How old is your daughter? I am dealing with photophobia and the only thing (so far) that has helped are tinted lenses. Would it be possible to get a pair of children's glasses for her? That way, you don't have to control the environment she's in as much....her glasses will filter out the worst of it.

If you see an optometrist who knows how to handle light sensitivity (believe me, not all of them do...though you probably know that already) ask them about tinted lenses, rose color is what works for me as I have a problem with blue/green spectrum light. I hope this can help.
