  Bear in mind that when physicists look for phase differences in visible
light, they do it by using interference patterns.  Electronic devices are
too slow to measure phase any other way.  Biological systems are much
slower than electronic devices.  It is almost inconceivable that light
phase information could be detectable in the retina and associated
processing.
