With all the talk of Long Arm Microscopes to add in watch repairing, I too have been looking into optical solutions to use.
I find after many hours using a standard loupe my dominant eye gets a little strained ... not to mention having lack of depth perception whilst working.
I was at my Dentist the other day, and she was using a pair of Carl Zeiss Stereo Optics to aid her, and I asked if I could have a look through them .... WOW OH WOW!!
Simply stunning vision!! So clear, and with a hug
