Actually a smaller screen would be better if the stuff on the monitor caused migraines.
Flashing lights on the sides often are a cause of migraines, for example when you're driving along an alley with sun shining trough the trees onto the street every 50m or so.
Well, not in SWTOR, since a lot of the lower resolutions come in awfully blurry, and the mods in the CSR forum telling you that it is your monitor being broken or malfunctioning.
Avoiding the common causes by a professional UI team would be the best option overall. But you know, people with basic UI design knowledgedo not work for sheep.
Edit:
Oh, and @Mods: How about mentioning the migraine caused by the UI in the title of the thread?
