Even with age, you can use irons, you simply have to have the glasses corrected...
And most don't understand that with irons you can only focus on one focal plane at a time.
Hence the most important thing is front sight. It helps to have the target clear and the rear clear to, but its not needed.
I had to shoot without correction with pistols becasue my eye could and would focus on the target paper at 25 yards, and gave horrible groups, NEEDED the target to stay blurry.
When in doubt put a peep on the rear, and even an aperture in the front.
As to success... lets just say paper targets you get used to, but with game, I've shot stuff so far away that most would call you a liar, luckily my longest shot with irons on small deer was witnessed by at least 3 others in the truck at the time..
YOu have to have the desire though, especially with irons, to learn how to use them, whats important and how to trust the sights and your eyes. Your eyes are capable of MUCH more than most give them credit for.
And before someone claims I have good vision, I had to have correction in my teens, and its never gotten better, only worse, and I didn't start shooting a LOT of irons until I was in my 30s, and carried on until appx 42 with irons in competition.
Having shot same with folks in their 70s plus, its still possible even as eyes age.
That's all fine and good, if your eyes can be corrected to a point.
But...
1. What do you do when glasses wont correct your vision, in your shooting eye?
2 What do you do when you have 9+ diopters astigmatism, in you shooting eye?
3. What do you do when the optic nerve has partially disconnected from the eyeball and there are gray areas (that see nothing), in you shooting eye?
4 What do you do when you cant focus on two items at the same time, unless they are the same distance from your shooting eye?
I could go on-and-on, but it would be useless. I grew up shooting iron sights and didnt shoot a scope until nearly 30 years old. Was I an expert with iron sights, no, but I did ok. Am I an expert with a scoped rifle, no, but I do ok.
I'm sick and tired of all the 'I can shoot better than you because I learned to shoot with iron sights and still do types.'
I'm glad you still have the eyesight to shoot the iron sights, and wish to God I did, but I dont and I can live with it.
Why cant you?
