This chapter is organized as follows: we start with a brief introduction to the eye and the iris. It is important to stop to see what we are measuring and try to understand from the anatomical organ what we can expect to happen with time. Following this, we will briefly describe the different components which form an iris biometric system as well as each component's functionality. This will help us to understand how age influences each part of the system. After all these basic concepts, we will move to the studies developed by different researchers on this topic, observing that different researchers have focused their efforts on different parts of the iris biometric system.
