I copied this from a second source web site so take that for what it's worth, but the key is the Army Regualation dated 27 June 2006, AR 40-501 ... specifically para 4.11-4.12. The only ... ONLY ... source I would trust is the local Flight Surgeons office.
You can find AR40-501 with a simple google search.
Vision Requirements Change for Aviator Wannabes
The Office of the Surgeon General recently approved a change in vision requirements for U.S. Army warrant officer aviator candidates to allow for corrected vision. Applicants for MOS 153A,
Aviator, now must meet the standards for the Class 1A flight physical (previous standard was Class 1). You are not qualified with uncorrected distant visual acuity worst than 20/50 in each eye and/or not correctable with spectacle lenses to 20/20 in each eye. You can view the full vision standards in para 4.12, AR 40-501. A change will be published to AR 40-501 to reflect the new standards, however, the regulation is currently under revision and is not expected to be published for 6 months to one year. Your local hospital or medical clinic may be unaware of the change so you should print a copy of the approval.
