Years ago I applied (and was accepted) to a special assignment in the US Marines that required perfect vision including color vision. I took a few weeks leave, went to Canada (so there'd be no US medical records) and got lasik and ChromaGen contact lenses. Passed all the vision tests. For me this was the only thing that stood between me and a very cool assignment. Edit: I eventually passed the Ishihara test (colored dots) where I previously failed it.
