Some device reads my eye, right? After that there are bits representing my
eye. Those bits can be compromised like any other bits (fill in your
favorite attack on passwords here).

After someone steals my password bits, I can create new bits to go through
this process by entering a new password. But I can't readily create new
substitute bits if the whole point of those compromised iris-based bits is
that they could be generated *only* by my eye, via some hardware that I
can't change.
