Can't believe Apple didn't build this into their iOS! It is such a well know problem.
Perhaps Logos could add it. HINT! HINT! HINT!
Are you aware of f.lux?
EDIT: After I posted, I noticed that you're posting in the mobile forum so it won't work if your device isn't jailbroken. I therefore agree with you that it would be nice to have that option incorporated into the view options of the mobile apps!
Interesting. I was not aware of those studies on blue light.
It's nuts for each app to have to implement such a feature. This should be a system-wide thing.
Alternatively, you can just wear blue-blocking glasses/goggles, such as these, if using your digital devices in the evening:
Does that really work?
I recently purchased an LG Monitor that has a "reader" setting to remove blue light. It truly does help. I can now work within the Logos desktop application for hours without any eye strain. Its a big difference, especially in low light situations.

Yes! I have a pair and I wear them (when I remember to) at the computer after 8pm. I started doing this after going to a health retreat a couple of years ago where I was working on (among other things) my erratic sleep schedule, and that's where I learned about this technique for supporting a healthy circadian rhythm. Remember how I used to stay up until all hours of the night, posting on the Logos forums? Well, wearing the amber goggles and quitting Diet Coke cured me completely. I've slipped in my habits somewhat since then, but I know it worked and I know I can go back to that to get back on track. Amber goggles block blue light from the spectrum, and it's the blue light that interferes with the brain's generation of melatonin which helps regulate sleep cycles. So when you're staring at a white screen, there's lots of blue in that white (white is a combination of RGB). When you wear amber glasses, the images on the screen do look orangey, which can be bad if you're doing some Photoshop color correction work or something like that, and can make watching a movie a surreal experience. But for most work, including reading, and using Logos for other stuff, it's not that big a deal. Might make highlighting colors look different, but probably still distinguishable unless they are in the blue spectrum.
Perhaps Logos could add it.
This has already been discussed here and there is an existing UserVoice suggestion; please vote it up.
