“I will be 65 soon, and I never even heard of Heterochromia. Never really questioned why my eyes are the way they are”

I will be 65 soon, and I never even heard of Heterochromia until very recently!  I have Central Heterochromia,  but never really questioned why my eyes are the way they are.  I thought they might be considered hazel, but I didn’t really know, or even think about it much.
