I have older Leupold (green ring) Mesa's in 10X50's that work well when viewing with my glasses. I have always thought they were decent bino's, for the money but my hunting buddy who tried them on a recent scouting trip confirmed it. They have good glass for hunting purposes. For me, I have to dial each ocular eye piece in or out for the best performance since I wear glasses. Depending on your prescription and lens correction, each eye piece may have to be dialed in more or less for the best result. In my case, my right eyepiece is dialed all the way in and my left is dialed out slightly. Play with your bino's to find the setting that works best for you, whether you wear glasses or not.
