The following information was obtained from this eyesign book, "Real Eyesign" written by Rob Woolliss.  The book includes no less than 30 full colour eyesign photographs and can be obtained from 'Choice Publications'.

THE PUPIL:  In all instances and without exception it must be jet black in colour, most perfectly shaped (round), any degree of misshape is totally unacceptable and would render the pigeon of no use to us. The pupil must neither be too large nor too small, it must however marry-up in harmony with the other circles.

THE COLOUR CIRCLE:  This is the second circle that we should take into account when assessing the pigeons quality by using its eyesign as a guide. It comes In a multitude of colours, all of which are equal to each other with the exception of the metallic variety, as these are most suited for breeding purposes, the many times I have heard pigeon fanciers going on about a "supereye" which they have in the loft, shouting it's praises from the roof tops, it's something to behold the much coveted "green", believe me this line of thought is not only very foolish, it's also a myth, pigeons breed winners with all coloured eyes and pigeons win races with all coloured eyes.  The point I am making is that you should not put any greater importance on a pigeon because of the eye colour alone, that is not what eyesign all about.  I personally do like to see a good wide clear colour circle in the eye of a sprinter or one destined only for the short races and for the long distance candidates an even wider colour circle running right out into the iris.

THE CIRCLE OF ADAPIION:  This is the main circle of all five from which we can see breeding and/or racing potential.  Again this circle comes in different shades (varients of black) from a pale light grey to dense black, and this circle masks or sits on top of the colour circle, it is made up of varying depths of dark pigment (composition) and it is in this circle that we seek to find the "inner-rings" breeding lines to a greater or lesser degree.  I will explain myself clearer on this point, what we are looking for are fine lines in circles or fragments of circles within the adaption circle itself.  The more clearly defined are the inner-rings, then far greater is the pigeons breeding potential, we must not forget serrations while dealing with this circle, as they to are all important, again the more heavily serrated is this circles outer edge, the greater once more will be the pigeons breeding potential, a really heavily serrated circle looks somewhat like the blade of a circular saw, very ragged.

THE IRIS:  This my friends, is in my opinion the most important circle of them all, and once again it comes in all different shades, mostly variants of red, I like the bright fiery pillar-box red iris colouration for land racng, and the deep dark liver-red iris colouration for overseas racing.  Another couple of interesting points to note, for sprint racing the iris does not need to be especially granulated or mountain-ranged, but for the long distance, and even more breeding, they so do need an abundance of both, whatever the base colour of the iris, it must be rich and bright, in fact sparkling, any weakness or dilution of pigment is not acceptable and we have no room for pigeons which carry weak or defective iris's, this is the first thing that hits you when you look into a pigeons eye, if it lacks depth and lustre, then I do not want it and neither should you.

THE OUTER CIRCLE:  This is the last circle of the eyesign, the one which makes the picture complete, as it's name suggests, it appears right on the outer edge of the eye, in some cases it may be hidden by the eyecere itself, contrary to popular belief, not all pigeons carry this circle, but be sure the very best ones do, both champion racers and champion producers have it in abundance and the more pronounced it is, the better this circle increases the pigeons potential for either racing or breeding, I suppose it's an indication of supremacy and this top attribute has been either overlooked or ignored by many eyesign experts over the years.  I have documented proof that the majority of top class pigeons carry the outer circle, it must come from the outside in to connect up to the colour circle, this is what I term marrying up the complete full eye.  Another point which I must make to do with the outer circle, is that of it's colour, it will be one of only two colours and they will firstly be the same shade as the No.2 colour circle and secondly having the same shade as the No.3 the circle of adaption, never underestimate the value of this circle.
