JAR Class 1 (Professional Pilot) Initial Examination Visual Standards
These are the JAR Class 1 visual standards as applied by the UK CAA.
Distance Vision
Your visual acuity (measured by your ability to see, in this case, lines of letters on a chart at 6 metres)
must be at least 6/9 in each eye separately and 6/6 using both eyes together, with or without glasses or
contact lenses (correction). If you need correction the refractive error (the amount of correction) must
not exceed +5.00 dioptres of long sight or -6.00 dioptres of short sight. This is in the most ametropic
meridian (taking into account any astigmatism). Astigmatism must not exceed 2.00 dioptres. The
difference in correction between each eye (anisometropia) must not be more than 2.00 dioptres. Your
optometrist will be able to explain these terms.
Near Vision
On the standard near vision eye chart you must be able to read the N5 print between 30 and 50 cm and
the N14 print at 100 cm, with or without correction
