I have/had inflammatory bowel disease, around five years ago I realised through extensive food diaries that red meat/dairy was a factor. I cut out these foods, for the first year whilst my bowel disease improved dramatically, my screen induced migraines worsened. However, every year since my migraines have improved. I'm not sure if I am cured yet, but I haven't experienced any problems with screens or software in six months but I've been cautious.
When I'm sure I'm cured I'll write a big post outlining what I think the causes were, quoting scientific journal papers etc, but I don't know how much help it will be to regular forum users. This cause could be unique to me.
