I too wear specs all the time (astigmatism) and I'd follow the advice of the others. If you do decide to go for correction dioptre lenses, check with the camera importer whether the dioptre label on the lens is the strength by itself, or is in conjunction with the inbuilt dioptre of the viewfinder. A few specialist shops might still have their sets of dioptre lens slides so that you can select the best for your sight. Today, Grays of Westminster, perhaps?
I was surprised to find that I've had to set the knob dioptre correction on my latest camera to near one end of its adjustment range. Normally I have it roughly in the middle.
(As I got older and my accommodation less, I found I needed a mild correction to place the virtual image within the distant field part of my bifocals - about -0.5D from memory, when I was using a Canon 50E.)
