Try going to an eye doctor. I have tinted computer glasses I bought from Amazon.com, and I swear it helps decrease the pain. I'm due for an eye exam and wear transition lenses, so I'm going to ask for prescription computer glasses with the blue light blocking tint. For sunglasses, try Suncloud. I bought the darkest pair they offered and it does help for when I have a migraine at work.
Just being in the bright room make my head ache.
I loved the official fl-41 tint, but the blue light filter offered on zenni is almost as good. Insurance didn't touch my tint so it was $150 out of pocket for the fl-41. Zenni had I think a $10 up charge.
