I'd go one step further and say dedicated computer glasses. They're designed for about twice the distance as book readers, and they have more expensive coatings (anti-glare and blue light filter) that are unnecessary for book readers. Since I invested mine (they aren't cheap), I can actually get through an article without printing it out to read it.
