I have this. Made me nuts for years. I tried everything.
Wasn't much of a problem with rifles and pistols, just closed one eye (left, because I shoot right handed) BUT SHOTGUNS????
After about three years of club shooting and ocasional sporting clays, a "noted expert" was traveling to a nearby clays course for two days and would be available for lessons at a houly rate that would pay the rent of my first apartment. What the heck, I was a DINK, and was at a plateu.
Anyhow, this guy stood about 5 feet away from me and instructed me to mount the gun, pulling up on his head, pointing my muzzle at his nose. Close one eye, close the other eye, both eyes open, get that piece of tape off your glasses, take one contact lens out...
After 10 minutes of this he said "You have central vision, I've seen it before. keep both eyes open until the gun hits your shoulder and slam the left eye shut as you pull the trigger (I shoot Churchill style), and NEVER GIVE IT ANOTHER THOUGHT" (emphasis his).
We went on to shoot for a while, he gave me some pointers and I hit some birds that amazed me.
My shooting became much more consistant and I was able to enjoy it more, knowing that 99% of the population has a dominant eye, and I had a "noted expert" tell me that I was among the 1% (or less) and I'd never have to wonder what to do again.
Money well spent.
Good luck, and don't become overly worried. Just keep shooting and try things (read, videos, etc) until you get a handle on something that works.
