Eyes in Aura

While reading "Aura" I thought it was interesting how Felipe described the characters' eyes.  He begins with describing Consuelo's eyes as, "clear, liquid, enormous, almost the same color as the yellowish whites around them, so that only the black dots of the pupils mar that clarity."  Next, he describes Aura's eyes as, "sea green and that they surge, break to foam, grow calm again, then surge again like a wave...offering you a landscape that only you can see and desire."  Lastly, he describes his own eyes, but he only mentions that they are black.  Looking into someone's eyes can arouse emotion and start a sense of nonverbal communication.  Felipe immediately becomes entranced with Aura's eyes because of the life he sees in them.  Both Felipe and Consuelo's eyes are dull and lacking emotion or depth.  It is strange that Aura's eyes are the only ones that seem to have life and vibrant color because she is not even real, she is just a creation of Consuelo.  Eyes are sometimes considered "windows of the soul."  If Consuelo and Felipe both have dead eyes and Aura's have life, how is it that they are real and she is not?  It gives an altered sense of reality.
