Neijin, given what I and others have said (those that think this should work at least) your initial setup doesn't allow for the eyes to return to you or ensure that they'll read separate books and doesn't account for the limitations of what an unseen servants commandability. Cabral called it pretty well- once your eye reads the 10th page (therefore bobbing 10 times) it's book will get changed.
So here's maybe a better setup and instruction set. Set up twenty desks with all the books you want to read. Each desk has enough books to last 19 hours of reading and each book is open to the first page. Set an hourglass within sight of all the desks.
Tell the eyes, "Read books on desks, one eye per desk. Hover over your book. Bob once to turn page, move on when finished. Return after nineteen hours." The eyes know what you know, so they know the setup. The command may not be proper english, but it relays the necessary information. As long as you understand it is all that matters. They'll each read at their own desk, bob once to get the page of their current book turned and move on to the next book when finished with one. They can all see the hourglass so they'll know when nineteen hours is up. Set one servant to watch each desk and turn the page of whatever book the eye is hovering over whenever it bobs once. Another servant turns the hourglass when it empties.
Once you've set this up as your "research drill" you could make the command even more 'shorthand' then that- cast prying eyes in the library with the command "research mode, 19 hours, go." As long as you've established and understand what that means it's arguably a valid command. If your wizard has a military background (or just the mindset to do it) you could have all sorts of "recon commands" for when you cast prying eyes.
