Alexandria’s Genesis is believed to be a rare medical condition which is a result of genetic mutation.

Whenever someone is born with Alexandria's Genesis, their eyes are blue or grey at birth. After six months, the eyes start to change in their first colour to purple, and this procedure lasts half an hour. During puberty, the colour deepens to a dim purple, a purple, a royal purple, pink, or purple-blue colour and stays that way. It doesn't influence the individual's vision.
