As a bifocal eye glasses wearer, I have played with this issue a bit and found ways around my early troubles. I have single line bifocals, with the line relatively low, such that when shooting a scoped rifle I am naturally looking through the top portion.
I also have dedicated bifocal shooting glasses, two pairs with several sets of lenses. The reading portion of these glasses is small and very low, and is not noticeable during shooting, shotgun, rifle or handgun. Very easy to get used to these and easy to read a scorecard, etc.
With respect to using a binocular, I learned a very hard lesson many years ago that there is a wide disparity among binoculars in eye relief. I now have two with eye relief of 20mm which fill the bill. The glasses off business with a binocular is a bad idea, and I paid dearly for it many years ago in a missed opportunity.
