Most places that sell generic reading glasses have a chart to give you an idea of the strength you need for reading. I think I saw 14" given on one of these charts.

My own suggestion is to use the distance that's comfortable for you to hold your reading material. --~--~---------~--~----~------------~-------~--~----~ Check us out at the oft-updated http://glassyeyes.blogspot.com!
