Eye dominance can even switch from shot to shot.
Coached a high school age girl with that, talk about a puzzle to diagnose! You see a difficulty in form, everyone has them. Have her adjust and she would start powdering them. And just when you're congratulating yourself for being a clever boy she starts missing cleanly again. Can make you a little nuts. Fortunately the frosted tape cure works very well in these cases with marginal dominance.
For those that don't know we're not talking about a big swatch of tape. All you need is a little dot of tape placed on the lens of shooting glasses between the eye and the target. Just enough so the target fuzzes up a little to encourage the dominate eye to take over. Some will use a little dot of Vaseline or clear hardening glue for a permanent fix.
