Optometrists conducting eyesight examinations for seafarers who need to meet the requirements of Maritime Rule Part 34: Medical Standards should use this guidance.
What is Maritime Rule Part 34: Medical Standards?
Maritime rules contain detailed technical standards and procedures and form part of New Zealand’s maritime law. The rules are statutory instruments (or secondary legislation) made by the Minister of Transport under the Maritime Transport Act 1994.
Part 34 of the maritime rules relates to medical standards for seafarers and their fitness for duty. Rules are available on the Maritime New Zealand website: maritimenz.govt.nz/rules.
Who can conduct eye examinations for seafarers?
Seafarers wishing to gain a new deck certificate of competency or proficiency are required to have their eyesight and colour vision tested by a registered optometrist.
In the case of non-deck certificates of competency or proficiency (for example engineering and electrotechnical certificates), or for seafarers holding a current deck certificate and seeking renewal of that certificate, eye examinations are normally conducted by a medical practitioner as part of a medical examination for a certificate of medical fitness. However, if there is any doubt whether the seafarer has met the required standards, he or she may be referred to a registered optometrist for further testing.
Note: refer to appendix 2 for a list of certificates.
Note: optometrists are required to be registered
Any person conducting eye examinations requiring an optometrist must be a registered optometrist.
This is defined as: “A person registered under the Health Practitioners Competence Assurance Act 2003 with the Optometrists and Dispensing Opticians Board who has, or is deemed to have, a current Annual Practising Certificate and who is practising optometry in accordance with his or her scope of practice”.
What eyesight and colour vision standards are required?
The International Convention on Standards of Training, Certification and Watchkeeping for Seafarers (STCW) prescribes minimum standards for ships’ officers and ratings. STCW was adopted in 1978 by conference at the International Maritime Organization (IMO) (an agency of the United Nations) in London, entered into force in 1984 and was significantly amended in 1995 and 2010. The 1978 STCW convention was the first to establish basic requirements on training certification and watchkeeping on an international level.
Maritime New Zealand’s eyesight and colour vision standards for seafarers are set in accordance with the STCW Code, Section A-I/9. These standards apply to all Maritime New Zealand certificates of competency or proficiency, with conditions as shown in the following table.
See appendix 1 for Table A-I/9, “Minimum in-service eyesight standards for seafarers”.
The table below shows how eyesight standards are applied to maritime certificates (see appendix 2 for certificate definitions).

Maritime Rule Part 34: Medical Standards – Information for Optometrists
Eyesight considerations in relation to seafaring duties
Seafarers are required to pass eyesight and colour vision tests that relate to their duties on board ships. Seafarers who are required to keep bridge lookout duties need to meet more stringent requirements than those who don’t. However for shipboard duties such as engineering or electrotechnical functions, it is still important that specific standards are met.
For deck certificate holders, bridge lookout duties require good visual acuity and colour vision. Distant ships, markers and navigational hazards need to be seen and recognised, and charts and electronic displays need to be read precisely. Many navigational markers and lights are colour coded, including the navigation lights fitted to vessels, and it is vital that the bridge watchkeeper can differentiate between the colours used. Colour coding is also used for displays on navigational equipment, such as radars and electronic charting.
Non-deck personnel wishing to gain STCW certificates must also meet colour vision requirements. Seafarers with engineering or electrotechnical duties work with colour coded items, including electrical wiring, monitors displaying information, warning lights, pipe systems and other equipment. With regard to general eyesight, particularly near vision, gauges and instruments and other displays have to be read and monitored.
Eyesight and colour vision standards
Note: When completing an eyesight test report, please refer to the eyesight categories listed in appendix 3. See also appendix 1 notes on testing and STCW Table A-I/9.
Note: for GMDSS radio certificates refer to the engineering tests and standards given below.
General eyesight (distance vision values given in Snellen decimal notation with metre notation in brackets):
Distance vision (unaided) – 0.1 in one eye and 0.1 in the other eye
Distance vision (aided) – 0.5 in one eye and 0.5 in the other eye
Near/immediate vision – vision required for ship’s navigation (eg chart and nautical publication reference, use of bridge instrumentation and equipment, and identification of aids to navigation).
Visual fields – normal visual fields.
