You need 20/20 vision to become a pilot... especially a fighter pilot.
If you are interested in vision improvement, you can check out this site:

The site offers a program of eye exercises to improve your vision. Actually, the creator of the program, Orlin Sorensen, had a very similar situation like you... he wanted to be a pilot, but didn't have 20/20 vision. You can read his story on the site.
My vision is 20/400, which is really poor. I recently started doing the exercises to try to improve my vision. I created a blog where I record my progress with the exercises.
I recently saw some improvement. Other people (who have also experienced improvements) have posted comments about their experiences as well. You can check it out at: http://improvingmyeyesight.com/blog
Hope this helps....
