This is really interesting. Considering I've never had any symptoms reading a book, or getting my eyes irritated when playing badminton or boating in the open water on a sunny day - both of these activities involve either flicker or fast movement, it could be that a component to the eye strain really is the backlight, flickering or not.
This screen could be the solution. Of course I'm still doubtful if things like temporal dithering or flicker from just video could produce the same irritation as with a backlit display, but like I described, I'm able to tolerate "flicker" in natural light without any eye strain.
I joined the waiting list and will be ordering one the minute they become available.
I hope there would be some feedback already in this forum for those who have the most difficult version on these problems, e.g. getting eye strain from any display, like I currently have, since a few months.
