Vision is evaluated with and without correction (corrective lenses or glasses are permitted).
Near vision: Candidates must have near visual acuity of 20/40 or better in both eyes either corrected or uncorrected.
Far vision: Testing each eye separately, candidates must have at least 20/30 or better in the best eye and 20/100 or better in the worse eye with or without corrective lenses; and with uncorrected visual acuity of 20/100 or better testing both eyes together.
The visual fields must not be less than 140 degrees and color vision is also required. Candidates who fail the standard color vision tests will be given the Farnsworth-Munsell D-15 Test. Stereopsis will also be tested.
Candidates will also have to pass a subsequent vision examination prior to academy appointment.
