Nath, you need 20/20 to get in the training pipeline, and if your vision gets worse than 20/30 in either eye before you finish training, you get canned. I was a navy hospital corpsman a few years ago doing flight physicals at Corpus Christi.
It is already waiverable to get PRK surgery to correct vision, or to wear glasses or contacts in flight. The catch is,
you have to have your wings already. To get into the program you still need 20/20. Now, the navy started a program last summer where they inducted a number of new trainees who had PRK surgery.
PRK will likely become a standard waiverable item for new student aviators in the near future. Notice, this is only for PRK right now. Lasik may be allowed in the future, but I haven't heard about that.
The exact standards are spelled out in Chapter 15-65, Manual of the Medical Department (NAVMED P-117), available
here.
If your vision is currently worse than 20/20, hold off on any surgery to correct vision. Go to school and get your degree. No, it doesn't need to be the Naval Academy... you can go anywhere you want. NROTC probably will help, but it isn't required either. By the time you're getting ready to graduate, the physical requirements will probably allow either PRK or Lasik, and you should be able to get in.
