I don't know how good these things are, but they look interesting - stick-on magnifying lenses to allow you to read using your distance (or sun!) glasses, essentially turning them in to bifocals. It's probably not a long term solution for at home use, but might be useful for reading a map while you're riding.

If anyone tries them, please let us know how they work!

(Oh, and the only reason I haven't tried them myself is that my Lasik vision correction did not correct me to 20/20 - so in spite of the age of my eyes I can still read...)
