After wearing contacts for more than 30 years, I now must wear glasses. I'm having a hard time making the adjustment with my binoculars. I am aware that I need to turn the eyecups down. My binoculars have eye relief of 16.5; not something I had to pay attention to when I bought them. I would love to know if other eyeglass wearers have any tips or tricks to offer. Please reply off list. Thanks much! Diane Cavaness Brookings
