Just as a fingerprint is bio-identifiable and unique to every person, there are two parts of the eye that are used in bio-identification due to their absolute individualism. An iris may look a similar blue or brown but on closer inspection, it is truly individual. It is the folds and crypts and freckles - not colour - that define a unique iris. Everyone's iris pattern in different. At the back of the eye, it is the pattern of blood vessels across the retina is also a unique. For some secure environments, this vessel pattern is matched to a library image of your eye for positive identification - no longer just science fiction!
