Plus, what about peeps that have migranes brought on by fluorescent light bulbs?
Not sure this relates to compact fluorescent light-bulbs - they run at kHz. Strip lighting - for sure. They have a flicker at 100 Hz (120 in the US) and the eye tries to follow this by tensing the muscles that alter focus and the Iris aperture. Which makes for tension and migraine in some people. Most of the problem is peripheral vision - it is faster if less precise than central vision. We have evolved to notice movement (hence intensity variations) out of the corner of our eyes because that might be food or death. Either way - more peripheral acuity results in better survival for the person and their genes.

If the CFL bulb is dying slowly it can flicker noticeably but then you will literally THROW it out.
