You don’t have to be 20/20 without glasses, just correctable to that with some other top number (maybe 20/200, just a guess), so you likely don’t need surgery.
The real problem is you need an age waiver, because you are too old now for UPT. It’s possible to get one but not probable. They have plenty of applicants who don’t need one. I’d say your best bet is finding a unit that flies undesirable aircraft and is in an undesirable location. There will be less competition there. Not saying give up entirely on other units, but trying to give you a realistic outlook.
