Color deficiency USA and Canada
Hello,
I've got a new (not renewal) AME visit in USA few years ago for a medical class 1.
I've got the well-known "restriction for day only" due to my fail at Ishihara test plates. In fact I have not been tested on the famous classic book but on a "digital machine" (don't know the name) which also display dots and numbers. Note that I also failed on a lantern test once (don't know how many mistakes tho).
Recently my optometrist told me after some tests during a regular visit that I don't seem to be really color deficient, or just slightly.
I asked for a visit here in Canada for a Category 1. I passed the Ishihara book with maybe 1-2 light hesitations but no big deal and got a Category 1 with no restriction on it.
I also passed a D-15 test and succeeded at it with no mistake.
Question:
Is it possible for me to send my Canadian Ishihara test record to US FAA and ask them to remove my medical restriction?
If not, is it possible to do a new US medical Class 1 visit in order to be retested at Ishihara book? Is it something accepted?
Thanks
