My Answer: It is possible that your eyes are equally dominant and that can make the "two bead" effect more pronounced. Ultimately, however, it doesn't need to have any negative impact on your shooting. Assuming you don't have a dominant eye, the way to cope with the two-bead problem is to focus harder on the target. Put another way, if you're seeing two beads, you're looking at the wrong thing. Keep your eyes solidly locked on your target and the issue of seeing two beads drops by the wayside. With proper target focus the beads will become indistinct and blurry. As soon as your focus drifts to the bead, bad things start to happen—namely, you will slow or stop your shotgun swing and miss.
