readily available during the exercise of the privileges of
the applicant’s licence.
Note 1.— 6.3.3.2 b) is the subject of Standards in Annex 6,
Part I.
Note 2.— An applicant accepted as meeting these provisions
is deemed to continue to do so unless there is reason to suspect
otherwise, in which case an ophthalmic report is required at
the discretion of the Licensing Authority. Both uncorrected and
corrected visual acuity are normally measured and recorded at
each re-examination. Conditions which indicate a need to
obtain an ophthalmic report include: a substantial decrease in
the uncorrected visual acuity, any decrease in best corrected
visual acuity, and the occurrence of eye disease, eye injury or
eye surgery.
6.3.3.2.1 Applicants may use contact lenses to meet this
requirement provided that:
a) the lenses are monofocal and non-tinted;
b) the lenses are well tolerated; and
c) a pair of suitable correcting spectacles is kept readily
available during the exercise of the licence privileges.
Note.— Applicants who use contact lenses may not need to
have their uncorrected visual acuity measured at each reexamination
provided the history of their contact lens
prescription is known.
6.3.3.2.2 Applicants with a large refractive error shall use
contact lenses or high-index spectacle lenses.
Note.— If spectacles are used, high-index lenses are needed
to minimize peripheral field distortion.
6.3.3.2.3 Applicants whose uncorrected distant visual
acuity in either eye is worse than 6/60 shall be required to
provide a full ophthalmic report prior to initial Medical Assessment
and every five years thereafter.
Note 1.— The purpose of the required ophthalmic examination
is (1) to ascertain normal visual performance, and (2)
to identify any significant pathology.
Note 2.— Guidance on the assessment of monocular
applicants under the provisions of 1.2.4.8 is contained in the
Manual of Civil Aviation Medicine (Doc 8984).
6.3.3.3 Applicants who have undergone surgery affecting
the refractive status of the eye shall be assessed as unfit unless
they are free from those sequelae which are likely to interfere
with the safe exercise of their licence and rating privileges.
6.3.3.4 The applicant shall have the ability to read, while
wearing the correcting lenses, if any, required by 6.3.3.2, the
N5 chart or its equivalent at a distance selected by that
applicant in the range of 30 to 50 cm and the ability to read
the N14 chart or its equivalent at a distance of 100 cm. If this
requirement is met only by the use of near correction, the
applicant may be assessed as fit provided that this near
correction is added to the spectacle correction already prescribed
in accordance with 6.3.3.2; if no such correction is
prescribed, a pair of spectacles for near use shall be kept
readily available during the exercise of the privileges of the
licence. When near correction is required, the applicant shall
demonstrate that one pair of spectacles is sufficient to meet
both distant and near visual requirements.
Note 1.— N5 and N14 refer to the size of typeface used. For
further details, see the Manual of Civil Aviation Medicine
(Doc 8984).
Note 2.— An applicant who needs near correction to meet
this requirement will require “look-over”, bifocal or perhaps
multifocal lenses in order to read the instruments and a chart
or manual held in the hand, and also to make use of distant
vision, through the windscreen, without removing the lenses.
Single-vision near correction (full lenses of one power only,
appropriate for reading) significantly reduces distant visual
acuity and is therefore not acceptable.
Note 3.— Whenever there is a requirement to obtain or
renew correcting lenses, an applicant is expected to advise the
refractionist of reading distances for the visual flight deck
tasks relevant to the types of aircraft in which the applicant is
likely to function.
Chapter 6 Annex 1 — Personnel Licensing
6-7 23/11/06
6.3.3.4.1 When near correction is required in accordance
with this paragraph, a second pair of near-correction spectacles
shall be kept available for immediate use.
6.3.3.5 The applicant shall be required to have normal
fields of vision.
6.3.3.6 The applicant shall be required to have normal
binocular function.
6.3.3.6.1 Reduced stereopsis, abnormal convergence not
interfering with near vision, and ocular misalignment where
the fusional reserves are sufficient to prevent asthenopia and
diplopia need not be disqualifying.
