Female Seafarers There should be no significant gynaecological disorder or disease likely to cause trouble during the voyage. Employment at sea shall not be permitted during the term of pregnancy. Visual Standards 1. No person should be accepted for sea service if any morbid condition of either eye, or of the lid of either eye, is present and liable to aggravation or recurrence. 2. New cases of monocular vision are unacceptable for any category of seafaring. However, monocular seafarers in the engine and catering departments with a satisfactory record of service prior to 1986 may be allowed to continue at sea in those departments. 3. Approved medical practitioners should use Ishihara plates to test for colour vision. 4. Distant vision and colour vision tests may be taken with or without visual aids (spectacles or contact lenses). However, an applicant who uses visual aid must reach the required visual standard for both aided and unaided vision. 5. Distant vision tests comprise a letter or shape test and are to be conducted on Snellen's principle at a virtual distance of 6 metres from the eye. 6. Unaided vision should be tested first and each eye must be tested separately. 7. In all cases where visual aids are required for the efficient performance of an applicant's duties, it shall be a condition of the validity of a medical fitness certificate that a spare pair is carried when seafaring. Where different visual aids are used for distant and near vision, a spare pair of each must be carried. Spare pairs of visual aids must be produced to the approved medical practitioner during the examination. 8. The following visual standards should be attained by an applicant intending to serve at sea in the departments specified- Department Standard (a) Deck Officers and Deck Ratings (including General Purpose Ratings) Age Below 22 years 22 years and above -Distant vision with or without visual aid Better eye 6/6 6/9* Other eye 6/9 6/12* -Distant vision without visual aid when visual aid necessary for above Better eye 6/36 6/60 Other eye 6/36 6/60 -Near, intermediate and colour vision, both eyes together, aided or unaided Vision required for ship's navigation (for example, chart and nautical publication reference, use of bridge instrumentation and equipment, and identification of navigational aids) -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* If the applicant marginally fails to meet this standard he should be referred to the Authority.
