56, and I'm now wearing trifocals! And love'em...I made the eye doctor put them in three wide bands clear across the lens, instead of in those little scoop-shaped areas. I'm lucky still to have good peripheral vision and I want to see with it all in focus :) For most of my computer work, though, I had her make me a pair of glasses with just the medium prescription, to focus clearly on the screen....And I can't recommend enough an iMac with it's lovely flat screen that I can move up or down or back and forth with a fingertip :)
