Seeing as we're on the subject of Submariners.
I just recently applied to be a Warfare Officer (Submariner) in Her Majestys Royal Navy.
I have a formal interview and a selection exam end of this month before I can even think of going to the Admiralty Interview Board...anyways I digress.
-0.25 is nothing in an eye. Yet thats how much I'm out by in my left. Yet I can be a Royal Marine or a RM Officer. I did a year in the Reserve Infantry and I can safely say you need ebtter eyesight as a slogger then an officer onbaord a submarine.
A very Big, Whisky, Tango, Foxtrot on that one.
