I was in your shoes, albeit a LONG time ago ('89)
I wanted NA, got selected for NFO with orders to AOCS. In my case, my vision was great. I had 20/15 in one eye and 20/10 in the other. Recruiter told me "due to numbers this month, you got NFO, needs of the Navy", BUT he said "don't worry, with your eyesight you can EASILY switch to NA once you get to Penscola and through NAMI" My mistake believing him, it is NEVER EASY to switch from NA to NFO, even before primary and especially after winging/sea tour.
Do some people do it? Of course, but there are very few spots, and it will take about 6 years before you can even apply for a transition (wait time, NIFE, wait time, primary, int, advanced, RAG, fleet tour)
In my case, I became an NFO, got the aircraft that I wanted, loved every minute of it and had no regrets. But I'd be lying if I said I didn't sit in the jet every day and wish I were in the left seat - especially seeing some of the knuckleheads that were there.
If you want to become a Naval Officer and fly, take the offer you have and make the best of it.
But if you're truly dead seat on being a pilot, 9 mos is not that long to wait. No guarantees you'll get a NA spot, but you might have regret if you don't give it your best shot.
Also concur with above - don't go cheap on LASIK, find the best doc you can, DO NOT shop docs based on price. it seems like a lot of $ now, but in the long run it won't matter, your eyes will
best of luck!
