Reading eInk in not enough light can also cause eye strain, of course.

What do you mean by "eye strain" then?
If you define "eye strain" (asthenopia?) by its symptoms (eye fatigue, headaches, soreness, itchyness), then isn't it a necessarily
subjective definition anyway? If a person doesn't experience any of the symptoms, then they don't have eye strain, do they? Wouldn't it be like saying, "You've got a headache, you just can't feel it"?
