Iguanas have excellent vision and are able to see shapes, shadows, colors and movement at long distances. Iguanas use their eyes to navigate through crowded forests, as well as for finding food. They use visual signals to communicate with other members of the same species. They respond to visual stimulus of colors such as orange, yellow, pink, and in rare cases blue as food substances.
