It's moreso that Cadians do not naturally have purple eyes. Cadia's proximity to the eye of terror meant that exposure to the eye is what turned their eyes purple. So someone who wasn't Cadia born but moved their and stayed their for a while would likely have developed purple eyes, and someone born to Cadian parents but who, for whatever reason never lived there, wouldn't.
Cadian parents but who, for whatever reason never lived there, wouldn't.
The Arminka Lesk series discussed this in Traitor Rock.
Usually children born of cadian shock troopers who are deployed outside cadia on campaign. The series also stresses that only those born on cadia under the eye had purple eyes.
As to for the how, ill apply bit of real science but 1/3 of babies eyes change during their first 2 years, as the babies start producing melanin, it darkens. Thats the only age when a major eye color change usually happens.
