With irons, focus is on the front sight, with target and rear sight out of focus.

Where is focal point with the red dot? Is it on the sight unit, or downrange at the target? Does the sight bring the target image to the sight's focal distance? Or are both eyes open and focused downrange?

Maybe I need to just get one of the sights, and play with it on a 10/22 or something to get smarter on how it works.
