1faI can personally atetst to the fact that, at least ten years ago, astigmatism was not a disqualifier because I was eligible with astigmatism in my left eye. What you should do is first talk to the recruiter about what you need to do to get it waived. If the recruiter isn't helping or tells you there is nothing you can do, request to speak with their supervisor. It really typically is not a complete disqualier to the best of my knowledge, so keep at it.
