I have epilepsy and migraines. When you're photosensitive, your neurologist will basically give you a test where you stare into a strobe that ramps up in frequency while he watches your brainwaves.

IIRC, photosensitives have a relatively narrow band of frequencies they are sensitive to, and your doctor will tell you.

What I'd do is try several different refresh rates and see if that helps.
