Section 1.8 APPLICANT NAVAL FLIGHT OFFICER STANDARDS
Must meet Class I standards, except as follows:
Visual Acuity, Distant and Near:
No limit uncorrected. Must correct to 20/20 each eye. If the AFVT or Goodlite letters are used, a score of 7/10 on the 20/20 line constitutes meeting visual acuity requirements.
Refractive Limits: Manifest refraction must not exceed +/-8.00 diopters in any meridian (sum of sphere and cylinder) with astigmatism no greater than -3.00 diopters. Refraction must be recorded in minus cylinder format. Must have no more than 3.50 diopters of anisometropia.
I don't know about the scar. Depending on what that is all about, it may be disqualifying or require a waiver, but I assume that a recruiter could help you get it checked out and help you get an answer.
