World War I Spies Caught by Woman Who Read Invisible Ink

... and her acuity was prompted by her previous experience with boyfriends.

I can apparently see so called invisible ink. I wear glasses. They mark the lens before grinding to fit your frames with an ink that isn't supposed to be seen except under UV light. For some reason I can see it on my lens whenever they forget to clean them off before giving them to me. First time it happened I couldn't figure out what the hell I kept seeing after I got my new glasses. Went back to the optometrist and told them I keep seeing these numbers and lines. They first examined my eyes to see if I was having issues with my retina, when that came back ok. Then they took the lens to the lab tech and he saw that they forgot to remove the stuff they mark on the lens. They said they've never met anyone that could see that stuff without the UV light. Its happened once since then. I can't see worth a dam without glasses but I can sure see the ink they use to mark the lens with.
