I don't have that problem. I find find ragged-right with no hyphenation less pleasant to read and to look at. When I'm reading a novel on my Kindle, I have it set ragged-right because the Kindle doesn't justify well (just word spacing I think). Same on the web. But when I can get good justification and hyphenation, like on a properly typeset PDF or physical book, I prefer it.
