I have actually administered the ishihara numerous times.... there are fourteen plates: the first plate is a green/orange plate that anybody who can see somewhere around 20/200 can read at the proper distance. This one is basically to ferret out people who may be trying to "fool the doctor." (Had a couple of those who were not so interested in being in the Navy anymore). From there it goes through 13 other plates that are variations of different color combinations with the last two being numbers on a gray background that most people easily get. Usually we flip through the book twice, once for each eye to make sure there aren't any discrepancies; however, I'm not sure the proper protocol for the DODMERB exam. They may just do it once with both eyes open.I've thought of that too or maybe each plate is actually 2 plates (both eyes) and the first plate is the example test.
They clearly wrote pass 2 and failed 12.
This again is the classic example of never even suspecting a color deficiency as none has been a problem in the past or detected. From what we (wife has perfect color vision, I'm iffy) observe is he sees color normally except for the Ishahara test obviously...lol. Oh well, time will tell and it is what it is.
