A search for 'hippus eye' (two separate words, not quoted as a phrase)
turns up a bit more. The only references for its use in biometrics were
from Iridian or the scientist who is now at Iridian who developed and
patented its use for that purpose. But there are plenty of references to
'hippus', the continual motion if the iris that keeps us from
habituating to an unchanging scene and is related to eye fatigue.
Apparently it includes contraction/expansion of the iris, which would be
hard to fake with a contact lens.
