HI Dawn, I had the same problem with my computer screen also, I think it's to do with your inner toxicity reacting with whatever comes off the screen itself.

I had to get a protective shield to put across teh screen to cut down or block most of those rays coming off it. It helped. Though I stick to a small screen and angle it downwards so it's not angeled right up at my face.

Also, even with all that, though it helps, if I'm not on the candida diet, it will worsen regardless. But I tried taking the shield off my computer to see what would happen and within days the reaction was absolutely severe. So I put it back on and it abated again.
