Lantern Test

[Unregistered]

Hi all,

Needing some medical advice (and yes I do feel it should be in this forum). I have a place with a company as a deck cadet starting in September and also an MCA ENG1 which says "fit for watch-keeping duties". I passed the ishihara plates at the ENG1, however I have failed the lantern test today for something completley un-related to my place in September. I have been classed as CP2 as I failed ONE of the lights consistently. Will this affect my career? I wasn't aware of needing a lantern test for the merchant navy, but what if I was made to do it at some point in the future?

If you passed the Ishihara test and have an unrestricted ENG1 then that is the test you will do each time you do the medical - unless you fail it. Therefore I would not worry about it.

You only need to do the Lantern Test if you fail the Ishihara test normally, so I cannot see you having to do it. Colour vision does not "usually" change over the years.

You need to say if you are Deck, Engine or ETO.

Anyone else seen this before?

So far as MCA medicals and vision tests are concerned, you only do the lantern test if you fail the Ishihara book.

Is failing the lantern test the same as not being able to tell the colour of a light at night?

My place is for deck. It is an odd situation I know hence it's in the anon forum. I'm assuming deckies only need to be CP2 as this is all the ishihara can determine. I was being tested for CP1 which it turns out I don't have, but the lantern test confirmed that I am CP2 which according to my ENG1 is okay for watch keeping

I'm not entirely sure, but I got a couple wrong in my lantern test purely because I was knackered. The room was completely dark and quite warm and my eyes kept closing and I got a few wrong. When he repeated them, I was fine. I also missed a few because I wasn't concentrating and so he repeated them.

I was lucky I think, because I'm a girl and so statistically unlikely to have colour-blindness, so the optician ran through some again and saw that I hadn't been concentrating/falling asleep. Had I been male, I have the feeling he wouldn't have given me the benefit of the doubt and I'd have failed. I have no issues with telling the colours of lights at night, but I very nearly failed the lantern test because I was sleepy.
