I’m having a problem shooting with both of my eyes open. It doesn’t matter where i have the diopter or parallax settings or what magnification the scope is set on. I’m seeing double vision. I have my eyes tested every 2 years (December 2016) and have 20/20 vision. The only way i can get a clear image is canting the rear scope cap to block my left eye. The scope I’m using is a athlon Argos btr 6x24x50 ffp. Could this just be me, or maybe because it’s a lower quality scope? Am i missing something? Any explanation or something to try would be greatly appreciated.
