> my eyes hurt when reading an e-reader You are not supposed to get eye strain with e-paper. There's no light source. I mean, newer ones have 'backlight', but you can just turn it off. For me it's good because I can make the font bigger, so less eye strain. Also, at least for a kindle paperwhite (older 2018 model, I think), it's very slow to do anything on the internet, so I never used it save for checking the next volume of a book on the amazon store.
