I recently had my first class physical done and didn't realize I had a color deficiency. On my medical it says "not valid for night flying or by color signal." Now I understand I can take the Farnsworth Lantern or Optec 900 test. So far, I've only been able to find a few places that actually have it. I live in North Carolina and was wondering if there is any doctor around here that can administer the test. Also, is there some type of "score" sheet the doctor needs to fill out?
