"You close your non firing eye with irons"
We are going to have to really disagree on this. First off by closing an eye you put a lot of extra strain on the one that is open. You immediately loose depth perception. The pupil constricts slightly due to more perceived light. Your facial muscles are now creating tension around the eye which causes it to change shape which can effect vision quickly and can even shift impact of your shots. For folks that close one eye, they will find that the sharpness of their sights quickly fades in about 3-4 seconds. On top of that you are closing off 1/2 of your vision which can be a real draw back in a dynamic environment or engaging a moving target.
Now it takes some practice to keep both eyes open and mentally use your dominant eye as the main vision source, but it isn't that hard to do, and if you must, you can squint your off eye a bit to aide making your dominant eye the main vision source, but don't close your off eye unless it's shoot like a pirate day!
Remember sight radius is your best friend when shooting iron sights, and I would venture that a good set of aperture sights... What most folks call peep sights, can rival the results of a scope sighted rifle as long as the target is visible to the "naked eye". Do scopes have their place? Oh hell yes! But irons can do some very fine shooting as well, it just takes a bit more training.
