I teach Special Education. For some kids it is the sharp contrast of black type on white paper. You can try having her read with a piece of colored overlay over the text. Different kids respond to different colors. Most like yellow or blue. I have bought the colored plastic sheets that you can slip papers in. They often come in different colors. I have seen examples of how the text appears to move black on white with flourescent lighting. It would be difficult if not impossible to read. I had one student who got a cheap pair of rose tinted sunglasses that worked. It is worth a try. There are expensive things that can also be purchased that look more official.
