So I'm guessing if we want to read at night, it's better for our eyes to:
a. read in a lighted room,
b. prefer using a non-frontlit e-reader over a frontlit reader or LCD. If the ambient light where you are seated is not enough, then attaching an auxiliary booklight to the non-frontlit e-reader is slightly preferable to a frontlit e-reader with its more uniform light (the auxiliary booklight generally won't reflect evenly across the e-reader, so the distribution of light over your retina is more varied.
In your judgement are those the correct best practices for e-reading at night?

You are letting yourself get confused by amateur fabricated "science", or grasping at something that suits your agenda.
The comparisons regarding the fovea only apply to looking directly a strong concentrated source of light, such as looking directly at the candle itself very close up or into a larger strong light such as a lamp. What has been described would apply, for a device example, if looking into a phone or tablet's camera's/torch high intensity flash LED.
Nothing to do with low level light emitting or reflective displays because they have comparatively large plane surfaces relatively evenly and lowly lit and in the cases of E Ink and LCD also diffused.
But like drowning men there are some who will hear nothing that is contrary to their claims of danger and will continue to try to convince people by quackery and fabricated "science" in order to support their argument. Nothing will change their minds but hopefully threads lead by a claim such the OP has stated will encourage those of more rational thought to question scaremongering claims as to the safety of displays.