Night blindness – vision required to perform all necessary functions in darkness without compromise.
Diplopia (double vision) – no significant condition evident.
Colour vision – 38 plate Ishihara test with two errors allowed (see colour vision notes).
A fail result in the Ishihara test would normally mean that the required standard has not been met. However, if there is any cause for doubt about a pass result of the Ishihara test or the validity of the test result, the candidate should be further tested by one of the following:
a second pseudo-isochromatic (PIC) test (see colour vision notes)
a Holmes Wright Type B lantern test with two errors in two runs of nine pairs allowed
a spectral anomaloscopy conducted by a colour vision specialist (see colour vision notes).
In the case where an alternative test is required, Maritime New Zealand should be consulted before the test is conducted and may nominate the optometrist or colour vision specialist. Email: seafarers@maritimenz.govt.nz
For National deck certificates where colour vision requirements are not met, Maritime New Zealand may issue a restricted certificate that limits the exercise of privileges to daylight hours only.
Note: An examinee must not use colour vision aids when taking any colour vision test, including red-tinted, chromas lenses, and chromagen lenses. The use of colour-correcting lenses will invalidate test results.
Disease – there should be no evidence of serious or progressive eye disease.
Engineering, electrotechnical, and GMDSS radio certificates
Distance vision (aided) – 0.4 in one eye and 0.4 in the other eye
(6/15).
For engineering and electrotechnical (not GMDSS radio), combined (two eyes together) eyesight vision of at least 0.4 is acceptable.
Near/immediate vision – vision required to read instruments in close proximity, to operate equipment, and to identify systems/components as necessary.
Visual fields – sufficient visual fields.
Colour vision (not required for national engineering certificates) – 38 plate Ishihara test with two errors allowed (see colour vision notes).
In the case where the Ishihara test is failed, the candidate may be further tested by one of the following:
a Farnsworth D15 (dichotomous test, panel D15) test with one diametrical crossing being allowed
Notes on testing: the following is taken from Appendix A: Vision standards in “Guidelines on the medical examinations for seafarers” (International Labour Office / International Maritime Organization (ILO/IMO)), which is available on the ILO website: www.ilo.org.
All tests needed to determine the visual fitness of a seafarer are to be reliably performed by a competent person and use procedures recognised by the relevant national authority.
Quality assurance of vision-testing procedures at a person’s first seafarer examination is particularly important to avoid inappropriate career decisions. Please note:
distance vision should be tested using Snellen test type or equivalent
near vision should be tested with reading test type
Supplementary investigations such as lantern tests may be used when appropriate (see the International Commission on Illumination “International Recommendations for Colour Vision Requirements for Transport” (CIE-143-2001, including any subsequent versions)). The use of colour-correcting lenses will invalidate test results and should not be permitted visual fields may initially be assessed using confrontation tests (Donders, etc) and
any indication of limitation or the presence of a medical condition where visual field loss can occur should lead to more detailed investigation limitations to night vision may be secondary to specific eye diseases or may follow ophthalmological procedures. They may also be noted during other tests or found as a result of limitations to low-contrast vision testing. Specialist assessment should be undertaken if reduced night vision is suspected.
Maritime New Zealand note: limitations to night vision may be secondary to specific eye disease or refractive surgery that results in reduced contrast sensitivity. Where eye disease known to affect night vision is present or where the applicant has had refractive surgery, specific testing should be undertaken by an appropriate examiner.
Colour vision notes
Where an Ishihara test is not available, or if there is doubt about an Ishihara pass result for a deck certificate, an alternative pseudo-isochromatic (PIC) test may be used, the alternatives being the American Optical Company PIC Plates, the Bostrom Kugelberg Plates for Testing Colour Vision, the Dvorine PIC Plates, the Standard PIC Plates (SPP) or the American Optical Hardy Rand Rittler (AOHRR).
Fail criteria for a spectral anomaloscopy for a deck certificate is the mid-matching point (MMP) being more than + or – 2 standard deviations from the mean of the colour normal population, or the matching range is more than 3 standard deviations from the normal mean.
Fail criteria for a spectral anomaloscopy for non-deck certificates is a protan diagnosis as indicated by an excess of red in a red plus green mixture of colours to match yellow and a significantly lower than normal yellow luminance setting.
