Glad to hear you are getting off of the pain relief. Although a blessing when it is needed, it is depressing and slowing and generally blah making to life in general.

Re fuzzy vision and reading. Personally I depend a lot on audio books, downloaded to my Ipod for reading. I have few opportunities to sit and read but I can fall asleep listening to a book, and as for the obligatory treadmill and elliptical cardio training and exercise when not riding, I couldn't survive without it.

The added benefit to listening when I fall asleep is that my brain treats it as white noise and stops listening after about 15 minutes which means that a a 20 hour book can last as long as 40 hours.

My local library has an extensive collection of audio books which can be downloaded off their central computer or borrowed and downloaded through ITunes.

You might also want to take a very close look at your fit after you get back on your bike and get used to riding again you may find it has changed. My posture changed a lot.

hang in there and keep healing.
