I've been trying to understand that "affliction and/or variance-from-normal" for years -- A LOT of them!. I've been unable to understand what people were seeing (and/or thinking they were seeing?) with all the dominant eye test "stuff". That just didn't work for me -- as in, "OK, which one of those holes do you want me to look thru? -- which thumb am I supposed to be looking at?".

With a shotgun, handgun, or open-sight rifle I always see two barrels. For years I thought this was normal and just what everyone else was seeing. I learned to deal with it. Over the years it has just become automatic as to which barrel or set of sights I needed to be looking at. I'm not sure but I think the "feature" I was blessed with must might improve my depth perception.

All the best,

Glen
