Not to derail the thread, but I get a POI shift with an occluded pistol optic. I'm right handed and right-eye dominant, and bullet impact is significantly left when my optic is occluded. Any idea why this happens for some shooters?

Has an eye doctor ever told you that you might now have binocular vision? Like your right eye sees things and your left eye sees things, but your brain doesn’t merge the two images together? At closer ranges like 3-5y, is the distance between your POA and POI about the same as the distance between your eyes?
I also experience this intermittently, especially if tired. I had a retina tear nearly ten years ago in my right dominant eye, still have significant floaters, and in some lower light conditions, my left eye fights for dominance.
Back to the SRO, a squad mate who is a lead red dot trainer for a major department, had his SRO occluded on the first stage. I meant to ask him, but didn't get the chance, how the department would feel about an occluded SRO on duty. The false SRO dot is such a problem, because rather than being splatter that you know is a problem, it is a single deceptive dot.
I was playing around with a PVS-14 night vision tube on my left eye and aiming with a visible dot on my right eye. Same problem. It's a convergence issue, and can cause big deviations in POI. See this article by Gabe White: http://www.gabewhitetraining.com/vision/
I've never had an eye doctor tell me that I have binocular vision. But my eyes are kind of wonky, so I could well have it. My POI shift is 1.5" left at 7 yard, which is near to the distance between my eyes. Interestingly, the POI is also about 1" low with the optic occluded.
I have a torn vitreous in my left eye, and tons of floaters. And both eyes have had cataract surgery due to early-onset cataracts. BTW - thanks for your ongoing discussion and photos of false dots - it's valuable information.
I've read that article a few times over the years, while trying to figure out why Gabe is such great shooter. I'll re-read it again, within the context of occluded optic POI shift. And please feel free to break this out into a separate thread, if you think it makes sense.
I appreciate your input. I got into my circumstances and all that upstream.
I’d carry a SRO, if I did, it would be occluded, and I’d be ok with that.
I have an aimpoint P2 inbound that I was fortunate enough to get a great deal on. So I guess I won’t be killed on the street at sundown after all. Ha
