Sitting at a computer screen seems to cause symptom flares. Someone told me it is the subtle flickering that CRT computer screens have. I also noticed that most LCD screens are backlit with fluorescent lights, and I know fluorescent lights flicker too. But I just read about some new LCD screens that are backlit with LED lights. They are sometimes called "Bright" screens or "WLED" screens. And I don't think LED lights flicker. Anyone know about this? Any thoughts on whether this might reduce symptom flares.
