Yeah. I too believe in that the eyes says all about a person. I too have seen a lot in others eyes. My ex girlfriend said to me "Stop looking at me like a dog". I just have looked at her for 3 seconds. This and some other things make me believe that the eyes often tell the truth. But it is like BobbyT says...some are better at hiding it then others. Some can even lie with their eyes.

My eyes are sometimes a dishwater blue and sometimes a bright green. I have noticed that when people look at me they often smile or it comes naturally, but on occasion I have been places like shopping malls where people seem to get shaky around me. It's been happening for awhile that I've noticed that people get edgy when they are around me and it sort of bothers me because there's no big reason for them to be so outright...like it makes me feel like a total freak.

I think your eyes do tell stories. I have trouble looking people directly in the eyes because I end up staring too hard and getting awkward. But then it's hard not to. But especially when I'm feeling great and then people are like "ewww" she's weird. 

 
Well, it seems I may be alone here. I don't look people in the eye. Maybe briefly when talking to them just to be polite or to test myself and see how long I can, but I really hate looking into people's eyes. It makes me uncomfortable. Especially people who stare back into mine.

So I can't say if there is a difference or not because I avoid the whole thing.

Eyes have always been a big thing in my family, because both mine and my mother's eyes change colors, drastically.  It was always a family joke and I just assumed that it was normal.  Of course when you start going to school and other children are looking at you...you quickly learn just how 'abnormal' you really are.

Adults, especially ones that have a very rigid box and do not step out of it, tend not to even notice.  It's as if they force themselves to believe it doesn't happen.  For more open-minded people I will inevitably at one time or another get "Do you know your eyes change colors?"  To which I smile and reply,  "Yes, I'm well aware."

It's a direct result of mood and thought processes.  My eyes are naturally a sky blue, but if I'm feeling mischievous they'll turn sharp dragon green.  If I'm thoughtful or sad, they'll turn a smoky gray.  Every shade of blue under the sun depending upon the intensity of what I'm thinking or feeling, all the way to violet. 

Now, in my quest for normalcy over the years, I've attempted to explain it in the form of blood pressure and the amount of blood pumping through the back of the eye shining through light irises.  That's such BS...but you wouldn't believe the amount of people that believe stuff like that.

Now on to the gaze in general.  When I am surrounded in women of power, I am told that my gaze is over-confident and piercing.  Basically if someone fears I may usurp them...I'm intimidating.  Mind you, this does not happen the same way entirely with men.  When I am around men of power who meet my gaze, they see me either as flirtatious or b.itchy.  This also a direct result of their own self-esteem.  If they think I'm flirting with them...probably are pretty confident in themselves, if I'm a witch who needs to find her place...then clearly they think they have something to lose to me.

 If I'm doing a public speech or playing a roll, I'm told that my eyes are expressive and captivating.  I've been told on numerous occasions that I can make the most boring materials seem interesting.  When I speak people stare straight at my face and tend not to look away...if I'm making any sort of effort to keep their attention that is.

I gauge my eye contact itself on the other person.  I know how much someone needs upon first meeting them.  I meet gazes when they need to be met and let my eyes drift when someone needs a break from me.  I have been told that I am intense but most agree that my eyes are inviting.  There is absolutely no judgment in my stare and people have commented that my eyes are 'soothing' for the most part.

I do think that 'different' people have something very different in their eyes.  The idea of 'old soul' is not lost on me.  I know exactly what you're talking about.  I've pointed that out to a dear friend of mine and he said he never really thought about it.  He has the type of intense almost judgmental and old stare.  His eyes also change from deep almost black to a more light milk chocolate or almond color depending upon what he's doing or what he's trying to convey.  I pointed out to him the differences in his eyes when he looked at me and said..."Are your eyes GREEN tonight!?"

The eyes are definitely the "windows to the soul."  They're one of my greatest allies in trying to help someone.  Through the eyes I can draw out what people need to look at for themselves.  I guess in that way I am blessed.  Being what I am gives me a special insight into people and how to help them help themselves.  It's all in what you focus on...
