Olive Leaf in large dose such as tea tends to drive out Herpies and Herpies likes the face, mouth and eyes, so my guess and this is a wild guess, is that she is feeling a cleansing effect and it could get worse before it gets better dependling on how much she has to get rid of. Cateracts are a form of herpies for example. Otherwise if I knew nothing, I would always suggest it was an iron problem. Normally no new iron is needed, only to use what the body already has and yellow Dock has always been the choice.
