The below disqualifying conditions are in addition to the disqualifying conditions listed in the Military Medical Accessions Medical Guide. Unlike medical waivers to join the military, medical waivers for aviation duty are much harder to come by.
The causes for medical unfitness for flying duty Classes 1/1A/2/2F/2S/3 are:
a. Classes 1/1A.
(1) Distant visual acuity. Uncorrected distant visual acuity greater than 20/50 in each eye. If the distant visual acuity is 20/50 or better in either eye, each eye must be correctable to 20/20 with no more than 1 error per line on the Armed Forces Vision Tester (AFVT) or projected Snellen chart at 20 feet.
(2) Near visual acuity. Uncorrected near visual acuity greater than 20/20 in each eye; with no more than 1 error per line on the AFVT or Snellen near visual acuity card.
(3) Cycloplegic refractive error using the method in ATB 5, Cyclopedic Refraction.
(a) Hyperopia greater than + 3.00 diopters of sphere in any meridian by transposition in either eye. (Spherical equivalent method does not apply.)
(b) Myopia greater than – 1.50 diopters of sphere in any meridian by transposition in either eye. (Spherical equivalent method does not apply.)
(c) Astigmatism greater than +/– 1.00 diopters of cylinder in either eye.
(d) Presbyopic correction greater than 0.00 diopters of add in either eye.
(4) Ocular motility using the methods in APL, Extraocular Motility Di urbances, and APL, Convergence Insufficiencies.
(a) Any degree of tropia detected in ocular motion on the Cover-Uncover Test (Tropia Test) in any four cardinal directions of gaze, or any degree of heterotropia.
(b) Esophoria greater than 8 prism diopters.
(c) Exophoria greater than 8 prism diopters.
(d) Hyperphoria greater than 1 prism diopter.
(e) Any detectable ocular motion on the Cross-Cover Test (Alternate Cover or Phoria Test) in any four cardinal directions of gaze until a complete evaluation by a qualified ophthalmologist or optometrist is reviewed by Commander, U.S. Army Aeromedical Center (USAAMC).
(f) Near point of convergence (NPC) greater than 100 mm.
(5) Color vision performed by test methods in APL, Color Vision Deficiencies.
(a) Five or more errors in reading the 14 test plates of the Pseudoisochromatic Plate (PIP) Set; or
(b) Any error in reading the nine test light pairs of the Farnsworth Lantern (FALANT).
(6) Binocular depth perception (stereo acuity) performed by test methods in ATB 7, Depth Perception Tests. (RANDOT Forms Test, RANDOT Animals Test, and Titmus Stereo Fly are not authorized.)
(a) Any error in line A or B of lines A through F when using depth perception presentation places in the AFVT or Optec 2300 AFVT; or
(b) Any error in levels 1 through 7 of the 10 levels of the Random Dot (RANDOT) Circles Test; or
(c) Any error in the nine levels of the Titmus Graded Circles Stereoacuity Test with nine levels of four circles; or
(d) Binocular stereo acuity worse than 40 seconds of arc.
(7) Field of vision. Any scotoma, other than physiologic.
(8) Night blindness. As noted by history and confirmed by abnormal night vision testing.
b. Classes 2/2F/2S/3. Same as Classes 1/1A, except as listed below:
(1) Distant and near visual acuity. Uncorrected acuity greater than 20/400 in either eye, which must be correctable to 20/20 in each eye.
(2) Manifest refractive error. Refractive error of such magnitude that the individual cannot be fitted with aviation spectacles.
(3) Failed NPC is not disqualifying.
