Add me to the list of guys saved by the Farnsworth lantern. Sat in the doctors office and cried in the 7th grade when I found out I couldn't read the Ishihara cards. Tried to put the dream of flying jets out of my head until my Junior year of college.
Ran into an S-3 bubba in San Diego that passed this exact bit of gouge on to me.
Senior year of college I did my flight physical at Fairchild AFB (while applying to Navy OCS). They told my Navy recruiter that I had failed the color test. (Failed the Ishihara plates but passed the Farnsworth lantern). I was able to get the 0-6 running NAMI at the time to call my recruiter and explain Navy regs.
Here is the current Navy Ophthalmology waiver guide, reference color vision abnormalities, 12.2. The Farnsworth lantern gouge is still accurate.
