I have done most of my reading on eink devices since they first came out in the US. A year or two back I instead started doing most of my reading on my tab s2 8.0 (amoled) using fbreader. I swipe to adjust the brightness to what looks right at the time (usually a fairly low setting) and have been running the twilight app to reduce blue light (not sure if it matters or if it actually does). I have not noticed any additional eyestrain. I do notice the lower ppi on some eink devices like dpt-s1 and can no longer read on the lower ppi devices.

I did dislike reading on my older tablet which was not an amoled screen, but did not use it enough to test eyestrain.
