You could try QRead. It puts text in a standard edit control. Barring that, you could run it through calibre and convert to some other format. Both of these options require DRM free content, however. I'm not sure how much modification you can do on drm-ed content.

The problem may be a technical issue - you may be reading a PDF, which does not allow realigning text.
I read ebooks on a Kindle (although I prefer audiobooks). I can set the font type to one that is easy on the eyes (like Arial or similar), the boldness of the font, the size of the font (it can get really big if needed). There is also a backlight built in, so it works in dimly lit situations too. Way easier on the eyes than a phone, way bigger screen, but still quite small to carry it around.
