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.

The round pupil in a lizard is generally better adapted for diurnal species whereas slit pupils are found in nocturnal species. Most lizards can see in color and some have opsin proteins which allow them to see in ultraviolet wavelengths that the human eye cannot perceive.
