Anybody know what is in the eyes of deer
that lets them see microwaves and infrared light waves?

Research indicates that deer can probably see yellow and blue and one company would have you believe that they see ultraviolet (UV) very well.  I haven't been able to get one to tell me for sure as yet.    :D  

Infrared is supposed to be invisible to everything and I haven't heard of microwaves being visible at all.    :confused:
