Here it only explains USMA I am wondering the rules on the merchant marine and coast guard academy. also I hear the rules for USNA are correctable to 20/20 Current distant visual acuity of any degree that does not correct with spectacle lenses to at least one of the following (367) is disqualifying: (1) 20/40 in one eye and 20/70 in the other eye. (2) 20/30 in one eye and 20/100 in the other eye. (3) 20/20 in one eye and 20/400 in the other eye. b. However, for entrance into USMA or ROTC, distant visual acuity that does not correct to 20/20 in one eye and 20/40 in the other eye is disqualifying. For entrance into OCS, distant visual acuity that does not correct to 20/20 in one eye and 20/100 in the other eye is disqualifying. c. Current near visual acuity (367) of any degree that does not correct to 20/40 in the better eye is disqualifying. d. Current refractive error (hyperopia (367.0), myopia (367.1), astigmatism (367.2)), or history of refractive error prior to any refractive surgery manifest by any refractive error in spherical equivalent of worse than -8.00 or +8.00 diopters is disqualifying. However, for entrance into USMA or Army ROTC programs, the following conditions are disqualifying: (1) Astigmatism, all types over 3 diopters.
