The false acceptance rate (misidentification rate) for iris recognition is 1 in 1.2 Million.
iris recognition
Because our irises are unique, some use iris recognition as a security device.
John Daugman was the inventor of the iris recognition system.
As long as the blind person still has an iris, they could pass the iris recognition test.
Scanner
Your iris is unique, just like fingerprints, but it's much harder to copy.
It is a technology that identifies people through their eyes.
the disadvantages of iris recognition is that a person who has a colour blindness or who are blind cannot pass through this iris recognition test.the advantages is that iris is an unique organ which all the people possess.

Both of these are ways to identify a person. An iris recognition looks at eyes and finger prints look at fingers.
Depends on the system. There are methods to recognize if it is a person, if it is a high resolution picture of an iris or if a person is using a "fun" contact lenses, but the companies (that deliver iris recognition solutions) should implement these procedures on their systems. It is also possible to know if a person is using eyedrops to avoid iris capturing. Specifically about the main question I haven't read nothing about it (lenses with a pattern and I think it is too costly to produce them), but the companies should test their systems and know its vulnerabilities.
