on lasik so I could use those guns without glasses...
Make sure you use a first rate eye doctor! Lasik usually is done to correct astigmatism and give the best possible vision at distance. If you are old and have poor accommodation (need reading glasses or "cheaters" for close work) this will not help you focus on the front sight!
They can do so-called "monovision" where one eye is over corrected to see near and the other corrected as normal for distance vision, but not everyone's brain can adapt to that situation. A good eye doctor will do trials with an extended wear contact lens in one eye to see how you deal with the adaptation before doing the surgery.
The "book" is non-dominant eye near, but I tried both and much preferred dominant eye near (especially when shooting) so that is what I had done. Its added about five years to my ability to use irons, but age marches on and my near point is now a bit in front of the front sight on most guns, but an aperture (or peep) rear sight helps a lot. But pretty much now I have to factor in red dot optics or scopes if I'm going to enjoy shooting.
OTOH, if you are young and one pair of glasses is fine for both driving and near work then Lasik will be great until about age 45 or so when the presbyopia stars kicking in
Another thing, not everyone is a candidate for Lasik, the key is the thickness of the cornea compared to the maximum pupil diameter. My wife's long time eye doctor was pushing to do Lasik on her as she was hitting the limits of what could be corrected with contacts (legally blind without them). I had her see my eye doctor and he immediately rejected her for Lasik. After a nearly 4 month workup with her not wearing contacts, but instead a series of "cheap" glasses so she could function and to let her eyes stabilize after most of a life with contacts he agreed to do PRK. This is much more invasive and has at least a month where you can't see worth crap. My wife was crying nearly every night worrying she made a huge mistake, but when she finally healed and could see 20/25 without contacts it was almost a miracle -- she still needed reading glasses (as she did with her contacts) but she is totally thrilled with the results.
Too many Lasik mills are out there not doing the proper workup and most of the horror stories out there about Lasik are from people who would not have been candidates for it with a proper workup.
