What barrell length works for you as you get older? I have gone to shorter barrell like 3 to 4in instead of 6 to 8 3/8 for easier shooting .GETTING OLD SUCKS This is for general shooting like paper punching .
GETTING OLD SUCKS
If you can afford a special pair of glasses just for the range, you can get the front sight in focus with a single-prescription lens in your shooting eye and a plano (no prescription) in your off eye.
If you need cataract surgery, ask for one of those newfangled flexible replacement lenses that will restore the eye's ability to change focus. Presbyopia is caused by hardening of the lens, not loss of function of the focusing muscles. I have read, though, that it takes a few months for those muscles to work well, after having atrophied for years due to the stiff lens.
