I mentioned this a few days ago, but I'm leaning (ok, no pun intended again) towards nearsightedness if indeed EL didn't have her contacts on (I'm not saying she didn't have contacts on.) The distance the first time between her eyes and the buttons are roughly book distance. As a former nearsighted person needing glasses/contacts (with about -4.75 or something), I know how quick things can get blurry after a few inches or foot/feet. Anyway, LASIK is a great thing.
A far sighted person (not speaking from experience) would have difficulty focusing on near objects. If EL were farsighted, she would probably be more inclined to stand back from the buttons, rather than lean towards them.
Anyway, I think we're talking about the same thing.
Near sighted = can only see "near" objects clearly (depending on severity of nearsightedness)
Far sighted = can only see "far" objects clearly (depending on severity of farsightedness)
I'm not an optometrist, but something that resembles farsightedness is presbyopia, which occurs around one's 40's or 50's. That's losing the ability to focus, and since we see far when are eyes are relaxed, that leaves us seeing ok far (assuming we weren't nearsighted/myopic to begin with), we need reading glasses (for books, etc.) Some of us unfortunately end up needing bifocals to help us see far (from myopia) and near (from presbyopia.)
