That isn't quite right, since the regular prescription is for nearsightedness, and thus a minus prescription. A reading or computer prescription would be weaker in the minus direction, and with a weak minus prescription to begin with, they might go into the plus direction. The original inquiry is a good example of this. My guess is that the reading prescription would be somewhere in the +0.50 to +1.00 range. Try reading with +1.00 at a local store. (I've never seen a weaker prescription than +1.00 at local stores; If you happen to find any, try them, too). If that seems too strong, get an inexpensive pair online with about +0.50, and you should probably include your CYL prescription, too, though you might want to ask your eye doctor about that. Use the smaller of your two PD values. If the +1.00 seems too weak, local stores should have glasses that go up in the standard 0.25 increments from that. --~--~---------~--~----~------------~-------~--~----~ Check us out at the oft-updated http://www.glassyeyes.com!
