Certainly. I like a nice eyecup, and this one's pretty nice. A bit on the soft side, but that has its comforts.
My own glasses aren't the same shape, so it's an odd fit if I shoot through them, and the lenses are all banged-up, so it's hard to be sure, but I think for bigger ones, it's probably OK, at a guess.
They sell the KPS with a rubber flat ring as well as the cup, for a little more, and that Tenpa one Time Bandit mentions looks like a quality item, and has them, too. Comes in a couple of different magnifications, too, if I recall.
