I have phoria when I occlude a red dot sight or irons.
I didn’t know what it was until @GJM linked me to this M4C thread that I encourage you to read posts #1 and #19. I had never heard of it in my medical education which isn’t surprising because eyes are kind of their own thing.

What this means practically is that if I occlude the dot, I will miss badly to one side or the other depending on which eye I am shooting with. It happens with pistols or rifles but much worse with rifles presumably because the dot is closer to they eye. And it is bad with a rifle: five -feet- to the side at 25 yards and a full foot off at 5.
My non colluded eye has a target focus and the taped dot is easily placed in the center of that target with no double vision or wandering. It’s just way the hell off. Doesn’t matter if I use my dominant or non dominant eye it just misses to one side or the other.
I believe this has something to do with the eyes converging and not wanting to diverge when I target focus due to a lifetime living at convergence for reading, too much screen time, surgery, and front sight focus.
When I missed so badly and honestly felt helpless to do anything about it, it reminded me of being completely inept starting Jiu Jitsu. I literally thought after trying taping the optic to work on my target focus that:
1. I am crazy or
2. Everyone is lying about hitting small targets with the optic occluded
I was experiencing a completely different reality from what everyone described taping the optic.
The good news is it completely corrects itself if I remove the tape from
the optic.
Anyway I am posting to see if anyone else experiences this or has been able to train it out? I would love to hear Gabe White’s input on the matter as he has explored vision so diligently. Or maybe any of you eye docs?
I actually think I could train the eyes to diverge better with diligent work but am unlikely to put in the work necessary.
