Hey-
Advice from your friendly local flight surgeon.
AR 40-501, Chapter 2, governs enlistment and induction standards. You can find it online and it is a good resource if you can sort through all of the verbage.
Your vision, even on the MEPS physical, is not disqualifying. Per the standards, vision may be correctable to 20/40 in one eye and 20/70 in the other eye is Good to Go. Your measurements from the optometrist are uniformly within admission standards.
Your history of nystagmus is not disqualifying as long as it is no longer present.
Keep in mind the above assumes you are not applying for any of the Military academies, or OCS. Also, your vision must be correctable to 20/20 bilaterally in order to perform specialized duties such as Aviation service.
BTW, "disqualifying" does not mean you can't get in, it means you need a waiver.
Tell your recruiter to actually read the regulations.
