.

Vision is the special sense of sight that is based on the transduction of light stimuli received through the eyes.The eyes are located within either orbit in the skull. In the centuries since, doctors and anatomists have discovered that vision relies on just the opposite effect. We use our vision in almost every activity, so the eye is a most important organ.

Human Anatomy and Physiology Pdf Review: Over the years, there have been many textbooks which have been released by several authors on the subject of human anatomy. This part of the human eye, the sclera, is made up of fi brous tissue and provides a tough protective coating around the whole eyeball. The bony orbits surround the eyeballs, protecting them and anchoring the soft tissues of the eye (Figure 1). In Herophilus’ day, scientists believed that we could see because beams of light came out of our eyes and fi xed on objects. The colour of the iris comes from melanin, a substance that protects the eye from absorbing strong light.
