Prying eyes do just that...they pry...(they spy for you). Read the spell, it makes eyes, the eyes fly around and are very fragile, they observe things for the caster and return to him.
Their use would be for scouting and spying, not speedreading.
Prying has several definitions including: insistantly or offensively curious, nosey, snoopy. None of these confirm your assertion in any way.
Well you do have a point there. The primary description of the spell effect is to create a number of eyes that "move out, scout around, and return as you direct them." Spying, basically. But then it also says this, which would seem to be the only specifics on HOW they accomplish that primary description- "When you create the eyes, you
specify instructions you want them to follow in a command of no more than twenty-five words. Any
knowledge you possess is known by the eyes as well." Emphasis mine.
So you have 25 words to instruct them and essentially they're YOU as far as understanding those instructions. The only reason to include that second sentence about what the eyes "know" is to define the scope of what you can command them to do.
The PHB gives these sample commands: “Surround me at a range of four hundred feet and return if you spot any dangerous creatures.”, and “Spread out and search the town for Arweth. Follow him for three minutes, staying out of sight, and then return.” So the eyes can interpret "dangerous" as far as what they can see about something and what YOU would define as dangerous: bunny (or dragon shapechanged into a bunny, because the eyes won't know the difference) = not dangerous, actual dragon = dangerous. They even 'know' "search the town for Arweth." Each eye that found Arweth would try to follow him for three minutes, and "stay out of sight" doing it, but they know who to look for AND they know what your idea of "search the town" encompasses.
But nothing in the spell description specifies they MUST be used for spying or "prying". That's just the name of the spell. Heck, if you define the spell by it's
name one could also argue its use is to force open locked doors and chests (another definition of prying.

). But the spell's
description disallows THAT kind of prying. It does allow for this: the eyes see 120' in all directions, know what you know and will follow a command of no more than 25 words.
While the easiest, most obvious way to use them is for spying, following someone or scouting an area (as the examples show); if you can figure out instructions (that YOU would understand) to make them read books and then move in certain way after finishing a page/book, then the eyes will do it.
