K-Moss I don’t think of my experience as the most extreme. I’m grateful not to be amongst those who experience seizures or whose health is otherwise more severely affected than mine. My health has certainly worsened with each new LED/screen injury and I’ve taken on many of those willingly to research the issue, test devices, and share that research. I don’t regret it, but I’ve also consistently underestimated the recovery time. Currently, I’m still working toward recovering enough from collecting/sharing flicker data in 2023 , although my guess when I finished that project was that I should be able to get to the point of having multiple symptom-free days withing a few months. It’s now over a year and a half and counting, although I’m slowly improving.
Using a screen enough to contribute to this forum is likely too burdensome to the health of some affected people who can’t use screens at all. And others may visit briefly but not be able to manage more. I’ve interacted with others in these groups through other connections.
Without research, what’s going on in my brain or anyone else’s as a result of flicker exposure is anyone’s guess. Similarly, research would be needed to determine whether any people are completely unaffected biologically by flicker. The bit of tangential public health research that exists - surveys of eye issues, headaches, and light sensitivity by optometrists surveying “digital eye strain” and finding about 70% of people affected with greater likelihood with more screen use - suggests that it’s possible that a very high percentage of people are affected to some degree.
