Donna, I was going to say before I saw your bifocal comment - yes, the easy way to increase the legibility for the presbyopic among us: Reading glasses.
Have a half dozen or so floating around, since my contact lenses let me see well now at a distance, but can't read well at all with them. *sigh Oh well, always said with the high rosy cheekbones, the greying of the beard/hair, weight gain, and now the reading glasses, will soon be able to start buying red suits with fur trim and wide black belts.
Also, just one more possibility, I seem to recall something in the accessories box in windows that acts as a magnifying glass. Been a while since I played with it, and I do not know if is still in the newer iterations of Windows.
JAAurand.
