You would need laser vision surgery to fly in the navy/usmc. You could probably get a usaf pilot slot as-as if your vision doesn't get too much worse.

You do not need to be fighter pilot, military pilots who fly ant fixed-wing aircraft have great airline opportunities.

But military aviation (or any other officer job) is not just a job...you need to have an interest in the military and commit yourself to giving 100% for a few years. And at age 16, you probably don't have any idea of what 100% really means. I would probably get involved in athletics of some sort and try to get in shape if you really are considering the military...you still have time.
