Mrs Fester was 20/400 and got an NFO slot. That's legally blind. Navy doesn't care, as long as you're correctable to 20/20 and no other vision issues (color vision, depth perception, etc).
My opinions on the SWO community are nearly 10 years time-late now in terms of actually being one, as opposed to what I saw of the Shoes on the Boat. Nothing I saw then or since has given me any cause to change my opinion, but that's not the point. Some of our visiting current Shoes here tell me I'm wrong and I have no current info to contradict them, so I'll yield the floor on this particular issue. Suffice to say, I hope to G-d the community has changed for the better since ENS Fester was getting flame-sprayed on his trusty Left Coast battle frigate.
