A few years ago, my eye doctor suggested I read large print books when I can to help with eye strain. It was only for a few months as we figured out what kind of glasses worked based for my extremely poor vision (4 years between visits isn't recommended anymore, lol). However, I found that I liked the format better, especially since the font is usually standard across all books. I'm grateful that my library and the overall state system buys large print versions of new releases. The patrons at the library I manage don't mind reading large print, either, which frees up money for other books since we don't need two different copies!
