As for my "instructions" for people? I'm sometimes shocked that this place is called MobileRead.

These statements are pretty clear: You believe that the majority of people who suffer from eye strain quicker when using backlit devices as opposed to non-backlit devices are just using the backlit devices incorrectly and, by inference, if we would just learn to use these devices correctly we would not suffer.
First statement: Yes and eye strain becomes worse as you age. That is what I was talking about in my first post. My vision is virtually the same as twenty years ago. What has changed is the fact that I now have bifocals (actually progressive lenses) and I can no longer use backlit devices comfortably for the same length of time as before. I practiced (and still do) "good habits" when using these devices and it does not matter. Age catches up with all of us.
Why do backlit devices increase eye strain? Don't know. I don't know if an LED LCD would be better as I have not tried one. Nor have I tried any of the other newer technologies. I am not in the "if it glows, it blows" camp because I have not tried all the glowing devices yet. I do have an e-ink device and I do know it is far easier on my eyes than my current LCD devices.
