Hi again, well I've been doing some reading and it seems there are loads of people like me, they even do tests on us!  Can't thank you enough for giving it a name, I've searched before but not really had a target to look for.  Theres lots of sites with more information, this is the first I read and it summarises quite well:

I have 20/40 vision in my right eye, 20/200 in my left eye.  I can cover one eye(with or without glasses) and perceive a slight difference in hue looking at the same object.  

Explanation... Lenses refract light.  Light of different wavelengths(colors) propagate through a medium at different speeds based upon the medium's index of refraction.  Since one of the corneas of my eye is thicker than the other colors are ever so slightly delayed by their wavelength and arrive at the retina at different times.  Corrective lenses cannot fully correct this effect.

This same effect is what causes prismatic effect looking through a telescope or causes stars to twinkle.  Colors appear to split into their component colors.  Although I see no prism effect the perceived overall hue of the image is slightly affected.

My right eye does 90% of the work processing detail because from birth that eye had a sharper image and became my dominant eye.  The left eye was fuzzy and therefore in most cases it's image is ignored.

One of the coolest days of my life was getting glasses and finding out that stars were pinpoints, not dandilion-like puffballs, and that you could actually "SEE" individual leaves on trees and see powerlines from over a mile.

But I notived the color difference very early on.  BTW, at close(6" to 2') range, my left eye is capable of seeing much finer details and at lower light levels than my right.  Comes in handy when trying to discern a tiny number on a dimly lit IC chip inside a PC from an extreme angle.  Shame it only works up to 2'.

Welcome s_firestone - it's nice to hear from you.

Interesting differences.  I wonder if your left eye is dominant at close range because it is nearsighted and thus gives better images up close while your right is better at distance.  

The difference in hue is strange.  I've never heard of that before, not that I'm in any position to hear much of those sort of things.

Hi, I didnt know I had a sight problem till I was around 10.  When I got glasses the world seemed alot more vibrant and I had the same sort of thing.  Clouds was my first wonder!  Later I got contact lenses and yet again the difference was intense.  The colors I see for things dont change though no matter which form of sight I use (none, glasses, contacts).

Tann - I'm delighted that you turned up and gave such a clear description of synaesthesia, proving that I was not talking clap-trap above ! In answer to your comment about what people actually experience the answer is that it seems to be quite individual. Some people experience colours triggered by specific words or situations, others 'taste' shapes - in other words they experience a taste sensation when the see certain shapes. I think it must be a wonderful experience to have because it adds another dimension to the world as we experience it with our limited senses.

Stephen - I was about 6 when I first noticed that with one eye the fluorescent light in my classroom looked a creamier colour than with the other eye, which made it look stark white. I have since found quite a few people with this sort of mild disparity in colour perception between the 2 eyes. Initially I thought it might have something to do with retinal photoreceptors. I must admit I am intrigued by your suggested answer - which I have not heard before.

Maybe all these people who see auras are really just experiencing synaesthesia, but then, the color they see tells them something about the person.  I guess there has to be some ESP involved in the brains choice of color for the individual.

I don' think that it is a form of ESP. I thin that it is probably yhe fact thet certain colors like red automatically suggest evil where as blue may suggest calm or nice. Now i do not know that much about ESP so hat could be what i just described but i am not sre. I have a very small amout of synaesthesia. I had neverr realy though about it untill i looked at this site.
