Eyes that See

I am reflecting on how eyes are often neglected parts of the body. There is an expression which reads, "The eyes are windows into a person's soul", and yet, many spiritual traditions see the eyes as something a little bit uncontrollable. In Surangama Sutra, there is even mention of an eye faculty and consciousness which can delude the mind, even controlling a person's behavior by focusing only on what is desirable. We sometimes hear the expression in English, "She or he only sees what they want to see",and this is indicative of a person whose eyes have got the better of their own judgement  and discernment. Seeing all the possible "defective" things that can happen when a person focuses on seeing, is there any validity to the idea that eyes can reflect deeper parts of each others' psyche? Can our physical eyes tell us something about our mental being?
   I don't have an answer to this question, but I do suspect that eyes can play a big part in how a person relates to others. When someone around me fails to "look me in the eye", I will tend to think that either the connection with that person is not strong enough, or they are hiding something from me on purpose, or perhaps a bit of both. The point is, eyes are ways to establish authenticity in connection. Even if I don't fully trust my senses anymore and have become cynical to the possibility of establishing validity through sense data alone, eyes can communicate a depth of understanding that two people might share. Of course, one can never really tell if someone else has fully understood us, but perhaps the point is more about the intention that eye contact communicates, and how true eye contact establishes a respect between people that is "I Thou" rather than "I It", to paraphrase Martin Buber.
