It's been my dream to become a firefighter, but I am really worried about color vision requirements. Do any departments not have a color vision restriction? I can easily tell the difference on a particular color test where I was required to line up shades of colors from darkest to lightest, but that damn Ishihara dot test gets me. I just can't see the numbers. My color vision has never hindered me in the real world. I can wire anything without a problem.
