Post scriptum,
For those OptiBuffs out there who want to play with some chromatic aberration experiments on their own eyes, here is a neat one... The Duochrome test is a good way to see how axial chromatic aberration causes some colors to be in better focus than others. However, if you observe a horizontal object or bar against a bright sky (perhaps across a window), you can experiment with the "color-fringing" of your own eye. While looking at the horizontal object, slowly raise the horizontal edge of a card or piece of paper over one of your pupils (be sure to occlude your other eye). As the card limits the light entering the eye to peripheral zones of the pupil, you will see blue and yellow color-fringing around the object.
Best regards,
Darryl
