get a pair that the plastic eye cups twist in.. wearing glasses you have to fold down the ruber eye parts and they get brittle and brake because of that so having the ones that screw in helps alot.. personaly i use the nikon 7-15x35s
Be sure to consider magnification too. I bought a 10X and I wish I had gotten an 8X. The lower the magnification the easier it is to focus on the subject (image is less jumpy). I guess it depends on how steady you are. Try different magnificatons in the store.
I have a pair of leupold 10x rogues that the eyepieces turn in and a pair of steiner predator pros that have the rubber eyepieces. I use the steiners when I have the contacts in and the leupolds when I have the glasses on.
