All of the fixed power eyepieces have substantially more eye relief than the zooms. Unlike the zooms, I find them all comfortable to use with glasses. Of the 30x and 38x options on the 82ED, the eyepiece with the smallest eye relief is the 30x MC, the 38x MC has a bit more, and the 30x DS has the most. I can't really tell the difference between the latter two in use, but the shorter eye relief of the 30x MC is sometimes apparent when I'm trying to grab a quick look through the scope from odd angles. So the 30x DS, which also has a slightly flatter field, is my favorite. Another option is the older 30x WF. It is the same optical formula as the MC version yet is considerably narrower in diameter because it has a folding eyecup. Consequently, I find that it has effectively more eye relief than the MC version even though the spec is the same.
