last time i asked them about the eyesight requirements...
whoila.....
at least 6/60 without optical aid. if eyesight is worst than this, a full-opthalmology check is required to ensure that the eyesight is normal and doesn't have any defects or sickness.....
no mentioning about dioptress limit.
Visual Acuity Test Requirements
36. For the purposes of paragraphs 37 to 41 —
(a) each eye of the applicant will be tested separately; and
(b) the methods of testing visual acuity shall be as follows:
(i) visual acuity tests should be conducted in an environment with a level of illumination which corresponds to ordinary office illumination (30-60 cd/m2);
(ii) visual acuity should be measured by means of a series of Landolt rings, or similar optotypes, placed at a distance from the applicant, as appropriate to the method of testing adopted.
37. The function of the applicant’s eyes and their adnexae shall be normal. There shall not be any active pathological condition, acute or chronic, nor any sequelae of surgery or trauma of the eyes or their adnexae likely to reduce proper visual function to an extent that would interfere with the safe exercise of the applicant’s licence and rating privileges.
38. —(1) The applicant must have normal fields of vision.
( 2) The applicant must have normal binocular vision.
Note: Defective stereopsis, abnormal convergence not interfering with near vision, and oscular misalignment where the fusional reserves are sufficient to prevent asthenopia and diplopia may not be disqualifying.
39. —(1) Distant visual acuity with or without correction shall be 6/9 or better in each eye separately and binocular visual acuity shall be 6/6 or better. No limits apply to uncorrected visual acuity. Where this standard of visual acuity can be obtained only with correcting lenses, the applicant may be assessed as fit provided that —
(a) such correcting lenses are worn during the exercise of the privileges of the licence or rating applied for or held; and
(b) in addition, a pair of suitable correcting spectacles is kept readily available during the exercise of the privileges of the applicant\'s licence.
(2) An applicant accepted as meeting the requirements in this paragraph is deemed to continue to do so unless there is reason to suspect otherwise, in which case an ophthalmic report will be required at the discretion of the evaluating medical examiner who shall require that the applicant’s visual acuity be measured and recorded at each re-examination.
(3) 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.
(4) An applicant may use contact lenses to meet the requirement in this paragraph 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: An applicant who uses contact lenses may not need to have his uncorrected visual acuity measured at each re-examination provided the history of their contact lenses prescription is known.
(5) An applicant 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) An applicant whose uncorrected distance 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 5 years thereafter.
Note: The purpose of the required ophthalmic examination is to ascertain normal visual performance and to identify any significant pathology.
(7) An applicant who has undergone surgery affecting the refractive status of the eye shall be assessed as unfit unless he is free from those sequelae which are likely to interfere with the safe exercise of their licence and rating privileges.
40. —(1) The applicant shall have the ability to read, while wearing the correcting lenses, if any, required by paragraph 39 (1) of this Schedule, the N5 chart or its equivalent at a distance selected by that applicant in the range of 30 to 50 centimetres and the ability to read N14 chart or its equivalent at a distance of 100 centimetres.
(2) If the requirement in sub-paragraph (1) 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 paragraph 39 (1) of this Schedule;
(3) If no such correction is prescribed, a pair of spectacles for near use shall be kept 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.
(4) 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 he is likely to function.
Note: An applicant who needs near correction to meet the requirement in sub-paragraph (1) will require "lookover", 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 his lenses. Single-vision near correction (full lenses of one power only, appropriate for reading) significantly reduces distant visual acuity and is therefore not acceptable.
41. When near correction is required in accordance with this paragraph, a second pair of near correction spectacles shall be kept available for immediate use.
