Flourescents emit a light that is green, look at your photos if they haven't been color corrected. You add magenta to get rid of it. Could this color shift - away from daylight balanced light - put some strain on the eyes/brain, etc?
Hmmmm.

Fluorescent bulbs com in 4 standard "colors" of light depending on what was cheapest at the local supply shop. I believe the strain comes from the 60hz pulsing of the light. I've heard of a few tales where strobing lights can induce headaches, nausea, stroke, etc.
Alternately, it's only older magnetic ballasts that run at 60hz. Newer electronic ballasts run anywhere from 5khz to 20khz. This would explain why some areas of fluorescent lights can trigger migraines while others not.
