Many e-book reader programs (at least on Android) like Cool Reader or FFBReader offer the "Night" reading mode - basically, reverting from usual dark-text-on-light-background to light-text-on-dark-background.
Are there any studies showing whether there are benefits or downsides to one's eye health when reading books in "night mode" vs "normal mode" at night (low light) or during day (plenty of light)?
Ideally it would cover different display types, but personally I'm especially interested in ~5" LCD and AMOLED displays as on recent flagship Android smartphones.

From personal experience, switching to Night Mode helps reduce eye strain though it depends on whether you have a specific eye condition that requires you to read (e)books in Bright Light.
It's important to note that you should minimize your exposure to the colour blue if you intend to fall asleep (see: this page). It'd be best to adjust the blue tint of your screen but I do recommend colour inversion! It works wonders for eye strain!

This BBC article discusses the effect of of using e-book readers on your melatonin and sleep. It is based on this study.
The conclusion is that the blue light emitted by tablets and phones etc. can interfere with your sleep (but traditional e-book readers with passive screens do not).
So, those apps could help if they reduce the brightness or adjust the colour temperature (less blue) of the screen.

I found this article which explains how our body reacts to these LED devices (including ereaders). Near the end of the article, it says that programs that reduce the amount of blue light do actually aid you in getting a better nights sleep.
So, to summarize the article; blue light is what causes you to have a bad nights sleep after using a LED device (including ereaders). So, in order to reduce the blue light, you need to get rid of the bright colours. Programs for your computer, and night mode for your tablet do this effectively. Of course, this isn't a 100% solution, but it does help.
