With my eyeglass prescription, it is all about the retractable eyecups, a large eyepiece and long eye relief. 19 to 20mm of eye relief works well. I am trying a new binocular with 17mm eye relief but it has a large eyepiece. The Swarovski 7x42 SLC works well but it is out of print.
I find that ~16MM is the least amount of eye relief and 17+ is better. Cameraland often lists the eye relief if you need to research a particular set. Meopta Meostar/Cabelas Euro in 32MM and 42MM objectives work very well for me w/glasses. Others that I own or have used that work well for me are Leica Geovids as well as Geovid HD-B in 8x, 10x, and 15x, Swaro SLC HD 15x56, Zeiss Victory RF in 8x and 10x.
