PART 4 PROCEDURES FOR THE CONDUCT OF EYE AND VISION TESTS

1.0Purpose
These procedures are established to ensure the standards established in Part 2 are met.
(a)for distance vision without corrective lenses, visual acuity of at least 6/60 in both eyes; and
(b)for distance vision with corrective lenses, visual acuity of at least 6/12 in both eyes; and
(c)for near vision, vision required for ships navigation; and
(d)normal visual fields.
2.0General requirements
A seafarer must—
(a)take and pass a letter test; and
(b)either—
(i)take and pass any colour vision test required in Part 2; or
(ii)satisfy the recognised optometrist or recognised medical practitioner that he or she has previously taken and passed any colour vision test required to meet the standards in Part 2 and that test pass is still valid under clause 5A.3 of Part 2.
3.0Conduct of eye and vision tests for issue of certificates of competency for seafarers by recognised optometrists
3.1Eye and vision tests for certificates of competency for seafarers who are masters, mates, or deck ratings must be conducted by a recognised optometrist.
3.2For the assessment of acuity, refractive status, or fields, the recognised optometrist must use methods consistent with current best practice.
3.3A seafarer must show photographic identification to the recognised optometrist before taking an eye and vision test.
3.4If a seafarer takes both a letter test and a colour vision test, the letter test must be performed first.
3.5The recognised optometrist must establish, at the time of the tests, if there is evidence of serious or progressive eye disease, which includes congenital night blindness, diplopia and retinitis pigmentosa.
3.6If the recognised optometrist finds evidence of serious or progressive eye disease, the optometrist must advise the seafarer and the Chief Executive Officer of those findings, including any review of the disease required by the optometrist to check on the progress of that eye disease.
4.0Purpose of the letter test
The purpose of the letter test is to test visual acuity.
5.0Conduct of a letter test
5.1The letter test must be conducted on Snellen’s principle by means of charts of letters.
5.2A seafarer may elect to take the letter test with or without corrective lenses.
5.3A seafarer who elects to take the letter test with corrective lenses must first take the test without corrective lenses to ensure the seafarer still meet a lower standard of visual acuity without corrective lenses.
6.0Administering the letter test
6.1The test chart used for the letter test must be—
(a)properly illuminated; and
(b)mounted at a convenient height.
6.2The testing room must be moderately lit.
6.3The seafarer must—
(a)face the chart from a distance of 6 metres, or by any other approved means that produces a 6 metre range; and
(b)read each line of the chart from left to right commencing at the top of the chart.
6.4A seafarer must not squint during the test (ie the palpebral aperture must not obstruct a clear entrance pupil).
7.0Failure to obtain standards
7.1A seafarer who fails to meet the standards for visual acuity, set out in Part 2 for binocular or monocular vision as applicable, may only be re-tested once.
7.2If a seafarer fails to meet the requirements set out in Part 2 for binocular or monocular vision as applicable, the following options must be explained to the seafarer:
(a)the seafarer may discontinue testing and return for one further test at a later date; or
(b) the seafarer may proceed to the colour vision test but—
(i)all mistakes (made in the letter and colour vision tests) will be recorded; and
(ii)the Chief Executive Officer will be advised of the results of both tests.
8.0Purpose of the colour vision tests
The purpose of the lantern colour vision test and Ishihara plate colour vision test is to test colour vision.
9.0Colour vision aids
9.1A seafarer must not use colour vision aids when taking any colour vision test.
9.2Colour vision aids include red-tinted, chromas lenses and chromagen lenses.
10.0Conduct of the Ishihara plate colour vision test
10.1Conduct of the Ishihara plate colour vision test
10.2The plates must—
(a)be viewed by the examinee from a 50 cm distance; and
(b)be perpendicular to the line of sight of the examinee; and
(c)not be held by the examinee.
10.3A seafarer must take the Ishihara plate colour vision test with the best possible visual acuity.
11.0Failure of the Ishihara plate colour vision test by examinees for certificates of competency for masters, mates, and deck ratings
11.1If a seasfarer for a Certificate of Competency who is a master, mate or deck rating, is tested by a recognised optometrist, and fails the Ishihara plate colour vision test, the recognised optometrist must advise the seafarer that he or she must take the lantern colour vision test.
11.2If the seafarer fails the Ishihara plate colour vision test and then fails the lantern colour vision test, the recognised optometrist must advise the seafarer that he or she may take the special colour vision test prescribed in clause 13.0.
12.0Conduct of the lantern colour vision test
12.1The seafarer must take the lantern colour vision test with the best possible visual acuity.
12.2A Holmes Wright Type B lantern and mirror must be provided for the lantern colour vision test.
12.3The lantern colour vision test is to be conducted in a darkened room so as to exclude all artificial light and daylight.
12.4The lantern must be placed—
(a)directly in front of the mirror so that the front part of the lantern is exactly 3 metres from the mirror; and
(b)in such position that the lights reflected in the mirror show clearly when viewed by the seafarer seated close to the lantern.
12.5The lantern colour vision test must begin with a series of lights shown through the large aperture followed by 3 complete circuits through the small apertures.
12.6Except as provided in subclause 12.7, the seafarer must name the colours of the lights as they appear.
12.7When asked to name the lights shown in horizontal pairs, the seafarer must be instructed that the light on the left must be named first.
12.8If a seafarer makes a mistake at the beginning of the lantern colour vision test, the seafarer must be kept in a completely, or partially, darkened room for at least 10 minutes for darkness adaptation, and may then re-start the test.
13.0Special colour vision test
13.1An examinee who fails the lantern colour vision test may apply to the Chief Executive Officer to sit a special colour vision test.
13.2The special colour vision test must be conducted according to clause 12.0 and to the standards required by Part 2.
13.3Special colour vision tests must be conducted according to clause 12.0 and to the standards required by Part 2.
14.0Results of eye and vision tests conducted by recognised optometrists for certificates of competency
14.1Subject to subclause 14.2, the recognised optometrist who has conducted an eye and vision test for a Certificate of Competency must—
(a)record the results of all eye and vision tests on an approved eye and vision test report form; and
(b)forward the form to the Chief Executive Officer; and
(c)provide a copy of the form to the seafarer.
14.2If there is any doubt as to whether the seafarer has passed a test, or any evidence that the seafarer may have serious or progressive eye disease, the recognised optometrist must—
(a)refer the complete results of the seafarer’s eye and vision tests to the Chief Executive Officer for the Chief Executive Officer’s decision on whether the seafarer has passed; and
(b)advise the seafarer that his or her results are being referred to the Chief Executive Officer.
14.3If a recognised optometrist refers the results of any eye and vision test to the Chief Executive Officer under subclause 14.2, the Chief Executive Officer must, after consultation with the recognised optometrist—
(a)decide whether the seafarer has passed the eye and vision test; and
(b)issue an eye and vision test report form to the seafarer advising the seafarer of that decision.
15.0Recording of the results of eye and vision tests conducted by recognised medical practitioners
The results of eye and vision tests conducted by recognised medical practitioners must be recorded on the Certificate of Medical Fitness for Seafarers.
16.0Notwithstanding the medical standards prescribed above in this Schedule, the ILO/IMO Guideline on the medical examinations of seafarers is applicable to this Schedule.
