Quote - Janal, I checked the eyes, and it seems the sclera and iris have the same settings so there is no difference in the eyes.

Thank you for this, Pokeydots and thank you for Lina and Koshini. 

Quote - EZSkin adds reflection in the sclera shader, but not in the iris shader. That's the main difference from EZSkin's point of view.

Ah, okay, so that is why I probably used sclera. Anyway, I'm pleased it is okay.
