I wrestled with this for years. Glasses are a huge PIA in the field. They fog up in wet weather like Alaska’s, and frost up in cold weather like Montana’s. One time I got 10 yards from a bedded caribou in the rain and had to take my glasses off and wipe them so I could shoot. Every time I rubbed them it made a little squeak, and the bull would turn around and stare. (I eventually killed him anyway.) My solution? Daily wear contacts! Don
