Anyone wear glasses whilst shooting and viewing their computer monitor?

I wear glasses, i slide them down my nose and look through the viewfinder with a "naked" eye, I just adjust the diopter to compensate.

I wear bifocals (distance and reading). I don't have any trouble with the viewfinder on either camera and sometimes use the LCD on the 590. I have a pair of reading glasses for computer use and recommend that. It lets me see the entire monitor instead of raising and lowering my head.

I wear my glasses while viewing through the VF. And sometimes it's a bother

Eyeglasses at the strength best suited for viewing PC monitors should be pretty good for viewing and focusing in the viewfinder. The typical viewfinder screen's apparent viewing distance is 30-36" (depending upon which brand of camera), so focusing is best when eyes handle that distance. The problem for older wearers of glasses is that distant vision correction is often too far for that apparent distance, and reading distance bifocals are too close for that apparent distance...the solution is the diopter correction, and viewing thru the distant vision part of focals.

I have been wearing glasses for just a few years, but I need them all the time now. So, I wear progressive bi-focals that are transitions and coated for non-glare all the time. On the computer, though, I have computer glasses that make everything look great about 2-3 feet from my face, but everything else is completely blurry. If I forget to take those off, I can trip over just about everything.
