Another thing to look into is FL-41 tinted glasses. I learned about them from a local vision therapist, and just ordered a prescription set about a week ago. There have been studies (e.g. [1]) indicating its usefulness for light sensitivity, migraines, and circadian disruption from using computers/TV at night. I don't have my glasses yet so I can't speak personally to their effectiveness.
