I agree with the following quote: 

"It is only with one's hear that one can see clearly. What is essential is invisible to the eye" (Antoine de Saint-Exupery). 

Because I think our eyes are see what we want and we can make it on the bad or a good way. For example when we love some one we can't see the bad thing , we believe she or he is perfect ! Love is blind and finally as what they said the ear loves before the eye sometimes.
