[I've just asked this question on the Zeiss sub-forum (where I got some very helpful and encouraging responses - thanks folks), but I've just realised that there's also a more general binocular forum - Doh!]
Unfortunately I need to consider changing to bifocal (or varifocal) spectacles - so that I can read maps, use an iPod, consult field guides, tell the time, see my feet, etc as well as looking at distant objects, eg birds!
I use Zeiss Victory 8x32 T* FL binoculars for birding - which work really well with my current (conventional) specs.
I'd be very grateful if others could share their experiences of using bins (and 'scope) with bifocal or varifocal specs.

I have progressive bifocals (the ones that show no edge). I have not noticed any difference or had to modify my viewing habits through binoculars or scopes in any way compared to when I did not have bifocals.
