Quote - I have a question about the cornea mapping. If I apply the same trans map to both corneas, one gets reversed.  Eyes don't have reversed reflections. Was the mapping done like that for a reason?

Yes, it was. For any asymmetric cornea effect I can think of except baked in reflections, it seems more intuitive to flip it if the same material is applied to both eyes unchanged. And baking in reflections is a bad idea, anyway. But you can always create a second material with a flipped map if you don't like that default behaviour.
