PuffyCloud I agree that there might be health consequences of flicker exposure over prolonged time, and that vision degeneration with aging might be caused by this. However that still does not explain why people like us also have headaches.
Yes we may be special in a way that we notice this compared to other people, but my vision is not perfect, I wear glasses, although corrected for right eye only. So we may also be people with neurological problems who get migraines from flickering light and certain wavelengths of LEDs, or both. Ideal solution is then to try to solve for your health, why also paying attention to the tech side, because there is a very large possibility that the lighting tech today is badly quality controlled.
The tool you posted is nice, but does not seem to show all that much. I started another thread here some time ago where its explained how to build your own oscope for cheaper than usual, and that might give more precise readings.
Ive contacted lightaware.org, theyre interested in me and maybe we could all do that and write them our stories, and make them and their influence grow.
