The Zeiss Oberkochen 8x30B is a version of the 8x30 designed for eyeglass wearers. It has long eye relief and rubber eyecups that fold down. I believe this is an earlier version that has a much reduced field of view (50 degrees apparent). According to the literature, there was also a later version of the 8x30B with a wider field (60 degrees AFOV), produced after 1968 through 1978.
I found this 8x30 is definitely useable with glasses, although I had some problems with blackouts. The field is nearly sharp to the edge. I prefer the wider field of the normal Zeiss 8x30 model.
